Klarus XT11 GT Pro Review (2000 Lumens, Cree XHP 35 HD, USB-C,18650)

Today I have a newer light from Klarus the XT11 GT Pro. This is an update to a light that Klarus has made previously. Klarus (Affiliate) sent this to me earlier in the year for review, and I appreciate their patience as it took me a little while to get to it.

Pickup the Klarus XT11GT Pro at Amazon https://amzn.to/2MqwsgY

 

Construction

The XT11GT Pro is made from aluminum and is anodized in a smooth medium gloss black anodizing. Visually it’s different then the standard XT11GT. It features the same tactical tail cap, with the large center button being a mechanical switch with a grippy silicon cover and the paddle on the side to allow for mode selection. The paddle was upgraded to aluminum here for incredibility. The clip is a clip on, non fixed and rotates around the body of the light. It’s not deep carry with it leaving about 32mm exposed from a pocket. 

The body is milled with small horizontal lines going around the body of the light and then it has small relieves milled in. It’s a nice change from traditional knurling and provides a good amount of grip. The threads are nice and square cut and it’s a dual wall construction. The head and body tube appear to be once piece. As we get to the head of the light it grows in size, It’s got a built in anti roll ring that adds some style and nicely disguises the USB charging port cover. This is definitely one of the better designs I have seen for this. 

The bezel is a little aggressive and the outer edges have some sharper sides. It’s a gunmetal color and stainless steel I believe. It’s easily unscrewed by hand. Inside is a anti reflective coated glass lens, a fairly deep smooth reflector 

 

Size and Weight

I measured the length at 139mm, minimum diameter on the body at 25mm, maximum diameter on the head at 35mm. Weight with the included battery and clip was 169.2g. 

For an 18650 light it’s a little on the long side, but that’s not unexpected with the deeper reflector. Here are some comparison shots with the light and some others.

 

Retention

Your 2 Retention methods on this light is with the included pocket clip. Unfortunately this isn’t deep carry carry with about 32mm of the light exposed if you do decide to use the clip. With the size of this light that’s ok, as I think it’s more of a bag or coat light myself. The included holster does the job pretty well too, no complaints there. 

 

LED & Beamshots

The XT11 GT Pro is using the Cree XHP 35 HD LED in cool white at 6500k. This is an interesting choice of LED”s since it’s officially been discontinued by Cree. That said plenty of existing stock still exists and Klarus must feel like they have enough to meet the expected demand of this light. The beam it’s self is a good all arounder. The deep smoother reflector means the light has a fairly small hotspot and it throws pretty well but there is also spill to allow for short and medium range light. So a good all around beam. 

The light will run on 18650 batteries which is how I will use it, but it will also run on 2x CR123a batteries which is nice as a backup. As a result the working voltage is 2.8V to 6.4V/ No PWM was observed. 

 

Runtime & Heat

I measured runtime with the included 3100mAh battery. Turbo runtime was 50 seconds before stepping down to 90% and then it ran for another 2 minutes 10 seconds before settling at 30% relative output where it ran for an additional 1:37:00. Total runtime was 2 hours. Max Heat I saw was 42C at 1:35. 

 

UI

Like many of Klarus recent lights this has 2 modes of operation, a Tactical and a Outdoor setting. The tactical mode allows the main button on the rear of the light to go to turbo, and the paddle to be a shortcut for strobe that you can lock on by holding for 2 seconds.

I primarily tested the light in it’s outdoors setting though. When in this setting the primary button on the rear is a shortcut to turbo both as momentary or locked on. Once on you can use the paddle to decrease the modes from turbo, high, Medium, and low. You can also use the paddle when the light is off to start in moonlight mode and then increase in output for each push. It’s a system that works better then I expected and is pretty intuitive once you use and get it.  

 

Recharging

One of the updates the XT11 GT Pro has is USB-C charging. Unfortunately it doesn’t support USB-C to C or USB-C PD charging. So you need to use the supplied (or similar) USB-A to USB-C cable to charge the light. The port cover here is nicely shaped and fits well into the side of the head. It’s one of the better executions I have seen of this in 2020. 

