Sofirn SC32 Review (Affordable EDC & Mini Tactical)

Welcome to my review of the Sofirn SC32, an affordable and powerful mini tactical EDC flashlight. This compact and durable flashlight is equipped with an SST40 LED, which provides a maximum output of up to 2000 lumens. It also features onboard USB-C charging, allowing you to easily charge the flashlight’s optional 18650 battery, giving you hours of use on a single charge. Whether you’re a professional, a hiker, or just someone looking for a reliable and versatile flashlight, the Sofirn SC32 is an excellent choice at a very affordable price. Thanks to Sofirn for sending it to me to review, and now let’s take a closer look at what this flashlight has to offer.

Packaging & Accessories

Sofirn has really stepped up the packaging here with the SC32. Instead of a generic brown cardboard box with only the company name on it, with the SC32 you get a white box with color photos and printing, as well as specs on the back. It features magnetic closure sides like you see on many Olight boxes for example, a real step up in quality, especially for the budget price these sell for. Inside the included accessories which consist of a lanyard, extra O-rings, USB-A to C Charging cable, and a manual are within another box to the side. An optional 3000mAh battery was included with my lights, and I recommend getting it as it’s only about a $2 difference in price.

Construction and Design

The light is made from aluminum and anodized in a more mat-black finish. One thing I immediately noticed was the difference in finish and Font between my two lights. The NW version I have is a more chalky finish and has the older Sofirn logo, the CW version is more of your traditional anodizing and has what I am guessing is their new logo in all capital letters.

The tail is glued to the body tube and features a flat recessed electronic switch with a big button pad in gray aluminum that’s grooved. I have zero issues with accidental activation here which is nice. The clip only attaches at the rear and is pretty tightly held on. The body tube has small fins milled in for good grip and a more premium look in my option than diamond knurling. Threads are raw, square cut, and well lubricated. This is a dual wall light to make that electronic switch work as well as onboard charging, and there is a spring on both ends of the light internally. One note is that there are exposed pogo pins (4x) on the rear of the PCB so this should be easy to flash the firmware on if you wish without disassembly needed.

The head of the light features the USB-C recharging hidden behind a silicone port that sits flush on what I will call the front of the head, with an LED indicator light to the side. The front of the bezel has short semi-aggressive crenulations protecting the plastic TIR lens.

Retention

Your retention options are simple on the SC32, The light comes with a generic lanyard that can attach on the clip. The pocket clip itself is the other option. It only attaches at the rear of the light, and is a dual-direction clip. It’s a fairly deep carry and has plenty of room to put onto the pocket of jeans. No major pain points here in my opinion.

SIze & Weight

The length of the flashlight is 100mm, with the diameter being 25mm. Weight with the battery and clip came in at 3.72oz or 105.7g. The light is IPX water rated and here are a few photos of similar lights that I might have.

LED & Beam

The SC32 is using the SST-40 LED, It’s available in both cool white and neutral white which I have samples of both here. Cool white came in at 5772k at 63.8 CRI on my Opple meter, and the DUV had no unexpected tints. The Neutral White version came in at 4638k and 62.9 CRI with very similar DUV. I do notice with my eyes a bit more tint shift on the neutral white version of the light.

The beam in both lights passes through a plastic lens. Sofirn calls this a Fresnel lens, and what it creates is a more floody beam than a TIR optic. While it has a hot center it’s not very defined and spreads out rather quickly. Better for shorter ranges than longer distances which we will see in my night shots.

Outputs

I tested the outputs on my Texas Ace Lumen tube and most outputs were a little under Sofirns claim. As expected Neutral white was a little less output than the cool white version. My only concern was Turbo outputs were lower than claimed by a decent amount. I think the battery may be part of this issue and I will update if I find something different.

