Frelux Synergy 1 Review (Custom EDC Light)

The light I have here is the FreLux Synergy1 pass around light, that has been going to various forum members to play with and review if that is what they do. This is the first review I am aware of that features the updated driver, with the high CRI Nichia emitter. It’s brighter than the previous and has better mode spacing. I didn’t buy it and by the time you have seen this review it will be sent on to the next lucky pass around member. Thanks to Benjamin and /u/ozythemandias for letting more people try this new little light.

YouTube Version of this Review:

The Synergy 1 comes in a small Altoids sized tin. There is laser cut foam that fits the light perfectly. Inside is a sticker showing battery orientation. On the outside the Frelux logo is laser engraved into the tin. There isn’t a manual with this light, but it really doesn’t need one. I would like to see a certificate of authenticity or serial number card included, it’s pretty common in the custom knife and flashlight market.

Benjamin is an instamachineist and owns his own IT services company. His level of detail and tolerances in the parts are first rate. You can just tell that a lot of time and thought went into the design of the Synergy 1. For instance batteries don’t rattle even with the cap off because the tolerances are so tight. They just kind of glide into place. All the edges are nicely chamfered and more. All the aluminium parts are manufactured using a Fanuc RoboDrill in Benjamin’s garage in the USA.

My version here is a tumbled aluminium that’s been clear anodized. Tumbling is super consistent. Even the pocket clip is tumbled, which I like because it helps hide any scratches. The light also came with a small wring where you could attach a lanyard if you wanted.

The shape of this light is different and hard to describe without seeing it. It’s a side by side battery configuration and a little bigger then a bic lighter. The end profile of the light is almost a figure 8, with the outsides being a bit wider, than the middle. The top, has some machined jimping, almost like a picatinny rail, but much closer together and not as sharp but enough to lock in for grip. This top is a hexagon shape, with angular sides, corners are rounded over. This taller area is where the emitter is and it’s sticks out the most. The bottom area is rounded over and just has small flat on the bottom with a small area of jimping where your index finger naturally sits. When you hold it like this, your finger naturally fits over the single switch.

The rear is a separate piece, it has a single central thumb nut that keeps things together. It’s cut like a gear but with the teeth being shallow and having flats. This keeps the light together and the clip in place. The nut threads onto a small threaded brass shaft that keeps all 3 main body pieces of the light together.The tail cap itself has markings engraved on it to “Reload” and “Make Ready” to loosen, and tighten the tail cap. The edges here are machined and nicely rounded over allowing you to get a good grip and pull the cap onto the light, and tighten the nut with the other hand.

This is an older or prototype body I believe because it doesn’t feature the positive and negative symbols on the body itself. This is a nice improvement and one that basically solves the problem of knowing which way to install the batteries. I think a keyed approach would also work well.

The light is using a Nichia 219C high CRI LED, in a fairly warm tint. It’s using a double anti reflective coated lens, underneath is a small short reflector that has a mild orange peel.

The beam pattern is nice for EDC in my opinion, it’s similar to a TIR style optic but with a hotter center, and dimmer spill. For me this is great for EDC, it’s enough light to see a bit of distance but also wide enough to see around you too. For me I tend to use this type of light under desks at work, looking in the mailbox, quick walks with a dog, etc

The Synergy 1 has very recently received an updated driver that improves the UI and outputs. The new Nichia driver has the following outputs at 30 second intervals: Low 1.4 lumens, Medium 25 lumens, High 125 lumens.

High Runtime
For my runtime tests I used 2x Amazonbasics NiMH rechargeable batteries. High was a very consistent output for 55 minutes before a rapid decline the last 5 minutes. Total runtime was 61 minutes before the light turned off. This was pretty respectable for a light outputting 125 lumens.

Medium Runtime
Medium was more of what I would expect to see from an NiMH typical S discharge curve. Total runtime was about 525 minutes or 8.5 hours. Most of this was at about 65% relative output, decreases were small and smooth.

Low Runtime
Low is only 1.4 lumens so it lasted a very long time. It’s the longest runtime I have actually tested with Ceiling Bounce. Just shy of 3000 minutes, or 50 hours. The graph has one spike that I have to think is an error. The last 500 minutes or so did see a step down before the light decreased.

UI is very simple on this light, Low, Medium, and High in that order. One thing I have noticed with the updated driver is that on low, I sometimes get a very brief flash when I first turn the light on. I think this is because

How does it carry
The Synergy 1’s design is well thought out. I carry it in a right small jeans coin pocket and tend to hold it in my left hand in kind of a pistol type grip. My Index finger perfectly aligns with the milled jimping on the bottom and my thumb fits nicely on the jimping on top. This leaves my pointer finger easy to access the button to function the light.

In the small coin pocket it fits nicely, but you do notice the thickness a bit. I usually have a knife in my right front pocket, and a few other random things deeper down. Ever since surgery my phone lives in my left pocket and when carrying this light I prefer it that way. If I put my phone in the right pocket the chance to scrape or scratch the screen as I draw my phone increases which I don’t care for. Other then that it carries nicely here. For me it’s comfortable to sit in an office chair with the light in this pocket and my seatbelt doesn’t interfere in the the car. I have carried it a little in the left front pocket and don’t care for it as well there due to it being a tad wide to share the space with my phone.

*Pro’s *

  • Made in the USA with fantastic machining and tolerances. I would love to see a Made in USA (Or Flag) somewhere on it, maybe inside the tail screw recessed area.
  • While my version is clear anodized I have heard only fantastic things about the colors being offered. If I end up getting one it will definitely have some color.
  • I like how upgrades are available such as anodizing and a titanium pocket clip.