I charged the included 3100mAh battery from LVP to full in a total time of 3:23:10. It wasn’t the fastest charging rate, as the maximum I saw was right at 1A. There is a small LED indicator light built into the side of the light to act as a battery charge state indicator. Green is anything more then 70%, orange is between 30-70%, and red is less then 30%, red flashing is less then 10%. 

Packaging

My light is a super early production light (Serial number 17), and doesn’t have a box so I can’t comment on that. I can tell you the accessories it came with. My light came with a 3100mAh button top protected IMR 18650 battery, a Klarus branded lanyard and a USB-A to USB-C charging cable. It also came with a nylon, Klarus branded holster. It has a Dring and velcro belt loop. It seems to be solidly made. 

 

Pro

  • I like the outdoor UI setting here once you get the hang of it but it’s a little different.
  • Nice size in the hand for an all around light if you want your buttons on the rear.


Cons

  • Seems expensive
  • Cool white only
  • No true moon light mode, lowest is 10 lumen output
  • No USB-C to C compatibility and slow charging

 

Conclusion

My conclusion for the Klarus XT11GT Pro is that it’s a good all around light general purpose light. The 2 UI modes allow you to use it tactically if you want or use it in the outdoor mode which is more appropriate for everyday uses like power outages and camping. The beam is useful with enough throw and spill to do both jobs pretty well. What I don’t care for is the asking price I am seeing at the time of filming. It’s high in my opinion currently. Around $50-60 would make it a good value but at nearly double that I would struggle to pay full price. So if you’re interested I would watch for a sale or coupon. 

Acebeam L17 Review (160,801 Candela, 1400 Lumens, Awesome Thrower)

Today I have a new compact tactical thrower from Acebeam. They boast that the L17 which easily fits in your hand will throw out ot 802 meters. It runs off an 18650 and features a Osram LED. Thanks to Acebeam for sending me this new model. Let’s take a detailed look.

Packaging & Accessories

The light does come in 3 different versions, a white or Green LED version both capable of 800 and 820M of throw respectively, and a Red LED version that’s capable of 460M of throw. T

The standard package is a nice retail box with a line drawing of the light and the LED lumen and distance ratings on the box. On the back side there is a lot of stats and detailed info, good for any retailer looking to sell this. Accessories that are included is the light with the clip and tactical ring installed on the light. It comes with a lanyard, spare button cover and 2 spare orings as well as the standard paperwork and manual. You also get a nylon holster that’s branded Acebeam that has a D ring and belt loop with a button. 

Acebeam offers a couple of additional accessories on their website that will work with the L17 but are not sold in the standard version. First is a 10A rated 18650 battery with microUSB charging and a remote pressure switch for only $10 which is a good price. 

 

Construction

The L17 is made from aluminium and is hard anodized in a flat black. In the tail is the e-switch for the light and it’s truly silent. The cover is a rubber boot that has medium texture that sits just under the bezel. Internally, the tail has a single stiff gold coated spring and then an additional contact to the inner tube of the light. Threads are anodized, square cut and smooth. 

There is a tactical ring on the body which serves as a cigar grip point, the lanyard attachment point and adds reinforcement/lock for the clip on pocket clip. Both the tactical ring and pocket clip are removable should you wish. It’s a nice way to add quite a bit of security to the clip without making it permanent. The body tube itself is plain and features no knurling, I would like to see a little more grip here or closer to the head. 

The head itself is glued to the body. The head has some decorative milling around it and it helps dissipate some heat. The bezel is aluminum and has some modest large crenulations for a tactical light. The lens is glass with a Carclo TIR lens inside designed to enhance the throw. 

Size and Weight

I measured the length at 140mm, minimum diameter of the body tube at 25.5mm, and maximum diameter of the head at 40mm. Weight with an 18650 battery is 196.9g,

 

 

Retention

You have a couple of retention and carry options with the L17. It does come with that nylon holster for belt carry. It’s a basic holster but does the job well. You also have that pocket clip. The clip is 1.4 inches from the top of the light so it’s definitely not deep carry. 

LED & Beamshot

Acebeam doesn’t specify which LED exactly is in the L17 only that it’s an Osram. I asked my contact for clarification and they said it was an Osram KW CSLPM1.TG which is a mouthful but good to know exactly whats in it. It’s a very throwy LED that Acebeam has put a TIR optic on top with a glass lens. It’s different looking than your traditional optic and this is designed for all throw. 