Heat & Runtime

I ran various heat and runtime tests with the two lights I had. Both of the batteries I received tested slightly above the 3000mAh rating. The NW cell was 3115mAh, and the CW cell was 3043mAh. With the CW light, total runtime in Turbo and High were very close between 5:15:00 and 5:20:00. Turbo saw the large step down after a 1:15. The light does have active thermal management that’s set to reduce the 55C (122F) to prevent issues. I did test this on the NW light and the highest I saw on the exterior of the light was 47C. The only difference worth mentioning between the two lights was the runtime on NW was slightly less at 5 hours total.

UI here is very simple, long press from off to go to moonlight mode. Once on long press lets you cycle through the normal low, medium, high. Double-click when on to go to turbo and triple-click to go to strobe. The light does have memory mode.

Recharging

Recharging is accomplished via USB-C on the head of the light. The silicone port protector worked well, and stayed in place when not in use. There is a LED indicator near the port cover for voltage check and for charging indication.

LVP between my two samples averaged out to 3.0525V and charging time took 2.19:00 with max charging rate being about 1.6A. Charging stopped at 4.1V which is good.

Conclusion

Sofirn has stepped up their game with the SC32 in my opinion. The more premium packaging is nice and elevates the first appearance of the brand. They call this a mini tactical flashlight, but I would call it a great EDC option as well, due to it’s small size and easy UI. The one negative for EDC in a pants pocket might be the slightly aggressive bezel.

Sofirn continues to deliver great value here too, Before any sales you can order the light for $33 shipped with a battery at the time or ordering, and I am expecting to have a coupon for you to discount the price further.

I can fully recommend this light for the price here if you are in need of a new inexpensive EDC and want something that’s more on the floody side with decent power and runtime. It’s great to see LED tint options here. I would rather have tint options and low CRI like this light provides rather than an undesirable tint and high CRI.

Fenix TK20R V2.0 Review (3000 Lumens, SFT70 LED, 21700, USB-C)

Today I have one I am excited to bring you, it’s from a New brand on the Channel with Fenix and the TK20R V2. Through the years I have gotten a lot of questions on Fenix and what I thought of specific models and I and I just didn’t have the experience to answer, so I was excited when Fenix reached out to start working together. This is the first of 2 reviews for Fenix you will see in the coming weeks.

The TK20R V2 is an updated light that’s using a Luminis SFT70 LED, producing 3000 lumens, has onboard USB-C charging of the 21700 battery. You can check out more at https://www.fenixlighting.com/ The light I was sent is preproduction, and actually has a Luminus SST70 LED, however that has been changed in the production light to a Luminis SFT70 LED.

Here is a link to the USB-C Cable I used in the video https://amzn.to/3Dwt0rA

Packaging & Accessories

I received a preproduction light, and final packaging was not ready at this time. Accessories that came with mine included a USB-A to C charging cable, the light, and the branded button top protected 21700 battery (ARB-L21-5000). Mine came with a velcro patch as well, not sure if this is normal or not. Other things that are expected to come with the production model include a lanyard, holster, 2 spare orings, user manual and warranty card.

Construction & Design

I am only going to hit the high points here, and let the photos and video do the rest of the talking. The light is made from T6061 aluminum and nicely anodized black. At the tail cap you have 2 protruding buttons, a larger round mechanical switch that takes a good amount of force to push, and then a smaller rectangle mode button. The light does not tail stand as a result.

The pocket clip only mounts on the rear of the light. The body tube has concentric ring knurling like texture on the body, this provides a good amount of grip and looks nice I think.

The recharging port cover is worth noting here, instead of using silicone rubber covers like many manufactures do to seal the USB-C ports, Fenix’s solution on the TK20R V2 is to have a retained aluminum cover that twists one full revolution to reveal the port. It has orings at the top and bottom and lots of anodized threads, so it’s silky smooth. Also under this port cover is the battery level indicator and recharging status LED. This just makes sense to me and has nothing to catch, or get in the way like the silicone covers sometimes do.

Internally there is a stiff spring at the front of the light as well as in the tail, threads are smooth, square cut and a bit dry. Up front the head is glued in place but the bezel is removable. There is a crenulated bezel made of aluminum protecting the AR glass lens, deep smooth reflector and nicely centered LED.