  • The switch is mechanical, it takes a good amount of force to use and is loud. I also seem to get a brighter flash before getting low sometimes.
  • Battery polarity markings, My older body doesn’t have the + and – markings that newer lights have, this would help making sure you have the orientation correct. A keyed approach would also be a good solution here.

The Frelux Synergy 1 is a fun little custom EDC light from a maker who wasn’t into the flashlight scene like many of us are. A ton of thought has gone into the ergonomics to make a unique light that feels good in the hand and pocket, while being very functional at the same time. The fit, finish and machining quality are all top notch and easily beats production lights. Version 2 of the driver only improves this light, by offering more output and a revised UI that while very simple is more enthusiast friendly, by being linear and having a true moonlight mode.

If you don’t follow Frelux on Instagram I would strongly encourage you to do so. Benjamin does a great job of posting nearly every day showing what he is working on, new products, build progress, and pre sale notification. This light is being built in batches and so far it’s been super popular, so if you want one you may have to watch closely so that you can get in when a batch drops.

Frelux has recently launched a second flashlight product the FML takes some of the Synergy 1 ideas but instead of being an EDC it’s a worklight with a magnetic base, and the light being on a flexible arm, and scaled up to run on 1X AA for an increase in runtime.

Frelux is definitely a brand to keep an eye on. His designs and ideas in the flashlight game are only getting better. I wouldn’t be surprised to see if Frelux becomes the next Grimsmo type company, growing from a garage to a shop to hiring more than one employee, and upgrading machines to produce more new designs all while documenting and sharing the process on social media. Definitely keep an eye on this company and pick up one of his designs if you into custom lights.

Acebeam H30 Headlight Review (4000 Lumens, USB-C, 21700,XHP 70.2, Red, Green)

The headlamp lumen arms race takes another step with the newest release from Acebeam the H30 Headlamp. The previous brightest headlamp I had had has been the Thrunite TH30 at 3300 lumens. The Acebeam H30 is 4000 lumens, contains a 21700 battery, and has USB-C charging and can act as a power bank. Thanks to Acebeam for sending this to me to take a look at.

Packaging & Accessories
The packaging is a compact full color retail box. The front advertises the big lumen number, USB-C and the 21700 battery. The back gives lots of stats. Inside The light came in a plastic bag on one side with the 21700 preinstalled. On the other side were the other accessories such as the headband, spare orings, and a USB A to USB-C cable that also has a place to plug a cable to charge your phone along with a warranty card, instruction manual, and certificate of authenticity. I do wish it came with an adapter tube like some other 21700 battery lights I have, so you can run an 18650 assuming the springs are long enough.

The light itself is made from aircraft grade aluminum and is hard anodized in a satin black. Starting at the left end cap, this is the one that gives access to the Acebeam branded 21700 button top battery. It’s got markings indicating it’s where the battery is and which way to twist for open and close. The knurling on the outside of the cap is more for looks then grip. Each end is spring loaded. The cap end has a large stiff spring. Threads were well greased, anodized, and square cut. The bore for the battery is not perfectly centered in the body of the light, with a bit more mass being on the emitter side. This is similar to how the Jetbeam HR30 that I reviewed this year was. The right side cap is similar in appearance however this is where the USB-C charging port lives and the cap is notated as such, again with directions. You must fully remove the cap to access the charging port. There is a little pin in the center under the clear plastic cover which must be for grounding? When the light is charging a red LED comes on. When being used as a powerbank you get a blue LED.

The central body is where the business is. On top are the two UI buttons, an orange square that is an on/off mostly, and a black domed circle. The back of the light has some shallow ribs for cooling. The front has the main emitter in the middle, It’s a big XHP 70.2 emitter in what’s a fairly shallow orange peel reflector. The front glass is just 19mm in diameter. Above and to the left and right of the main emitter are the colored emitters. On the left is red, and on the right is green. These are behind frosted plastic lenses. The front aluminum piece is held on with 3 recessed hex screws.

It may seem like a simple thing but I like that the headband on the H30 came pre assembled and ready to use right out of the box. On the outside band Acebeam is written in several places, it does contain a over the head strap too. On the inside of the band there are silicone strips all the way around to help keep the light in place on a helmet or something like that. It’s a nice step over not including any or a partial. The holder for the light itself is made of a silicone rubber. It has too large hoops that go over each end of the light when the caps are off. This is a pretty tight fit and not the easiest to take on or off, but holds firm for rotation. Pretty nice headband.

Size/Weight/Physical Comparisons
Overall length is 89.5mm, at it’s narrowest on the end caps are 29mm, and the widest at the center tube at 39mm. Weight with strap, and battery came in at 182g which makes is on the heavy side. This weight is noticeable but carries fairly well with the top head strap adjusted.

For the main emitter the Acebeam H30 uses a Cree XHP 70.2 LED in cool white at 6500k. It sits behind a piece of anti reflective coated glass, and a shallow orange peel reflector. The beam pattern is similar to other XHP 70.2 but without the donut at short ranges. It does have some Cree rainbow on the corona of the hotspot, it goes a bit warmer. As you keep going further out into the spill it cools off. It looks like a few other LED options may be coming, like a 5000k main emitter, and a Nichia UV emitter, or Nichia 219C for High CRI for the secondaries.

White is available in the following lumen spacing. 3 lumens, 120 lumens, 380 lumen, 1100 lumen. Turbo is good for 2200 lumens for 5.5 minutes then it drops down to 1000 lumens for about 2.4 hours. The light also has Turbo Max which has 4000 lumens for 1.5 minutes then drops to 1000 lumens for 2.5 hours.