The result is a light that has virtually no spill, it’s all focused on the center in a tight pattern. The combination of the optic and LED choice explain the claimed 160,801 candela rating here at 1400 lumens in Turbo mode. Tint here is cool white but I don’t detect much blue in the beam. In my night shots it stands up pretty well to some of the competitors using different LEDs but this has a tighter more focused beam. I didn’t notice any PWM here.

Specs below are for the White Version I have. The Green version throws slightly further. 

  • Turbo – 1400 Lumens – 160,801 Candela
  • High – 370 Lumens – 42,025 Candela
  • Mid – 150 Lumens – 23,409 Candela
  • Low – 50 Lumens – 11,025 Candela
  • Ultra Low – 15 Lumens – 3,600 Candela

 

Heat & Runtime

I did all my runtime and heat tests with the supplied (optional) Acebeam 3100mAh battery that was sent. It’s a 10A battery so keep that in mind for what you decide to put in this light and choose something with at least htis rating. Total runtime was 4:35:00. In my runtime tests I saw Turbo last for 3:30 before stepping down to right at 50% relative output. This is also where I saw maximum heat at 64C (147F) so this definitely gets hot and that thermal protection kicks in to limit output. The light maintained this 50% output for a total of 1 hour before stepping down again to about 4% relative output. My advice would be if you plan to use this light on Turbo for more then once past step down is to wear gloves. It only takes exposures above 60C for more then 3 seconds to get 1st degree burns.

 

UI

The L17 uses a pretty traditional and simple interface. When Off long press on the rear tail switch for ultra low (15 lumen), single click to turn off. Single press to turn on to low, long press to cycle modes. Double click to go to turbo, and triple click to go to strobe. 

 

I will say mode spacing here isn’t super common. Ultra low is 15 lumens and throws really well for not much light. Next is low at 50 lumens, Mid is 150 lumens, high is 370 lumens. Acebeam says this will go 410 meters. Next is Turbo the full 4500 lumens or 160,801 candella. 

 

Pro’s

  • Nice to see colored LED’s being offered here instead of just a filter. I could see this being popular with a hunter with the green tint option. 
  • Very tight and compact beam with great throw
  • A fairly compact bezel which makes this more accessible.
  • Silent Tail Switch & good vibration resistance.

 

Con’s

  • The light gets incredibly hot during turbo before step down. Wear some gloves or hold the back of the light.
  • Big steps between High and Turbo. 

 

Conclusion

I can recommend the Acebeam L17 if you’re in the market for a fairly compact 18650 powered thrower with basically no spill. I am typically not a big fan of tactical lights but the UI on this light is pretty non-tactical so it works out well. 

 

This isn’t the light to take with you when hiking, or for EDC or for walking the dog to see right in front of you. It would be great for a security guard who was needing to point out a specific spot on a house or inspect something from a distance. It’s also just a lot of fun to impress your friends or significant other, it’s a lot of power and so focused. It’s probably the next best thing to a LEP light.

Klarus E2 Review (1600 Lumens, 18650 deep carry EDC)

Today I have Klarus’s new Deep Carry EDC light, the E2. This is the second light in the Klarus E series, and I reviewed the E1 last year. Make sure to check the description for a link to that review. This light is designed with EDC in mind to minimize the size of an 18650 light while providing a good amount of output and features. Thanks to Klarus for sending this to me to take a look before it’s widely available. 

 

I am trying to grow my instagram followers so I can share links to things in my stories so if you’re not a follower please go follow me @Liquidretro and as always I appreciate you liking this video and giving that bell icon a click if you like these videos on YouTube too.

Packaging

Packaging is a nice white Retail box with a red hanging tab. It has a photo of the light on the front, with the model number prominently displayed.On the back and side there are stats about the light and a chart telling more specs.

Inside the package you get the following. The light itself, along with a Klarus 3600mAh 18650 battery, deep carry pocket clip, lanyard, extra o’ring, micro USB charging cable, and small gray felt bag. 