Retention

Since this is a pre production prototype I don’t have the lanyard or holster that the light will ship with in it’s final form. What I can talk about is the pocket clip. It only attaches at the rear of the light and is relatively narrow for the lights size. It’s stiff and does a good job of retaining the light in my front pocket, with about 1” of the light sticking out.

Size & Weight

I measured the length at 152mm, maximum diameter at the head at 34.1mm, minimum diameter in the body at 26mm. I measured the weight here with the battery and clip at 203.2g or 7.17oz so a little on the heavy side. The light is IPX8 water rated and drop resistant to 1.5M.

LED & Beam

The Fenix TK20R V2 is using the Luminis SFT70 LED in cool white. The light I was sent is preproduction, and actually has a Luminus SST70 LED, however that has been changed in the production light to a Luminis SFT70 LED. My Opple meter shows it as 6035k and 67 CRI when on in turbo. In lower lumen modes it warms up slightly to around 5600k and has a notably green tinge to the beam to my eye. The beam has a pronounced hot spot in the center and minimal spill with some tint shift noted. Parasitic Drain was measured at a very low 1.8uA. There was very minimal PWM here, it’s basically constant current.

Below are the official outputs from Fenix. I will note the mode spacing is pretty good to the eye here.

Official Total Outputs for the SFT70 verison

Turbo – 3000 Lumens
High – 1000 Lumens
Medium – 350 Lumens
Low – 150 Lumens
Eco – 30 Lumens
Strobe – 3000 Lumens

Heat & Runtime

For all of my runtime tests I used the included 5000mAh battery and measured the % of relative output change, not total output (lumens). Starting with Turbo it lasts for about 2:20 before reaching equilibrium. During this time the light peaks at about 45C. It runs at this equilibrium very steadily out to the 3 hour mark.

I ran the same test and compared turbo to high and to medium modes for total runtime. You can see in the graph that High in green had a few more stepdowns but ended up at a very similar total runtime as turbo. Medium is a very flat output curve out to 7:40:00 mark where it begins stepping down several times, eventually shutting off at 9:18:00 when LVP on the battery kicks in at 2.89v.

UI here is very simple. The light has 2 buttons on the rear tailcap of the light. There is the larger power button which Fenix is calling the Tactical switch, it’s a forward clicky switch with momentary, and then the smaller button which they are calling the function switch. You can half press the tactical switch to turn the light on in the last mode used before locking fully on. Once on you use the function switch to cycle through the 5 modes in a linear manner. The light does have memory mode. At anytime you can press and hold the function switch to get to strobe mode.

Recharging

I already talked about how the recharging port works on the TK20R V2, it’s under the aluminum nut that unscrews from the base of the head. It’s nice robust design. Also inside that port is your LED battery status indicator and charge indicator. When recharging it starts as red, and goes green when charged. The light is not capable of being used when charged. It does support C to C charging but has no PD charging support.

The light is powered by a Fenix branded button top, protected 21700 battery (ARB-L21-5000) with a capacity of 5000mAh. I tested the capacity with my Vapcell S4 Plus charger and came away with 4863mAh. I tried the light with an unprotected button top battery and had no issues.

Charging itself using the onboard USB-C port and included battery from LVP at 2.89v to full at 4.226v took 2:38:00. The light has a soft start charging when the battery is low before it jumps up to about 3A at the very beginning, and it falls as the battery charges. So a bit of a different curve then what I typically see.

Final Thoughts

I am excited to see Fenix on the channel. It’s a brand that I can find locally at two different sporting goods stores, and a LGS, which I think can be appealing to many people if you need something of quality and don’t have the time to wait for an online order. Of course they can be found online as well.

As for the Fenix TK20R V2, It’s a pretty nice semi tactical light. The controls are easy to use, and strobe is easy to access if you want it. It has a useful beam that’s a good combination of flood and throw without making too many compromises. That said it is still cool white, and at lower tints the LED does have a pretty strong green tinge neither are my personal preference but at the higher end of the consumer market where this light is aimed won’t care like enthusiasts do. The USB Port cover design here is really nice, and I am surprised more lights don’t do something like this.