White runtime had a total of 150 minutes from turbo max down to low voltage protection kick in. I saw a little more length in runtime for Turbo max, about 2.5 minutes before it decreased. The decrease is quite substantial. Down to about 25% relative output from those 4000 lumens, so about 1000 lumens. Still a ton of light for a headlamp. The light as able to maintain that 1000 lumens for the remainder of the 147 minutes. That
is a long runtime for 1000 lumens. The 21700 5100mAh battery shows it’s advantage here over an 18650. Heat was pretty well controlled. The light gets on the upper end of warmish but never uncomfortably hot when on the head.

The Red Emitter is a Cree XPE2-R2 emitter at 630nm. Red has only one mode at 50 lumens but is diffused very well. It’s runtime is 10 hours. It has no hotspot. I would prefer a dimmer red mode for up close map reading because 50 lumens is fairly bright.

Green Emitter is a Cree XPE2-G3 emitter at 530nm. It’s rated at 70 lumens for a runtime of 11h. It’s diffused very well and has no hotspot.

The H30 has 2 buttons on the top a circle and a square next to each other for UI control The Square is flat, and the circle is domed a bit. Depending on what color mode you are in the buttons do slightly different things. For normal white operating modes, the orange square is On/Off. When the light is it comes on in the last previously used mode. Use the circle to go up in mode up to Turbo (Not Turbo Max). Double click the square to go to Turbo Max (Full 4000 lumens). Triple click to go into the Red SOS mode. When in any mode long pressing on the circle (about 1.5 seconds) will go into the color modes. A short press of the round button will switch color modes (Red to Green, Green to Red), and a long press of the circle will move back to white mode at low output.
Moonlight mode is also available if you hold the square for about 1 second when the light is off. Overall the UI takes a little getting used to. I think 2 buttons make sense.

Recharging And Powerbank
*Recharging: *This light has a USB-C port under the right side cap. You must completely remove the tailcap to access the port. Maximum charging rate I saw while charging from an empty battery was an even 2A. This is great to see and speed the charging process up but it still took 3 hours and 23 minutes to charge the battery to completely full. While charging there is a red LED in the center of the light that goes solid when completely recharged. The included Acebeam branded battery is a button top but flat top cells work too, for all functions of the light. Standard USB A to USB-C cables work or the cable that’s included.

What was odd and I am seeing on more and more USB-C flashlights are that they seem to have a problem charging with USB-C to USB-C cables/power sources. The H30 is no different. I tried charging it using an Anker USB-C to USB-C cable and a couple of different charger I have that support USB-C and none work. If I used a USB-A to USB-C charger it works without an issue.

*Powerbank: *This light can also be used as a powerbank. Included was a special USB-C cable that has a female USB A port on it to allow you to plug in another cable (Not included) to charge your phone or other device. I was able to pull 2.5A from a full battery for a while, but the light is happier pulling 2A for a longer time. When using as a powerbank you get a Blue LED under the plastic cover showing which way the power is flowing.


  • Preassembled headband with silicone all the way around.
  • Pretty good heat control for such a bright light
  • Really long runtime for 1000 lumens 147 minutes)
  • Ok beam profile for an XHP 70.2, Great beam profiles for Red and Green
  • Good charge/discharge speed.


  • On the heavy side – the top band helps when on the head.
  • I would like an additional lower power red mode for map reading.
  • USB-C to USB-C charging doesn’t work.

Acebeam has built a flagship headlamp with the H30 that ticks a lot of boxes. The XHP 70.2 isn’t my favorite emitter due to the Cree Rainbow and beam pattern but if your not super picky I think you won’t mind. They have made a light that can sustain 1000 lumens for a substantial amount of time and burst up to 4000 lumens for short duration. The penalty you pay for this is weight. At 182 grams it’s on the heavy side but I got used to it, especially after adjusting the top head strap. I am glad USB-C is becoming more common on lights, and the extra powerbank feature here is a nice bonus. I think the Acebeam H30 is best for someone who needs a high output headlamp for a long amount of time, it certainly has significantly better runtime then some of it’s 18650 based counterparts.

Olight i3T Cu Mini Review and Flash Sale reminder (10/22 1-3pm EST)(Raw Copper, AAA EDC Light)

I wanted to show you the brand new special edition Olight i3T Cu in raw copper. This is a special edition of the Olight i3T I reviewed earlier in the year. Olight is having a flash sale for this light on Monday October 22nd from 1-3pm eastern during this time the light will be available for 25% off making it only about $24 plus a little for shipping. This is a great sale for a solid copper EDC light. I have only had the copper version for a few days and I like it alot. I kind of have a thing for raw copper and the aluminium version of this light gets a good amount of pocket time in my current EDC lineup.

Full Image Gallery:


If you have not seen my review of the aluminum version of this light make sure you check it out on Youtube or Reddit. Let’s quickly go through the differences in the new copper edition.


  • Only 10,000 will be made for sale worldwide, they are individually numbered so if you want one you better buy it now before it’s sold out.

  • Solid raw copper. The light is solid copper inside and out, even the tail cap innards, This means the light will take on a great patina the more you use it. It came sealed in a protective bag inside the box so that it will be perfect when you first receive it. I am really looking forward to how the patina develops over time. Make sure you subscribe to my instagram. I will be showing progress of how it naturally progresses with the patina. You do pay some weight penalty for copper but since this is a small light I don’t think you will notice much in the pocket.

  • The clip steel and is the same pattern as the aluminum light but this time it’s PVD coated in a brown/copper metallic finish. Right now when the light is bright and shiny there is some definite contrast here but as the light develops patina it will really blend in I think. Olight has also added 2 small raised area where the clip sets to give it a more snug secure fit to help it not rotate. Also changed are the color of the tail cap and button assembly. It’s also a copper brown finish.