 

Construction

The Klarus E2 is made from Aluminium and hard anodized a semi gloss black. It’s a nice fit and finish as recent Klarus lights have been. The tail and body are all the same as the E1 had. Starting at the tail cap, we have a dual switch design. The main switch is a larger round button that sits up somewhat proud, next to it is a paddle that acts and the secondary switch There is half a shroud built up around the larger button on the outside, to help it from getting pressed accidentally, and it’s the lanyard attachment point. This is nicely styled and works well from my experience but the downside is it’s not magnetic and it can’t tail stand. 

Threads are anodized, acme cut, and fairly small. There are springs on both ends of the light, and a dual ring system in the head like we saw on the Klarus XT21X. The body section of the light has concentric rings milled into it which gives some grip but not a ton. The head of the light is one piece with the body, in fact the entire diameter of the light is the same. There are no buttons and only minimal labeling. In my example the laser engraved serial number is not straight. The clip fit’s up on the head, and does rotate around, it can be removed if you wish. Up near the very top there is a very small tricolor LED on the side of the light that’s used for a power indicator and when changing UI modes. The front of the light unscrews in theory, and under it is a plastic lens I believe. Under that is the reflector which is similar to a TIR style optic. As a result you can’t really see the LED underneath. 

 

Size & Weight 

I measured the length at 115mm, and the diameter at 23mm. Weight with the included battery and clip was 110g. 

 

Comparisons

When compared to the E1 the E2 is 8mm longer, and the same diameter. For me for the lights I own, the Olight S2R II and S30R III, both being small 18650 lights with TIR style optics.. Diameter wise they are identical. 

Retention

The light carries in my front pocket really nicely. It’s an incredibly deep pocket clip that can also be used to attach to the bill of a hat to use as a makeshift headlamp in a pinch. Being a head up carry, it does require you to flip the light around in your hand to turn it on without having a side switch. I found this a little awkward and I think I prefer a side switch for this reason on this style of light but it was a minor complaint. The slim diameter, relative shortness, and deep carry pocket clip make for a comfortable EDC in my testing. 

 

LED & Beamshot

The Klarus E2 receives an upgraded LED and outputs from the E1. It’s using a Cree XHP35 HI LED in cool white. No tint data is given but it’s not crazy cool. The beam here is nice out of the TIR style flat optic, you get a hot center thats a majority of the light with minimal diffused spill and it throws further then you think with Klarus quoting 190 meters of 9025 candela.

  • High 1600 lumens
  • Medium 400 lumens
  • Low 100 lumens
  • Moon 8 lumens
  • Strobe 1600 lumens
  • SOS 60 Lumens.

 

Runtime & Heat

For my Runtime and heat tests I used the included Klarus branded 3600mAh battery. The lights high output of 1600 lumens began stepping down from the moment it came on and it was down to 46% of relative output at 1:10. This is an a much faster decline then I expected. The light does have some active thermal management and the light increased slowly over the next 4 minutes to 62% relative output before decreasing again around the 8:30 mark down to the 46% relative output. From here it sat pretty flat out to 10% relative output at 2:40:00 mark. Just before LVP kicked in on the light at the near 8 hour mark it did gain in brightness the last 20 minutes by 6 relative percent. You notice heat quickly on this light in high mode, the hottest I saw was 51.9C at the 45 second mark.

 

UI

UI on this light is the exact same as the E1 and controlled all with the switches in the tail cap of the light. Like other recent Klarus lights, there are 2 UI modes on this light. Factory default mode is Outdoor Mode, which I found to work for EDC pretty well. 

 

You have a paddle switch that starts allowing the light to work on low either in momentary if just clicked briefly or if you click and hold for about 1 second it will stay on. Once in the on position this paddle can be used to step through the lights 4 main modes in increasing order. 8LM, 100LM, 400LM, 1600LM. 

 

Also on the tail cap is a larger round mechanical switch that will give you instant access to turbo. You can half press this for momentary or full press to lock on. Once the light is on you can use the paddle to cycle between modes. 

 

To switch modes when the light is off, press and hold the paddle for 5 seconds and the battery indicator on the front side of the light will begin flashing red/green. Then click the large primary switch without releasing the paddle. 

