Sofirn SC21 Pro Review ($20 Shipped, 1100 Lumens, LH351D, USB-C)

Sofirn has a revision on their SC21, and they are calling it the SC21 Pro. The main difference is that it’s running Anduril 1 despite what the manual says. It still has the Samsung LH351D emitter as the non pro version, onboard charging, and retrains the 16340 battery. Thanks to Sofirn for sending this to me to review.

Packaging & Accessories

Packaging is Sofirns standard no-frills box. Inside the accessories include the light itself, a USB-A to C charging cable, pocket clip, lanyard, and Orings. The 800ma 16340 battery is optional but it only increases the price by about $2. Well worth getting in my opinion. The manual has a rather large misprint, saying that this light is running Anduril 2, when in fact it’s running Anduril 1. This makes the diagram and operating instructions different.

 

Construction & Design

The light is made from aluminum, and available in 3 colors, black, red, and the green I have here. The tail cap is magnetic and allows the light to tail stand even with a lanyard. The pocket clip mounts near the tail only and is non-captured. Knurling is a pretty standard diamond knurling of average grip. Threads are anodized, greased, and smooth. Internally there is a tail spring, upfront just a post in the head. There is easy access to the pogo pins to allow you to flash other firmware or different firmware versions if you want to. 

The head itself has the model name and brand engraved on the front and the “required” markings on the back near the charging port. I think the warning hot at the head is unnecessary even though yes it gets hot. The charging port cover is opposite the switch. Sofirn has used this port on other lights. In this case, I find it a little hard to get out of the way and for some reason a little tricky with the cables I had to keep charging. The port does seem to be set back a bit deep. At the top, there is a minimal smooth bezel, with the AR glass lens, and a light orange peel reflector underneath. 

 

UI

Despite what the manual says this light is running Anduril 1. Sofirn tells me that there was a misprint in production and that the manual is created well in advance. Future versions may ship with corrected manuals. I don’t see Sofirn has posted a corrected manual on their website yet, which would be nice to see them do. I won’t go into depth here with Anduril because most of us know it by now. You have the option of a ramping mode and stepped mode, and all the goodies that Anduril offers. It is disappointing though that a light that came out in mid 2022 as a new design and a “Pro” model doesn’t ship with Anduril 2.

 

Size & Weight

For a 16340 light this isn’t the smallest in class, and is a bit on the longer side of things, more in line with my 18350’s almost instead of 16340. I measured the length at 73mm Max diameter at 22.5mm and weigh with the clip and battery at 2.11oz or 60g. It’s IPX8 water rated too. 

 

Retention

I enjoyed carrying this light around on some recent trips out of town. It’s nearly the same size in diameter as my Reylight Lan/Pineapples which I enjoy carrying typically. The light has a dual direction pocket clip that attaches at the back and rotates but is pretty tight. It was a little difficult to get it started when putting it in the pocket due to the tension, but this tension also creates security which is a good thing. It’s a decent pocket clip that’s very deep carry which I like. There is also a place at the tail to attach the included lanyard. 

 

LED & Beam

The light is using a Samsung LH351D in neutral white, and high CRI. I measured 4951k and 96CRI with my Opel meter. My sample didn’t have any green tinge you sometimes see with the LH351D. The beam has a large hotspot, minimal spill, decent for EDC, but they could have used a TIR here and saved some length most likely. There is PWM here, as you would expect with Anduril, but it’s not an issue. The button on the light does have a built-in green LED that can be configured in the UI for low, high, blinking, and off. In low it’s not a huge consumer of power. 

Due to the nature of Anduril, I won’t give specific output measurements since the light doesn’t have defined modes. I will say when I first started the light I saw 1044 lumens, and at 30 seconds I saw 028 Lumens.

 

Runtimes & Heat

I used the optional Sofirn 800mAh 16340 battery for my calibrated runtime tests. Turbo lasted here for about 4 minutes before stepping down significantly to about 250 lumens to cool off. As it cooled it did increase output. The total useable light was 35 minutes, but the light kept running in the absolute lowest mode to 1 hour. Max heat I saw during this time was 63.5C at about 5 minutes. Keep in mind this was after I calibrated the light and raised that temp threshold.