Nitecore P20iX Review (4000 Lumens, 4 LED, 21700, USB-C)

Today I have a new Quad LED light from Nitecore with the P20iX that produces up to 4000 lumens on a 21700 battery and it features onboard USB-C charging with Tactical and Daily modes. Thanks to Nitecore Store for sending this to me to look at and review.

Pickup the Nitecore P20iX from NItecoreStore at https://bit.ly/2YTVTKT

Packaging & Accessories

Packaging is a step up, with a nice high quality box full of information. Inside the light is packed in foam with all the accessories underneath. It reminds me a bit of how Olight does theirs. Accessories include a branded lanyard, Extra Oring, USB-A to C Charging cable, Pocket clip, CR123A battery adapter, hard plastic belt holster and a Nitecore specific 5000mAh 21700 battery.

Construction

Machining on the aluminum light is good here, and the anodizing is high quality. The tail cap has a large off center mechanical on/off button that’s covered with a textured silicone boot. It stands proud making the light unable to tail stand. Your mode switch is a flat, textured area. This is flush, but protected by the outer rim of the tail cap. For me this was harder to find in the dark and hard to actuate with gloves on.

The body has some tame knurling on it, the pocket clip attaches near basically the middle of the light in either direction. The head does not separate from the body. On the head you have a large antiroll ring to keep the light in place on it’s side. You do have a blue LED that’s built into the side of the light that’s used as a charging indicator, similar to the MH11 I reviewed earlier this year. The charging port has a large silicone cover and it fits tightly.

At the front the light has a short bezel that doesn’t stand out from the lens very far, it has 3 protruding areas each with a small ceramic balls in them, I presume for striking glass that law enforcement may use. I believe the bezel is a little different material due to it’s slightly different finish. The lens is glass, and underneath there is a custom quad silver reflective optic for the 4 leds.

Size & Weight

I measured the length of the light at 140mm. Minimum width on the body at 25.4mm, maximum diameter on the head at 32mm. Weight with the included battery in the light and no other accessories is 191.7g. The light is IPX68 water rated and drop rated to 2M.

Retention

The P20iX has a couple of retention options that come in the package. First is the lanyard which is primarily slip fit over the light or attached to the clip. The clip which is a press fit is fit down pretty low, which leaves a lot of the tail or the head of the light sticking up out of the pocket. This is disappointing to me personally. That said the plastic belt holster that the light comes with does a pretty good job if you want to carry the light on your belt or on a mole vest. The light clips in with the front bezel facing down.

LED & Beam

THe light has 4 Cree XP-L2 V6 Led’s in cool white with a maximum output of 4000 lumens. The tint here is cool white, likely around 6000k or a bit higher. The beam is somewhat compromised in this quad. The hot spot is pretty round but it’s not a smooth transition in the spill and you do get some Cree Rainbow. The very outer edges are a bit rough. That said it’s hard to nice in real world use at distance.

Heat and Runtime

For my Heat and runtime I ran the light with the included 21700 battery. The light will run on 2x CR123 batteries in the included adapter if you wish but you generally get less output and for a shorter time. With the 21700 on turbo the light lasted only 30 second before step down. This was disappointing especially since the heat during this time at least measured externally didn’t amount to much. Step Down was pretty significant as you can see from the graph. As the light continued to run heat pretty quickly increased though up to about 55C, at about 21 minutes. Thermals eventually regulated at about 25C for the duration of the runtime. The light went into it’s lowest mode after about 3 hours of runtime where it continued for another 2hr and 20 minutes for a total runtime of 5:20:00.

I did another runtime graph with comparing runtimes of the 4 highest output modes, Turbo, Highest, High and Medium. The 3 highest don’t have a ton of overall impact on output. Medium ran for considerably longer, a solid 8 hours without stepdown.

The P20iX has 2 modes, a Daily mode which it ships in with 5 individual modes, and then a Tactical mode with 4 individual modes. To switch between them, you turn the light on, press and hold the mode button on the tail and unscrew the light. It will flash Once for Daily, or twice for tactical and then you screw the light back together for it to be remembered.