 

The second mode is a tactical setting where the primary button turns the light on to high, then use the paddle to change modes, and in tactical the light goes from high and decreases in brightness to medium (400 lumens), Low (100 Lumens), and then Moonlight (8 Lumens). To enter the strobe while the light is on, hold the paddle for 2 seconds. When the light is off, pressing the paddle will give you direct access to the strobe. 

 

Lockout in either mode can be accomplished via unscrewing the tail slightly to reset.

 

Recharging

The Klarus E1 again uses a proprietary battery here, where both the positive and negative terminals are on the traditionally positive end of the battery. The positive terminal has a plastic spacer around it that sticks out a bit. A normal flat top battery will work in the light with a magnet spacer but you will lose the recharging feature of the light. The light uses MicroUSB for recharging which is disappointing in mid 2020.

Speaking of recharging I charged the light from LVP at 2.86V to full at 4.18V in a total of 4 hours and 25 minutes. Charge speed was around and ranged from 0.66A to right at 1A. Definitely on the slower side but safe. What I didn’t like was the light’s LED indicator on the side changed from red (charging) to green (Charged) before the light was completely full. I got the full indicator an hour before the light actually stopped using current and I tested the battery here at 4V. It would be good to see the light actually go green when it was done charging instead of being almost done.

Pro

  • Good factory deep carry clip, but it only allows for tip up carry and it rotates a bit to easily.
  • Good fit and finish, it’s a good looking production light. 
  • 2 UI modes for users to pick from. 

 

Con

  • Minimal change from the Klarus E1
  • Proprietary battery, this time it’s larger capacity at least.
  • Doesn’t tail stand, or is magnetic, because of the dual button configuration on the tail cap.
  • Wasn’t a fan of taking it out of my pocket and having to change grip to turn it on.
  • Moonlight mode here is brighter at 8 lumens than the E1 which isn’t moonlight at all.

 

Conclusion

The Klarus E2 looks familiar because it is largely the E1 that’s slightly longer, with a different LED to produce more output (still in cool white only) and comes with the battery the larger capacity E1 should have shipped with originally. 

 

I like it’s size for an 18650 light, it’s short, and about as narrow as possible. It has a pretty good UI and I love that it has the optional Outdoors mode or Tactical mode. The light isn’t perfect though, I found in my daily IT work I missed the ability to tail stand and a magnetic tail cap, and I didn’t love having to rotate the light in my hand when pulling it out of my pocket to use it. Moonlight mode is too bright here at 8 lumens, and it steps down super fast from it’s highest output. It’s good to see they went with the larger capacity battery here vs the E1. I hope before the light ships they revise the firmware to let the green charged light come on at closer to 4.2v vs the 4.0v it comes on in my example. 

 

MSRP at a few retailers who are listing the light for sale now at the time of this video is about $70 which is a little on the steep side with the competition and a big step up from the E1. A drop in price would make the light more competitive. If you liked the E1 you will like the E2 as it’s basically the exact same light with a brighter LED and higher capacity battery that’s just slightly longer overall.

Olight i5T Cu Review (AA, 300 Lumens, Raw Copper, Great EDC)

Olight has another raw copper light out for all you copper fans with the Olight i5T Cu. This is a special edition of the i5T which has been released in several different editions in 2020. It’s a 2 mode light taking a AA battery with a deep cary pocket clip. It’s similar to the Olight i3T but larger. Thanks to SkyBen for sending this to me to review.

YouTube Version of this Review:

Follow me on Instagram: https://www.instagram.com/liquidretro/ 

 

Versions

There are a couple of versions of the i5T from Olight. There as a Shot Show edition they gave out to people, it was aluminum with a neutral white emitter, A CoVID relief special edition that was sold, it was aluminum and had some blue anodized accents on it, a normal black anodize and desert tan models, and the one I have here the in copper. Everything except the shot show edition has the standard cool white emitter. 

Packaging and Accessories

The i5Tcu came in what I would call a gift box. It’s a heavy duty white cardboard that’s finished nicely with a color photo on the front and a limited amount of details on the back. Inside the light was vacuum sealed in plastic with an anti oxidizer packet to prevent any patina from forming until it arrives in your hands. The only included accessory was the manual and GemTec AA battery that came preinstalled. 