  • Lastly the O’Ring around the lens and inside the tail cap have been changed from the standard black to red.


Outputs, UI, and the emitter in this light are the same as the aluminum version. The i3T Cu makes a nice EDC especially if you have a thing for copper, this is really easy light to pick up.

Don’t forget about the flash sale on October 22nd from 1-3pm EST on


Olight S1R Baton II Review (1000, EDC Flashlight, 16340, Rechargeable)

Today I am looking at the new Olight S1R Baton II. While the name is a mouthful this small light means business. It’s just 2.4 inches tall but produces 1000 lumens on Turbo, has a magnetic tail and has recharging via the doc. Thanks to Olight sending this to me to take a look at the newest light in the Olight flagship line.

Full Image Gallery:
YouTube Version of this Review:

Packaging follows other recent Olights. It’s a tall and narrow white textured cardboard box. Inside is a white branded plastic tray that holds the light. Underneath was a large yellow cardboard read me, telling you to remove the insulating film, suggesting to store the battery in an included battery keeper, and what all is inside. Included with the light is the light itself, the Olight dual direction pocket clip, a proprietary Olight IMR 16340 550mAh battery, new generation of the magnetic USB charger, a small plastic battery box, lanyard (With threading needle), and a brown suede bag.

The S1R Baton II follows in a long line of well made production lights. The light is made from aluminium and anodized a smooth satin black. Starting at the back of the light we notice the recharging contacts for its magnetic recharging system. The outside silver rings are slightly raised, and the inner brass button is sunk in just a little. I did test for safety of this system with a bit of steel wool and didn’t have a fire starter on hand. This tail cap is magnetic and quite strong. It easily holds the weight of the light and is better against vibrations then some previous Olights. The tail section also has a hole drilled in it’s side to allow for a lanyard.

Unlike on the original S1R Baton, on version 2 the tail and body tube are one machined piece of aluminum, and the only place the light seperates now is right below the head. The body tube has a new machined raised square with each side tapered in. It’s definitely more aggressive than the small flat squares before but nothing that should rip up a pocket. I like it quite a bit. Threads are small, well machined and greased.

The head itself is pretty small, and inside features a pretty stiff brass spring. On the exterior writing is kept to a minimum, with just a small Olight logo, and opposite that the model number and serial number in small writing. The button is the same as others in the Baton series, It has a silicone cover, and has a small red LED in the center for indicating status. This is surrounded by a blue bezel. The front bezel of the light is reflective blue, and has engraved 1000 Lumens, CCT 6500k CRI 70. It features a TIR lens.

Size and weight comparisons
I measured the length at 63mm and the maximum diameter in the head at 21mm. Weight with the battery and clip came to 51g. The S1R Baton II makes a pretty good EDC for a 16340 battery light. The thin side walls and clip make it a pretty easy carry in a front jean pocket in my opinion.

In comparison the Olight S1 Mini Baton Is 54mm in length, 21mm in diameter, 43G with battery and clip, its tail isn’t rechargeable or nearly as strong magnetically though. The Copper Smini Baton I have with battery is 54mm in length, 21mm in diameter but comes in at 72g with battery and clip due to copper being heavy.

This light uses a Cree XM-L2 LED in cool white. It’s rated at 6500k with a CRI of 70. I don’t notice any cree rainbows, or odd color tints on mine. It features a TIR style optic and it’s no secret I like this style of optic on a short from factor EDC light like this. You get a sizeable hot spot that allows it to throw a useable amount and then you get a wide spill. For me and how I use an EDC light (Shorter durations) this is about perfect.

Runtimes are about what I expected for a small light that leads off with saying it’s capable of 1000 lumens in turbo. Turbo mode doesn’t last that long, only about 1.8 minutes before it starts to slowly decrease fairly significantly to about 30% relative output. While that sounds like a lot it’s still quite a bit of useable light for about 28 minutes. Past this light steps down again pretty quickly to low mode. Total runtime from turbo on the included 550mAh battery was 65 minutes. Heat was well controlled for a small light.

The S1R Baton II has the standard Olight UI many of us have come to know, and I like with the slower fades from off/on and between modes. From off, long press to activate moonlight mode at 0.5 lumens. To turn on in normal modes single click the switch, to change brightness level hold the button and the light will cycle through the 4 available modes lowest to highest. Double click to access turbo. Triple click to access strobe. The light also features memory mode for normal modes.

Lockout can be accomplished when the light is off by pressing and holding the switch for 2 seconds until moonlight mode comes on and immediately shuts off. If you then press the button the red LED under the power button will come on to let you know your in lockout mode. To exit lockout press the button for about 1 second until moonlight mode stays on. Personally I will just give the body of the light a ¼ turn to mechanically lock it out. The light features a short 3 minute timer, and a longer 9 minute timer. If these are setup (See the included manual) the light will automatically shut off when the end of the timer is reached.

Recharging and the Battery
Olight has an updated magnetic charger (MCC2) with the S1R Baton II. The main benefit of this charger is it’s faster. It now is capable of 1A charging. The charger is also capable of working with older versions of lights such as the S30R, or S2R. On those it was able to charge at a closer rate of .95A.

Visually it’s a little different with the bottom and top having rounded edges. Gone is the LED indicator at the base of the charger and instead it has been replaced with a tiny LED on the bottom. I find the LED harder to see if it’s sitting on top, but better for night time bedlight charging due to less ambient lighting.

On the S1R Baton II the charger didn’t charge at full speed the charger has printed on it. This due to the smaller capacity of the battery. You wouldn’t want to charge this 550mAh cell at AA for safety and cell longevity reasons. The battery has a plastic separator that stands up a little more and protects the positive terminal more then other olight batteries have had. The light is also capable of using a CR123 or other olight batteries although you won’t be able to recharge it in the light.