 

Recharging

The light has built-in recharging via USB-C. I had no issues using USB-C to C or PD Chargers here. The port cover is good as mentioned but kind of large for this small light in my opinion. I tested with the optional 800mAh Sofirn battery. I tested it at 734mAh of capacity. The light charged from where it shut off to full in right at 1:06:00. Max charging rate was 0.9A which is slightly over 1C for the included battery. The shape of the charge curve here was pretty normal. 

 

Final Thoughts

There really isn’t much here that’s different on the SC21 Pro vs the non-pro. A 100-lumen difference isn’t going to be very noticeable to the eye. The biggest difference is the firmware where the SC21 Pro is running Anduril 1 which enthusiasts are going to like, and muggles are going to find confusing. 

They kept the exterior design which I think is solid, and the pocket clip here is pretty good. Best of all the LH351D returns in a neutral white and high CRI. Add into that it’s very affordable at $26 with the included battery before any additional discounts. It’s magnetic and available in 3 exterior colors, overall a pretty great value. Sofirn continues to bring in great budget options to the marketplace. In this physical size of light, you can certainly pay more for a light that I don’t think has as nice of an emitter or as good of UI. This would make a nice gift or entry into the EDC and flashlight worlds without breaking the bank.

Thrunite BSS W1 Review (693 Lumens, SST20, 16340 Battery, Onboard charging)

Thrunite has a new light in their BSS (Black Scout Survival) series of lights this time focused on the compact small EDC market. This light produces 693 lumens from an SST20 LED and a 16340 battery. It has a deep carry pocket clip, and is available in two different colored bodies. It’s very similar to the Wowtac W1 I looked at earlier in the year with a few differences. Thanks to Thrunite for sending this too me to look at, if I have a discount for it make sure to check the description below.

Packaging & Accessories

Packaging here is a rather small cardboard box that folds up from the top. On the side it lists the option the light is in, interestingly a black version and NW is optional here but those options are not listed for sale currently. Inside you get the light itself, along with a 16340 battery. Mine here happens to say it’s a Wowtac (Sister company) so maybe they had some wrappers leftover? Other accessories include the pocket clip, microUSB to USB cable for charging, manual and a bag of 2 spare orings, 2 spare USB covers. 

 

Construction

The W1 is made from aluminum and at current time is available in an OD Green and a Blue. I like the green color here myself quite a bit. The back end is mostly flat, it has a small milled center thats slightly lower with the Black Scout Survival logo engraved in the center. On mine the logo doesn’t really seem to be lined up at all with the head. The tail is magnetic and pretty strong, it has no trouble holding the weight of the light up. 

The pocket clip attaches at the rear of the light only, it’s a non captured clip and the tail and body are a one piece design. The groves milled into the body section are nice, they give quite a bit of grip but should clean up much better than traditional diamond knurling. The body also tapers in, to give the light the feeling of thinness

The head section of the light is a decent amount larger than the body, especially around the button and USB port area. This does change how the clip fits the light, more on that in a minute. This larger section serves as kind of an anti roll ring. The button is slightly recessed and protected with the aluminum around it. There is a LED underneath to give a charging status. Opposite the button is the charging port. It’s covered with a silicone cover. Not the best design I have seen but effective for the price. The front has a very shallow bezel that’s smooth. It looks to be a 2 piece design but I can’t get it to budge. The lens is anti reflective coated and the reflector does have an orange peel. The LED centering isn’t perfect but this doesn’t seem to have a noticeable effect on the beam.

 

Size & Weight

I measured the length here at 67mm, maximum diameter at 23.22mm at the head, and minimum diameter at the body at 18mm. Weight with the battery and clip was 51.5g. The light is IPX8 water rated.