Construction

No complaints here on construction quality, Olight does a nice job with these, and is one of my favorites when it comes to their raw copper machining. Everything is nicely chamfered, and polished. It also comes in the least oxidized state of any of the copper flashlights I have. The overall design here is a largely a scaled up version of the Olight i3T with a few differences. At the tail the buttons appear to be the same, as the i3T. The proud switch has a hard plastic edge and then a rubberized grip at the very top. It takes quite a bit of force to active the switch which I like. This one won’t come on in your pocket on accident. I do feel a bit of cell movement internally when pressing the switch which feels a little unnatural. 

The knurling on the tail cap is mostly horizontal with just a touch of vertical, mine seems to be not perfectly centered, like it is on the i3T. Not sure if this is intentional or just a slight manufacturing issue, either way it adds a nice amount of grip to unscrew the tail for battery replacement and style. Internally the tail section is made of copper too, and has nicely cut square threads that need a bit of grease.

The pocket clip is push on style but fits tightly, more on retention in a minute. The body itself has the double line spiral as the i3T does. It’s fairly deeply cut and the walls have minimal chamfer. It’s mostly for style but adds some grip to. The head is very plain, it has the model number and serial engraved into it and does not appear to come apart or it’s a one piece design. The lens appears to be plastic and be a one piece with the optic and reflector.

 

Size & Weight

I measured the length of the light at 95.5mm, diameter at 17.9mm and weight with an Amazon Basics High Capacity NiHM and clip at 112.3g. It’s a pretty heavy light, but that’s what you expect for copper

When I compare it to other similar lights I have, the diameter is a little smaller than my Reylight Pineapples or Ti LAN or the copper variants. Length wise it’s a little shorter too. If you liked the Olight i3T it’s just a little longer and slightly larger in diameter. It’s fairly comparable in size to the Olight M1T Raider, but smaller diameter and slightly longer. 

 

Retention

Retention on the i5T is good. I like to EDC 14500 lights, they are a good balance of size, weight, and most importantly diameter. This is especially true when I am wearing shorts. The i5T has a reasonably deep carry pocket clip, and on the copper model it’s a bronze PVD colored finish that fits pretty well especially after the light takes on some patina. It has a reasonable amount of room for material at the top too. It is using Olights dual direction clip which some love to hate. I will say my original clip on my i3T did snag not go back into shape. Olight did offer a replacement but it was only available in black, not the original PVD bronze copper it came with. It would be kind of nice if Olight included an extra clip with these special editions since they don’t seem to have spares.

 

LED & Beamshot

The i5T Cu here is running an Osram P9 LED in cool white. That said it’s not Olights typical 6500k, it’s warmer and more neutral, I would guess somewhere about 5500k or so. It does have a bit of a green tinge. The beam is using what Olight calls a PMMA lens. It creates a beam that is mostly a spot, with minimal flood. Good for EDC. There is a bit of PMW on low according to my oscilloscope and camera but I don’t notice it with my eye. If you are sensitive this may bother you.

 

Runtime & Heat

The i5T Cu is designed to run with 1.301.5V batteries so Alkaline and Ni-Mh batteries primarily. As you know from watching my other reviews I don’t run any light with Alkalines because they leak. Olight has provided the i5T with an Alkaline from the factory, so get it out and replace it with a high quality rechargeable Nickel metal hydride instead. 

For my testing I used an Amazon Basics High Drain cell, Previous testing shows these are slightly above 2500mAh, so basically on par with Eneloop Pro’s for half the cost. Peak output is right at 300 lumens and the light holds this for a timed 3 minutes before stepping down to right at 50% output where it runs for for just short of 2 hours and 30 minutes before stepping down and ran at it’s lowest mode. This time was the FL1 standard of 10% relative output. It eventually turned off completely at 5 hours and 45 min.  There is no Low Voltage protection built in to this light, so my battery had a voltage of 0.9V when I pulled it out. So when the light gets very dim, it’s time to switch the battery. Maximum heat I saw was 30.4C at the 3:30 mark.