Daily mode is where I am using the light most. In this mode the light starts in the lowest output and goes up with each press of the mode button. It has memory so you can shut the light off and when it comes back on it will be in the previously used mode. This mode has outputs of 2,50,300,850,1700 lumens, and then to get turbo (4000 lumens) you hold the mode button in and it works in a momentary manner. Double click this mode button to go to strobe in momentary.

Tactical mode is similar but it goes from highest output including turbo down, and only has the 4 brightest modes.

Recharging

The light features a USB-C port on the side covered by a tightly fitting silicone rubber cover. I used the included 5000mAh 21700 battery to run my charging tests and found total charge time took 3hr and 54 min. Max charge rate I saw was 2A. The light will charge via USB-C PD without issue. While charging the battery in the light, it’s not possible to use the light at the same time. The LED on the side will blink when charging and go solid when charged. When a battery is inserted it will also blink the voltage.

The included battery looks to be custom with a negative terminal on the positive end. It’s a long protected battery with a shallow button top. It fits in my Vapcell S4 Plus charger and works just fine there. Due to that length I wasn’t able to find another battery I had that fit this light

Conclusion

This is a pretty nice high power flashlight from Nitecore. I like that it has a pretty practical daily mode, and that it’s not all tactical. It’s an interesting choice to have Turbo be only in momentary in daily too. I do wish Turbo had more runtime before step down though.

The clip on belt attachment here works well, and I suspect that or in a bag is how most would carry this light. For me the pocket clip is super impractical due to it being so far down the light, and that’s a disappointment.

I wish the battery was more universal, but this semi proprietary format with the protected batteries and positive and negative terminals on on side of the light seems to be the way most manufactures are going with their 21700 light that have onboard charging. It’s a disappointing industry trend in many enthusiasts minds. To be clear this is an industry thing, not just Nitecore.

Overall this is a solid light for general purpose and has some nice tactical features without being 100% tactical. I can see this being a good option for many if you don’t mind the cool white LED’s or short turbo runtime.

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.

Join the Facebook Page: https://www.facebook.com/LiquidretroReviews/

Enjoy this review? Buy me a Coffee: https://www.buymeacoffee.com/Liquidretro

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.

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.

Packaging & Accessories

The TT20 is using Thrunites standard heavy but minimal cardboard box. It’s lacking information like normal but that’s fine since it’s designed for online direct to consumer sales. Inside you get the flashlight itself, along with the proprietary 5000mAh 21700 battery, a basic holster, and a USB-A to C cable. The extras bag includes 2 Orings, a spare rubber tail boot, extra orings, 2 spare USB Charging port covers, and a branded lanyard.

Construction

The Thrunite TT20 is available in 2 colors currently, a standard black and a Red “Outsider” edition that I have here. It’s a really nice rich vibrant red, I always like seeing lights in different colors. This version replaces the TT20 model number engraving with the Outsider’s logo. (Youtuber).

Thrunite added a large mechanical tail switch on this light making it “tactical” It’s cover is grippy and you can connect the lanyard at either side of the tail switch. It has some straight knurling for trip to help remove the tail cap. Inside the center contact is slightly spring loaded.

Threads are anodized and square cut. The battery compartment has very tight tolerances with the battery, when inserting the battery it’s cushioned by a layer of air escaping, normally you don’t see these types of tolerances in production lights. It doesn’t suffer the problem of the USB port cover popping off either which you sometimes see when inserting batteries in lights. The surface of the light has a fairly tame grip level for a tactical light, it’s a similar milled pattern to what the TC15 and T2 have. The 2 way clip is reversible on either end of the light, I have switched mine from where it came preinstalled.