My guess would be Olight will be rolling out updates to some of their other Baton series lights with this new charger over time.

This is the 4th model of Olight magnetic chargers that I have, I think I need to start putting labels on them to keep them straight in my charging drawer.It would be nice if they had labels or color indicators on the lights/charges to help you out.

I deliberately tried to short circuit the exposed charging contacts on this light with a bit of steel wool and had no ill effects.


  • Small size, well built, strong magnet, great pocket clip.
  • Convenient slightly faster charging
  • Simple interface


  • Proprietary battery, new to the this updated light. The older ORBC-163C06 also works in the light but won’t recharge.
  • MCC2 charger with the LED on the bottom makes it harder to check status, I would prefer the charge status on the side.
  • LED choice, while I don’t have major complaints against the XM-L2, I would love to see a neutral white or high CRI option, it would make this fantastic EDC in my opinion.

The Olight S1R Baton II is a nice little EDC light with a lot of power for a short time. I think it’s a nice update. I especially like the new style of pocket clip and the new milling on the body. Olight does a good job with TIR reflectors creating attractive beam patterns for this style of light in my opinion. If you are needing a new EDC this is a nice option to choose.

Nitecore MH12GTS (1800 Lumen, 18650, 1” Tactical)

The Nitecore MH12GTS is the upgraded version of the popular tactical MH12GT. It features and upgraded LED, 1800 lumen max output, microUSB charging, and an included 18650 battery. Thanks to the for sending this to me to take a look at.

Full Image Gallery:

The YouTube version of this Review:

This light comes in a Nitecore standard black and yellow retail box. On the outside there is quite a bit of info on the light. On the inside the light sits in a plastic tray with all the accessories and manual underneath. Included accessories are the light itself, lanyard, microUSB cable, pocket clip, tactical ring, NL1835HP 3500mAh button top battery extra orings and a velcro pouch.

The Nitecore MH12GTS is made of machined aluminum and his hard anodized a mostly glossy black. Starting at the tail cap, it has large lanyard holes on either sides, and does tail stand. The sides are cut down to allow for a finger or thumb to access the off center silicon textured button. It’s a pretty stiff button for a full click and mechanical. Opposite the button is a flat facing port cover for the USB charging port. The cover stays in place pretty well. The USB port underneath is waterproof and I will test that later in the review. Spring inside the tail cap is stiff and dual construction

This uses a dual tube style construction, from what I can tell the inner tube is not removable. Threads are a steep ACME cut and unanodized at top. The tactical ring on this light is threaded. I like this and means that it won’t’ freely spin like happens on many other light designs with a similar ring.There is an oring above the tactical ring.The body tube has smooth knurling but has horizontal lines milled in to break this up and then for the flats where the labels are they are milled a decent amount lower. This provides a bit more grip. The body tube looks like it’s removable but I can’t get it to budge. Further up the light has an anti rotation ring that’s small.

The head of the light has minimal heat syncing and heat hasn’t been a major issue here because the light does step down. The button is metal and has a clear Status indicator ring around it with a blue LED underneath. The head is pretty smooth. The bezel is smooth and the glass is anti reflective coated. The reflector is fairly deep for a 1 inch light and the LED is nicely centered.

The pocket clip on this light slots in right below the tail clip on the body tube. My first clip didn’t fit very close to the body of the light. I contacted Nitecore store and they promptly sent me a new one which was a much better and closer fit. I would prefer a clip that allows for deeper carry personally but this seems to not be what is done on most lights similar to this one.

I measured length at 144mm. Maximum diameter is 35mm at the tactical ring, max diameter of the body is 26mm. Weight with the battery and pocket clip is 153.1 grams.

Size comparison with the Olight M2R Warrior is that they are very similar in diameter. The light is shorter at about 15mm. The nitecore is slightly lighter.

This light uses a Cree XHP35 HD LED in cool white. It’s capable of producing upto 1800 lumens in turbo mode. It throws pretty well due to that deep reflector. Overall the beam has a hot center and about 4 distinct rings. It’s not a very smooth transition to spill. The brightest hot spot has a bit of discoloration in the very center. This is easily noticed straight on against a surface that’s all the same texture and color such as drywall or concrete. It’s noticeable at distance as well.

This light is capable of running on 18650’s, CR123a, and RCR123A. 2× 18350’s is not recommended due to too high of voltage. To access Turbo you need cells capable of 8A or more. Total runtime with the included 3500mAh battery was 142 minutes. Turbo run time starts decreasing almost immediately. It has a run time of about 3 minutes. When the light steps down you are getting about 45% relative output for about 20 minutes. Between 20 minutes and 142 minutes the light is pretty stable between 45% and 35% relative output for 120 minutes. Heat is pretty well managed.

Turbo Runtime

Full Runtime

One thing worth noting is that the manual says “When using an IMR 18650 battery and the power level is low please stop using the product when the power level is low to prevent damage to the battery. An IMR battery is what the light ships with. This suggests that the light doesn’t have low voltage protection for this type of battery built in, so using protected cells would be a good idea. Lucky the one that ships with the light is protected.

The tail switch on this light functions as only an on and off. It takes a decent amount of force to press, I think this is good for a tactical light.

For normal operation this light has 5 modes, UltraLow, Low, Mid, High, and Turbo. When the light is on the mode button cycles through them. Memory mode is strong on this light and works everywhere except strobe.

Momentary access to turbo is possible if the light is on by holding the Mode button for 1 second, if you let off it returns to what mode you were in previously.