 

The Competition

The closest light I have to the Thrunite BSS W1 is the Wowtac W1. As you may or may not know Thrunite and Wowtac are sister companies, and these two lights are very similar in terms of physical appearance, design, and shared parts. There are some differences, most obvious is the body tube differences. The Thrunite BSS W1, has in my opinion a more attractive body tube, with its linear milling, it’s also a little slimmer by 2mm. The heads are the exact same design with the only difference being color, and accents. They have the same button, USB Cover, bezel, lens, and reflector. The heads are also interchangeable between lights. 

 

The Olight S1R Baton II and S1 Baton Mini are both smaller then the Thrunite BSS W1, in terms of length, and as far as the mini has very similar maximum performance. One big difference is that the Olights carry bezel up, and the Thrunite is bezel down carry.  

 

Retention

The Thrunite BSS W1 uses a non captured dual direction clip that only fits on the tail of the light. It’s a pretty tight clip, enough so that it does scratch the anodizing, it’s very deep carry which is great and has enough space to fit over the pocket of my jeans to clip onto the pocket. The light also has a small place in the tail to allow a small diameter lanyard to be attached if you wish.

 

LED & Runtime

The Thrunite BSS W1 uses a SST20 LED in Cool White. No tint data is given directly. When I compare the beam to the Wowtac W1 it’s very similar, the SST20 in the Thrunite is slightly more neutral in tint to the Cree G2 in the Wowtac. The beam hot spot is slightly large as well. On this style of light I personally prefer a TIR style optic, because I think it provides a better overall beam for EDC use, that said the traditional reflector design here does throw further. 

 

Thrunite lists the output specs of the BSS W1 as the following.

  • Firefly 0.5 Lumens
  • Low  7.5 Lumens
  • Medium 58 Lumens
  • High 215 Lumens 
  • Turbo 693 Lumens with step down to 215 lumens after 1 min.

 

Heat & Runtime

Turbo runtime on the BSS W1 was 1:15 before step down, relatively short but this is a small light. Past here it seems to follow the curve of a non regulated driver. It ran at 30% relative output for right at an hour before slowly stepping down. Total runtime was 1:43:00 before the light shut off with the battery measuring 2.925v.

 

UI

UI here is extremely simple. From off, long press to enter firefly mode at 0.5 lumens. Once on long press to cycle through the 3 normal modes. Double press to go to turbo, or triple press to go to strobe. There is memory mode here. No lockout mode is here but you can mechanically lock the light out if you wish by a ¼ twist. 

 


Recharging

Recharging is accomplished via MicroUSB onboard the light. The charging port has a small silicone gasket that’s hinged at the top at one point. It’s not the best design I have seen, not the worst either. Charge time took 1:21:00 in my testing, with the max charge rate being .46A which is safe for this small of battery. The fully charged battery measured 4.145V. 

 

Pro’s 

  • Very inexpensive (Less than $30)
  • Only a cool white emitter available at this time.
  • Blue and Green anodizing are available.

 

Con’s

  • Not a crazy amount of performance but it is small.
  • MicroUSB instead of USB-C
  • Bit of a green tint on lower power modes.

 

Conclusion

If you are new to EDCing a flashlight, and wanted to try something small out, this would be a great option to try without breaking the bank. If you just wanted a small flashlight to use on a hat, carry in a bag or purse, or just wanted an impulse buy in a color you liked this fits all those applications here too. 

 

For EDC this is a decent light. The clip design allows for a pretty deep carry which I like, but the head design means I need to pull it out slightly to slip the clip over the side of my pocket. I like that it’s available right away in colors, and that they didn’t wait for a special edition with colors later on. It’s a little disappointing to see that it didn’t go to USB-C for the onboard recharging. 

 

The Thrunite BSS W1 is very similar to the Wowtac W1 that I reviewed last year. The exterior designs are slightly different, and I prefer the Thrunite BSS W1 here. I like the two anodizing colors being offered here an OD green and a nice blue. The SST20 LED is a little brighter than the Cree emitter used in the Wowtac W1. For the minor price difference (Around $25 total price) here between the two models and the availability of body colors, I would say to  buy the Thrunite BSS W1 over the Wowtac W1 at this time but I can’t say you would be wrong choosing either.