The head of the light is pretty plain, and glued to the body of the light at the front. You have an anti roll ring at the front. The e-switchis similar in shape and design to other Thrunites but this time black anodized and seems to stick out slightly more.It’s still got the LED indicator underneath for battery power levels. The battery charging port is opposite, and it has a fairly large silicon cover. The little pull tab can get in the way causing the flap to open unintentionally. The front of the light has a scalloped bezel that’s non tactical but allows light to escape when standing on the head. The lens is anti reflective coated, and underneath is a deep smooth reflector and the LED is nicely centered. The light is IPX8 water rated and had no issues with time in a bucket of water.

Size & Weight

I measured the length at 136mm, max diameter at 29mm, minimum diameter at 26.5mm. Weight with the battery and clip installed is 181.1g. For me I find it fits in the hand pretty well and it’s a decent size for a 21700. Not the smallest light in it’s class but not the largest either.

Comparison

The Olight M2R Pro is the most obvious light I have as a competitor. It also is a 21700 battery, tactical tail switch with front button, and a similar overall size. Weight wise it’s within 1 gram. I think the Olight is a bit more tactical, with the more aggressive bezel, more aggressive body section grip, it’s more focused beam, and the 2 stage tail switch. Clip wise I have to give the advantage to Olight but the TT20 is good too. See the pictures below for how it compares to the Thrunite T2 and TC15.

Retention

The TT20 comes with a lanyard that you can attach onto the tail cap if you wish. This is approaching the size of light where I start to use lanyards, but for now I will leave it off. It also comes with a holster, it does the job but is fairly basic, with just a D-ring and belt loop. This is one area where the Olight M2R Pro’s holster is clearly better.

The pocket clip on the TT20 is dual direction and pretty good. It allows for a fairly deep carry in the pocket with only about 10mm of the light sticking out of the pocket. The clip is mountable on the front of the body tube or the rear. I suspect most people will rear mount it like I have it here. It’s a non captured clip so it does rotate around the body of the light. The TT20 will fit on a hat if you want it to but with the 21700 battery it’s heavier then I normally want to do with a strap on clip.

LED & Beamshots

The TT20 is using the Luminus SST70 LED in cool white. This is my first light with this LED as it’s fairly new and new to the flashlight market as well. It’s an XM Size LED, Quad die LED so it would be a replacement for a Cree XHP50, but it’s physically smaller, more like and XHP35. With it installed here in the TT20 there is a small donut in the beam at distances less then 3”. At low powers, I get a bit of green/yellow in the beam, but these go away at moderate power levels and the beam is a cool but not cold tint. There is a moderate hot center and the spill is moderate. There is a small ring at the outer edges of the spill.

This gets a bit into the UI of the light but during ramping it’s not a smooth ramp. It seems as if there are a ton of small fixed steps as it’s increasing or decreasing in brightness instead of a nice and smooth ramp like you have on most lights with ramping. Once you stop it’s even and I don’t notice any PWM to my eyes or camera. My scope says there is a tiny bit, so no concerns.

Working voltage is 2.7V-4.2V which means you are only using the “proprietary” 21700 that the light comes with. FIrefly is measured at 0.5 lumens, infinity low starts at 31 lumens up to 1468. Strobe is 1294 lumens and Turbo is 2526.

Heat & Runtime

I did my runtime tests with the included battery at room temps of around 73F, non cooled. Turbo on the light lasts for 1:15 before it starts stepping down and it’s stable again at the 3 minute mark at around 23% relative output. I saw peak temps at 1:30 of 52C. The light was able to hold this 23% relative output for a long time, 3:30:00, total runtime was 3:36:00. LVP was measured at 2.849V. The standout for me is if you just skip turbo and run the light in infinite high, it’s around 1300 lumens and the light is able to hold this for a little over an hour (75 min).

When I compare the runtimes to the Olight M2R Pro, the Olight is able to withstand it’s turbo output slightly longer at about 5 minutes (while stepping down), and it’s bulk of the runtime was closer to 38% but for a shorter 2:33:00 and a total runtime of 3:15:00.