Strobe on this light isn’t at just one rate. It’s pretty fast and then alternates between fast and really fast. I like it, I just wish strobe wasn’t so easy to access with just a double click of the mode button. When in st4robe you can also get to Beacon or SOS by long pressing on the mode button. To exit a special mode just short press on the mode button to return where you were previously.

Direct access to moonlight mode can be accessed with the light is off by pressing and holding the mode button, while actuating the tail button, so it’s a 2 hand operation.

This light has recharging via microUSB on the tail cap of the light. There is a rubber flap that protects the port from dust and moisture. The port is also conformally coated, so it’s protected from moisture even if the flap is open. To test this I dunked it in water and then blew some air in the port with my mouth and proceeded to charge it without issue. There is also a small blue LED built into the tail cap to show charging status. Blinking blue means it’s charging, solid blue means it’s full.

The disappointing thing about charging via USB on this light is the speed. I saw charging speeds at it highest at only 0.64A. So for the included 3500mAh battery that means a full charge took me 10 hours, 9 minutes. This is really slow in 2018 for a premium light. I would expect a minimum of 1A these days, if not closer to 2A to cut down on the charging time substantially.


  • Comes with a nice high capacity Nitecore battery
  • Waterproofing even with the USB protective cap off
  • Quick access to ultralow 1 lumen mode


  • Slow onboard Recharging .64A means using onboard recharging takes forever.
  • Beam throws well but has a slightly more dim area in the direct center.
  • Not a big fan of double click to strobe, I would prefer double click of the mode button to go to turbo and triple click for strobe.

The Nitecore MH12GTS is a pretty nice tactical style light with a good amount of throw for its compact size. The UI takes a little while to get used to but if this was a light you used often I think most would like it. I like how it’s able to use a pretty wide variety of power, including primary and flat top unprotected 18650’s. I like that Nitecore has put a lot of effort into making the USB port waterproof. I can get past the beam irregularities in normal everyday use, but the slow charging time is hard to live with on a premium light. Overall it’s a nice showing here from Nitecore and one that will be especially useful for a nice throw in a small diameter light.

Amutorch AT40 Review(Titanium, Quad Nichia, 18650)

The Amutorch AT40 caught my eye because it was made of Titanium, had quad Nichia LED’s, used an 18650 battery, and a screwed on deep carry pocket clip. This light has a few things going for it and some negatives too. Thanks to Banggod for sending this too me so I could investigate it further.

Video version of this Review:


Packaging is very basic at best. It’s a brown generic cardbox. Inside is some foam fit for the light, and couple of extra o’rings, and rear button. The manual is all in Chinese.



The basic and simple design of this light as well as being made in titanium is what grabbed my eye on this light. Starting at the back the clip is screwed on to the very top ring of the light, using 2 T8 Torx screws. I like the clip design on this light, it’s deep and pretty sturdy. The button is a loud mechanical fairly stiff switch but it’s recessed a little. Accidental activation isn’t an issue. Threads are square cut, and came with a decent amount of grease.


The body tube is a tumbled titanium finish and has cylindrical machining rings in it for the grip. It’s subtle but nice. The head is made of what looks to be a different material then the rest of the light. Not sure if this is titanium or another material


Disassembly of this light is very simple. Nothing was glued in place. The only trick is to unscrew the rear ring you need to first remove the clip. I used some strap wrenches to tighten and loosen the rear bezel.


I used this light to try some heat anodizing of titanium for the first time (I went a little further then I wanted). This went moderately well and I will probably attempt to redo the front ring and do the body tube as well. It’s important to make sure you wipe it down one more time right before anodizing.



This light uses 4x Nichia 219C LED. They are in a neutral white color. The beam pattern on this light in it’s stock configuration isn’t pretty. It’s rather square with rounded corners and has artifacts. It’s convex lens means its pure flood, with no hot center. I personally don’t care for this type of lens, I find it less useful and prefer some spot or TIR options.


Heat is a pretty major issue with this light, I measured the surface temperature of the pill at 140F which is hot enough to burn you. The light stays quite warm even in it’s medium mode. The pill area gets the warmest and pretty quickly but it doesn’t take much time for this to radiate to the rest of the body.



For my runtime tests I used a 3000mAh Sony VTC6 battery. This light only works with unprotected flat top cells. The top runtime (About 2000 lumens according to the listing) is good for about a declining 5 minutes. Between 5 and 10 the light steps down to about 65% relative output where it sits fairly comfortably for the next 60 minutes. Total runtime was about 100 minutes. The last 30 or so minutes the light goes into low power warning mode. It slowly fades out then fades back on.



UI on this light is 3 simple modes, Starting in high, then to medium, and then to low. It has memory and will remember the last mode you are in. I don’t see this as a tactical light so I would prefer it start in low, go to medium and then high.



  • Pretty affordable titanium quad host.
  • Awesome, custom like pocket clip
  • Nichia Emitters
  • Decent option for modding, I hope I can find an optic that will fit.


  • Stock convex lens is pure flood with an odd beam pattern and artifacts
  • Extreme Heat
  • Only flat top unprotected batteries work.
  • I have read about some DOA units on other forums although I didn’t have one
  • I wish it started in Low mode first.



I think of this more as a project light rather than an everyday user, or EDC. I personally don’t care for the convex lens it ships with and the squarish beam pattern it creates. It’s basically a big flood. It doesn’t appear to not have any thermal controls which means it gets dangerously hot for extended runtimes. I like that it’s made of titanium, and can be flame anodized pretty easily. If I am able to find a different optic or reflector for this light I think I will like it quite a bit. If you do decide to get one make sure you mechanically lock it out as an added layer of protection against burns.