I had read a few accounts of people running this light with Lithium Ion batteries so I wanted to test that too. Olight doesn’t recommend this and neither do I after testing. The light isn’t built for this at all, while it does substantially increase the output you will damage the light if you continue to do this due to the immense heat and increased voltage lowering the life of the LED. The light also doesn’t have low voltage protection so I used a protected KeepPower 800mAh cell to protect the battery from damage.

Total runtime with the Liion was 23 minutes to the FL1 standard, 31 minutes till protection kicked in. It’s a pretty linear decline until the 20 minute mark where voltage really starts having an impact on output. Temps are the big story here, this is the hottest light I tested when run this way and that makes sense given this is outside it’s designed mode of operation. Here a bit of a table of time and temps.

 

Time Temp in C Temp in F

0:09:00 69.3 156.74
0:15:00 72.7 162.86

As you can see the light gets dangerously hot, super fast. At 30 seconds it’s 36.1C at 3 minutes it’s 53.4C, at 9 minutes it’s 69.3 C, and at 15 minutes it’s 72.7C. To put this into a frame of reference most adults will have 3rd degree burns after 2 second exposure above 65C. So for this reason alone this light should not be run with Liion batteries it’s unsafe.

 

UI

UI here is super basic as it’s a 2 mode light. The light always comes on in it’s lowest 15 lumen mode and then if you press again you get the higher 300 lumen mode. There are no flashers or anything else. It would have been nice to see another mode to give you an ultra low 1 lumen mode. 


Pro’s 

  • Copper! With a great surface finish
  • Carries Well in the pocket
  • Good beam characteristics for EDC
  • Nice button

 

Con’s

  • Only Cool White is offered to the Public, there are probably better LED choices here too.
  • No moonlight mode
  • Pretty Middle of the road performance here. It would be nice to see 14500 support.

 

Conclusion

The Olight i5T Cu is a nice special edition light for general EDC, especially if you like the patina and characteristics that raw copper can develop over time. Olight’s timing is pretty good too with the positive antimicrobial characteristics of copper.That said you pay the price in weight here for copper, and I wish they would have went with a different LED and a more advanced driver. This is a basic light and it’s low mode is still too high for many who want a 1 lumen or less mode. Other then that it’s a nice high quality light I enjoy having around and I think you will too if you are a fan of raw copper.

Packaging & Accessories

Packaging is consistent with other recent Astrolux lights. A white box with minimal info on the outside other then the lights name and a silver line drawing of the light. Inside things are packed nicely with foam for protection. Accessories on this one include the light itself, A basic lanyard, and 2 adapter tubes for 21700 and 18650 batteries. No charging cable is included here which is disappointing considering this light requires USB-A to USB-C. 

 

Construction

My MF01 Mini is made from Aluminium and has clear anodizing. They offer a variety of colors including black, olive green, a tan/gold, and gray. They also offer a special edition in Brass, copper and an aluminum copper combo. Machining is average, a few tool marks can be found on flat surfaces, they are smooth to touch and nothing wrong for a light in this price category.

The light tail stands well with the flat base, and the lanyard hole is at the base. Inside it has large stiff dual springs, this allows it to accept 26650, 21700, and 18650 batteries with the included adapters. Rattling was a small problem with the 18650’s but not an issue with the larger cells. The body tube has a crosshatch knurling patterning put on.

The head grows in diameter some, it has 4 gills milled in on either side for cooling. The switch is domed and sits prowd. It’s a silicone button and has texture on top. It has LED’s underneath to indicate charge status like other Astrolux lights. Opposite the button is the USB-C charge port. It’s covered by a silicon port cover and includes an area for the tab to sit. It’s out of the way no issues. The bezel on my light is aluminium however a stainless steel one is available for extra durability. There is a glass lens on top of the 7 LED optic. Underneath the optic you have the daughter board with the secondary LED’s. The light is IPX7 water rated, and I had no issues running it under a stream of water. 

Size & Weight Comparison

This is primarily a 26650 light, but other similar sized batteries can be run. I measured length at 112mm, Minimum diameter on the body at 33mm, and maximum diameter on the head at 44mm. Weight with a 21700 battery installed was 254.6g.