The UI on the TT20 is different for a tactical light. It’s ramping with the use of the front button. It starts on low and if you long press from off the light comes on in firefly mode. Once on in normal mode you can press and hold and the light will begin it’s ramp up, as mentioned the ramp isn’t very smooth or fast. A full ramp from low to high takes 5.44 seconds which is a long time in my opinion. The light flashes at both ends 3 times and you can ramp in a loop low to high then ramping back down to low. It’s harder to start the light out in low especially if coming from moonlight mode. Double click on the front switch to jump to Turbo or use the tail switch to go to turbo at any time. Triple click the front button to get into strobe. There is memory as well for modes other than Turbo. When using turbo from the tail switch you can’t adjust the mode.

The light does have electronic lockout mode, if you are a subscriber here you know I rarely if ever use lockout through the UI. Thankfully mechanical lockout is an option by just breaking contact with the tail. This will prevent the tail from working but the E-Switch will still work thanks to that proprietary battery. The light basically has 2 physical paths for current to flow. I find myself sometimes turning on electronic lockout accidentally here if I press to long to get to firefly mode.

Charging

The TT20 has a onboard USB-C port for charging. It’s only compatible with USB-A to C, and not full C-C or USB-C PD unfortunately. Total charge time was 3:03 which is pretty good. Max charge speed I saw was 2.1A. The curve here is different from I typically see but it did decline as the battery charged. The battery measured as full at 4.199V.

The battery will charge in some external chargers too if you have a large or pointy contact to make it over the plastic spacer on the battery. Alternatively if you have a charger that accepts long cells like the VapCell S4 Plus I recently reviewed, then a 1mm rare earth magnet will work as a spacer if needed. With the S4 I don’t need a spacer it turns out.

As mentioned before the 5000mAh 21700 battery here is proprietary since it has both the positive and negative contact on the traditional positive end of the light, and it has small plastic spacer here. The battery is interchangeable with the Thrunite T2 and Olight 21700’s like what’s on the M2R Pro. The Olight battery will run in the Thrunite TT20, but not the other way around. This is done to reduce the lights diameter, so it can run without an inner tube, so the E switch and tail switch can both operate.

Pro’s

Body Color options, but I wish these were not cobranded.
Better value and longer overall runtime then the main competition.
It can sustain a high percentage of infinite high for quite a while.
New SST70 LED that I think we will be seeing a lot more from manufactures, hopefully in Neutral white soon.

Con’s

The red anodizing is a great color but doesn’t seem to be as durable as black.
Ramping isn’t steady and suffers noticeable PWM during the ramp. It’s also slow.
The UI here isn’t my favorite, it’s a clumsy mix of what I will call Everyday tactical.

Conclusion

My conclusion I come away with this light is, is it really tactical? The inclusion of the ramping suggests to me it’s more for general everyday use, with the tail cap being the more tactical feature since it allows you to go to full turbo instantly, but when using the tail option you can’t adjust the mode and it’s only turbo. I like how with the Olight M2R Pro, the tail switch is 2 mode, so it’s easy to get to but you have the option of if you want full power or not.

To me the TT20 more everyday tactical than full on tactical. The beam to me is more everyday than tactical too with it being less focused and more flood then the M2R Pro. That said the TT20 is a nice value compared to many othe the other 21700 lights in the price category. It’s nicely made and carries better than I expected in the pocket. The runtime on infinite high is great too, It’s easily able to sustain over 1000 lumens for over an hour. In my opinion I can recommend the TT20 for general use if you’re OK with the UI and slow ramps but I probably wouldn’t recommend it for a true tactical operator type situation.

Astrolux MF01 Mini (5500 Lumens, 7x SST20 LED, USB-C Recharging (Kind of))

Astrolux has gotten into the multiple LED flood and secondary LED’s with the MF01 Mini I have before me here. It’s available in 5 body colors, 3 material choices, and 3 LED tints with a high CRI option I have here. Thanks to Banggood for sending this to me and providing my viewers a discount. Make sure you check the description below if you are interested in this 5500 lumen light.

YouTube Version of this Review:

Get the Astrolux MF01 Mini at Banggood for $45.99 with Coupon code BGMF01Mini at http://bit.ly/340Nczj

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.

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!