[Review]Lumintop GT mini (18650 Thrower – Mini Giggles)

For the past few years forum members have been designing a huge thrower flashlight called the BLF GT, an 8× 18650 thrower. Lumintop was the manufacturer, and it was a great success, but very pricy. Lumintop decided to make a much more reasonable, smaller, and more affordable version which I have here today to review. The Lumintop GT mini takes what was learned from the BLF GT and shrinks it to a light capable of 1200 lumens and a throw out to 700+ meters, in an easy one handed pocketable light. Thanks to Banggood for sending this to me to take a look at.

Lumintop typically has nice packaging and the GT mini, is no different. The brown box had an outer brown cardboard sleeve with a line drawing of the GT mini, the inner box just has the Lumintop name on it. No info on this light is listed externally other then if it’s Neutral or Cool white with a sticker on the end (Probably from Bagngoogd). Inside the light is packed in form fitting white foam. Accessories that came with my light were 2 extra o’rings and a purple unbranded lanyard. I prefer the orange lanyards that Lumintop used to use. A short 18350 tube is also available for this light. It’s a $5 extra to get it separately or get order it from the beginning for a few extra dollars.

Lumintop does a nice job with their lights and this is no different. It’s made from aluminium that’s been hard anodized in a near mat black. Threads feel nice, although they were dry from the factory. The tail cap is flat, but indented in the center. It looks like you could fit a thin magnet in if you desired. The lanyard hole is small as well but that’s not a major issue. The tail cap has 6 small flat areas to aid in grip. The light includes dual springs in the tail cap. Threads are fine, and have a slightly flat profile on top.

The body tube has flat diamond knurling that’s medium grip. It has some concentric areas turned in it to break up it into 4 blocks, and then 4 flats milled into it for writing and orientation. The spring on the head is short, stiff, and single :). There isn’t any physical reverse polarity protection on the head. The head itself has a series of rings with varying degrees of depth of cut to dissipate heat. The button has a silicone rubber feel to it and is slightly raised. Underneath is a LED that has various functions. The rest of the head is relatively smooth with small cuts for style near the edge. The reflector is deep and smooth. The LED is nicely centered. The front bezel is lightly crenelated and is not glued on. The lens is anti reflective coated.

My only build complaint is that the flats on the body tube, where the labels are for the light don’t line up with the power button when screwed all the way down so that the light is operational. Aesthetically this bothers me, but it’s also a small operational thing as well because I like the flats to line up with the button because it’s easier to find the button in the dark. Since this light by default has a lit up button it’s less of an issue. It seems not all the lights are affected by this by reading on Budget Light Forums.

Size/Weight/Water Rating/Size comparison
I measured length at 132mm, width at it’s largest at 50mm, and at it’s narrowest 23.3mm. Weight with an 18650 battery is 200 Grams. The light is rated for IPX68.

In comparison to other throwers, The GT mini is the same length as the Thrunite Catapult V6 but the head is head and body tube are smaller. Compared with the Convoy C8+, the GT mini is a good deal shorter (no tail switch), and has a slightly larger sized head.

This light uses a Cree XPL HI LED and is available in cool or neutral white. Mine that I am testing here is in neutral white which is my preference. This is pretty warm for neutral white which I don’t mind. Probably around 3800k or warmer. It uses a FET driver to achieve around 1200 maximum lumens in Turbo mode.

For runtime I used a 3400mAh Protected Thrunite battery. Step Down was pretty fast and pretty agressive on this light. It really stepped down pretty low and quickly after 2.5 minutes. It stepped down again at 3.5 minutes to 10% relative output. This is great for thermal and overall runtime but less practical for actual use. It requires you to either bump up again repeatedly to get brighter levels. Overall runtime was over 300 minutes but this was at about 10% relative output. Heat was not too bad, the head got to about 105F.

This light uses the popular NarsilM V1.3 firmware. I won’t pretend to be the expert on this firmware as it offers a lot of options. It’s a firmware designed by enthusiasts for enthusiasts. What I like about it on this light is that it’s ramping, meaning the light doesn’t have predefined levels by default. This can be switched if you don’t like ramping but I will stick with the default for this review. The manual does a nice job of explaining the firmware. Full ramp from low to high is about 2.5 seconds. The light flashes at the top and bottom to let you know where it is. It has a shortcut to turbo if you double click. If you double click again from turbo you get into the strobing modes, and double click to exit. The switch has a green LED under it, this is on when the light is off, but not when the light is on. This can be turned off with turning the light on and off in rapid succession. Battery status, and lockout are also available, as well as momentary. It really is pretty much all here including setting the UI back to factory default. Make sure to give the manual a read or two to make sure you have a grasp of the capabilities.


  • The Neutral white version is a pretty warm tint which I like.
  • Lumintop have a nice build and packaging quality, on par with an Olight or Acebeam.
  • Glowing power button
  • Manual is different (in a good way vs the standard ones from Lumintop)
  • Great value thrower
  • Small 18350 tube available and included in some versions of this light.


  • The body tube has flats, with labels and they don’t line up with the button, this is annoying to my “OCD”.
  • Large and Aggressive stepdowns in the runtime
  • Large head, small body tube makes it a little less ergonomic. I imaging this is even more so with a 18350 tube (Disappointed on isn’t included).

At the current sale price (With coupon) this is a high value thrower light. Unlike it’s big brother the BLF GT, the Mini is affordable, and easily fits in one hand. It offers great firmware, good build quality, and a long runtime even though it steps down a little fast for my liking. With the 18650 body tube it fits fairly well in the hand, but I can imagine the 18350 tube will be a little weird to hold on to, and get fairly warm to hold. That said I will probably buy one because of the novelty factor on my next Banggood order. With all the new throwers out this year, the GT mini ranks high on my list because of it’s firmware and neutral white options and that its been heavily influenced by enthusiasts.