The Fireflies E07 is a similar light also with 7 emitters and secondary LED. It’s smaller in diameter and lighter then the MF01 Mini, but the MF01 Mini does a better job of dissipating heat. That said the Mini can run 3 different battery types which is handy. 

 

LED | Beam | Runtime

The MF01 Mini is using 7X SST20 LED’s. My example is using the 4000k tint, but 5000k and 6500k are also available. With the 4000k tint, the CRI is 95, less so on the cooler tints. The SST20’s have a bit of a reputation for having a bit of a green tint, especially at lower powers and that’s pretty apparent here. Andril firmware is great but it also means the LED’s can be driven very low and this is where the green comes out. At higher powers the tint is pleasing to me, it’s no Nichia 219 but not bad either. The beam is floody, with ever so slight hot spot in the center. For a floody light it throws decently well. 

The light also has secondary LED’s in 3 colors, under the optic. Green on the outside, blue in the middle, and purple/pink in the center. These LED’s are on all the time the light has electrical contact.They are somewhat adjustable if you take the bezel and optic off there are 3 pots where you can adjust the brightness of each up to a point. There is a current limit so it’s better if 2 of the 3 are bright.

Runtime

I did my long duration runtime test with a Keeppower 5200mAh 26650 battery since that’s really what this light was originally designed for. It does fit 18650 batteries and 21700 with the included adapters. Total runtime here with this battery was just shy of 400 minutes. 99% of this time was at about 15% relative output.  Turbo output is good for under a minute on this light and it continues ramping down fairly quickly.

Heat on this light surprised me, I expected it to get quite hot based on other lights I have that are similar hot rods but that isn’t the case in my example and it’s a bit of a problem. So heat at 1 minute was 81F, at 5 minutes was 83F, and at 10 minutes 82F. The problem with this the light will start stepping down pretty quick. After I calibrate the light this should improve and allow the light to stay brighter for longer with the byproduct being heat. Low voltage protection kicked in at 3V. 

 

UI

This light is using Toykeeper’s Anduril UI. It’s currently one of my favorites available as it has a ton of options and neat little easter eggs that commercial UI’s don’t include. By default the light comes in ramping UI which is where I left it. The ramping is fast and logical. A stepped mode is available that you can configure as well if you prefer. 

The light has thermal controls, you can configure beacon mode, as well as 5 types of strobe including candle mode, party strobe, and lightning storm. You access these with 2 taps and a hold, and then two taps to change modes inside this group. Candle and lighting mode are my personal favorite. How practical these are could be a point where one could argue, but I like that they are present and it just makes things fun. Due to how you access these strobe modes I would not call the light a tactical UI or tactical light as you have to remember a series of presses and pauses to get there. 

 

Personally I find the UI to be easy to use for what you want to do most often, but a little more complex to get to those modes you don’t use very often. This is a UI where you should take a look at the manual or at least the graphical manual for the UI and spend some time playing with your light to get the most out of it.

 

Recharging

This light has an onboard USB-C port for recharging, however it doesn’t support USB-C to USB-C cables, meaning you have to use a USB-A to C cable for recharging. For me this kind of defeats the purpose of having USB-C. Charging was reasonably fast, I charged my 5200mAh Keeppower 26650 battery in 3 hours and 30 minutes at a max rate of 1.85A. The battery stopped charging at 4.19V.

 

Pro’s

  • 5 colors, 3 tint’s available in Aluminum, Copper, Brass options are also available
  • High CRI (95)  available with the 4000k tint option
  • Versatile battery options with this light (21700, 26650, 18650 all work and the light includes spacer tubes

 

Con’s

  • Only support for USB-A to USB-C Charging. Doesn’t work for C to C.
  • With great power and lumens comes heat! 
  • The SST20 LED’s in my example have a pretty green tint at lower outputs

 

Conclusion

Good competition for the Fireflies E07, Pretty good value at around the $60 mark normally or about $46 with my coupon in the description at the time of this video release. I enjoy secondaries on lights like this. They use minimal power and make them different from the competition. Overall a pretty good value light, hopefully Astrolux and other flashlight manufacturers will soon allow their USB-C lights to use C-C cables! Make sure if you decided to pick this one up, to take advantage of the color options here both in body color and tint. Let’s support one less black flashlight!