Haikelite SC26 (26650/26350, ramping UI, CW/NW, Body Color Options)

The Haikelite SC26 is a new light utilizing the 26650 battery format as well as the hard to find 26350 battery size with the included optional tube design. It comes in 5 different exterior colors and 4 LED options. Thanks to Banggood for sending this to me to review. Let’s take a look at this interesting light.

Full Image Gallery:
YouTube Version of this Review:

Packaging is pretty basic, It’s a brown cardboard box, with a Haikelite sticker on the top. Inside is foam that is cut to the light’s shape. Included accessories are the 26350 tube, 2x orings, pocket clip, and manual. The manual is 1 half sheet of paper with a few technical details printed and operating instructions.

The light is made from Aluminum alloy, and is available in 5 colors of anodizing, Blue, Silver, Black, Teal, and Tan. The anodizing on my Blue SC26 doesn’t match. It seems the body tube is the outlier as the battery tubes, and end cap all match pretty well. The tail cap is small and has smooth rounded edges. Inside is a very stiff large spring. The body tube is what you would expect with orings on each side. Knurling is in a diamond pattern but not super aggressive.

A clip does come on this light but it only fits well in the larger configuration, lens up carry. Due to the thickness of this light I don’t consider it a front pocket EDC, it would be fine in a jacket pocket. I would have liked to see a spot for a lanyard but it does not have one.

I measured length with the long tube at 124.4mm, with the short tube it was 85mm. Diameter at its greatest is 35.3mm, and 32.1mm at its narrowest. Weight was 211.3g. No water rating is given but it has o’rings and seems reasonable for most uses.

With the short tube it’s pretty similar in length to a Emmisar D4 with the 18650 tube. When the SC26 has the longer tube its about 1/4 “ shorter then the Thrunite Catapult V6.

This light is using a Cree XHP35 and is available in the HD or HI variants. Mine is the HD variant in neutral white. The beam in this light has quite a bit of Cree Rainbow effect, for me it’s most noticeable in the hot center of the light. There is a definite donut, even at a distance, I find the direct center to be the warmest white, then there is a slight ring on the outside of the center that is brighter before the light fades to flood and the tint cools off. I found this more noticeable in the non turbo modes

For my runtime test I used a 4500mAh KeepPower protected 26650 battery. Overall total runtime was impressive at 350 minutes from turbo. This long runtime distorts the graph a little as nearly all that time at about 30% relative output which is somewhere near 700 lumens. When the power gets low the light does some flashing of the emitter to let you know it’s about of of power. Turbo lasted for just about 1.5 minutes before step down with my battery. Turbo mode is thermally controlled but with a timer too. Thermal mode is configurable. I used a fan to cool the fan during my short runtime test.

This light has a ramping UI which I like. It flashes to let you know your at the bottom or top of the range. Ramping UI is listed at 21 to 2050 lumens. To get to turbo when the light is on just double click. Double click again to go back to the previous level you were at. To adjust your ramping level just press and release when you want to stop. To decrease output do the the same. The light also offers configurable thermal protection between 44 and 55 degrees Celsius.

The light also offers a 5 group mode UI that you can switch into. Make sure you check out the manual or the Banggood product listing on how to configure this and all that’s offered. There is only one mode that has strobe.

The light does have lockout in the UI. When the light is ON double click followed by a long press to lock out the light. Repeat to unlock. This is not my favorite method because with the ramping UI you are long pressing a lot. So it’s easy to put the light in to lockout if you double click to shortcut to turbo and then want to adjust down.

This light is able to run on 26650 batteries which is what I did my testing with. I used KeepPower 4500mAh protected batteries. It can also run on 2× 26350 batteries or with the included short tube 1× 26350 battery. I like the look of it in the short chubby design, the problem is finding high quality 26350 batteries. They do exist but they are hard to find and of unknown brands. MTNElectronics carries some but the brand is not mentioned and they have no reviews. This was similar to just about everything else I found including Banggood. I don’t like the safety aspect of using lithium ion batteries from an unknown, unlabeled manufacturer. Hopefully some 26350’s from a known manufacturer will hit the market if this size becomes more popular or I can get some of these unlabeled 26350’s to test with this light. It’s also worth noting the light has Battery level indicator via the switch. Greater than 3.6V it will be blue, Less than 3.6V it will flash blue and below 3V it will red flash.


  • I like that the light has 5 color choices and 4 emitter choices including neutral white.
  • Ramping firmware and backlit button, it could be faster and have Lockout revised.
  • I like the size and feel in my hand with the large side switch.
  • Large stiff springs, but slight left to right rattle.


  • Sources for high quality 26350 are pretty slim. It’s not a popular sized cell.
  • Non Uniform color anodizing.
  • Mine came with fingerprints on the inside of the lens, I was able to easily disassemble and clean it.
  • No lanyard loop.

This light is advertised as an EDC, at least for me it won’t be used as a front jean pocket EDC, because that 26650 is just too big in diameter and I don’t like lens up carry with the clip, but I could easily see throwing this in a jacket pocket or bag. I like that it comes in a wide variety of colors as well. I wish 26350 batteries were more widely available because I like the small size in the hand with she short tube. Even in it’s longer configuration I like the size of this light because of it’s narrow profile for a 26650 battery. I wish it had a lanyard loop on it but even without one it’s a pretty nice light if you don’t mind a bit of Cree Rainbow.
Banggood would like me to mention that this light can be found on their site (Affiliate Link) and they have provided a coupon code of “ef3048” to get the light for $42 if you are interested in it.
