Product Information

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor. Also, here’s the light with the worst PWM I could find. I’m adding multiple timescales, so it’ll be easier to compare to the test light. Unfortunately, the PWM on this light is so bad that it doesn’t even work with my normal scale, which is 50 microseconds (50us). 10ms. 5ms. 2ms. 1ms. 0.5ms. 0.2ms.In a display faster than 0.2ms or so, the on/off cycle is more than one screen, so it’d just (very incorrectly) look like a flat line. I wrote more about this Ultrafire WF-602C flashlight and explained a little about PWM too. User Interface and Operation Releasing while ramping and then holding again within 1.5 seconds will change the direction of ramp. When ramp reaches the highest level, the light will blink once to indicate. It does not blink when reaching the lowest level. LED and Beam What does that mean though? It means that the light thinks my room temperature is 14°C or 41°C. That’s far (or very far) off – my room temperature is around 22°C. It also means that there’s only a tiny window of operation before the light hits the thermal ceiling as programmed (probably 50°C but I’m not sure). During use, the indicator near the charging port (which you can see below) gives a brief indication of the approximate cell voltage. Charging

In my review copy of the Sofirn SC31T tactical flashlight is a Luminus SST-40 emitter, in 6500K. This emitter is surrounded by a smooth and quite deep reflector. Notably, there are two versions – the ATR version, and the older version which doesn’t have thermal regulation.Long Battery Life: With its efficient power management system, the SC32 HCRI flashlight offers impressive battery life, providing you with nearly 2.5 hours of continuous use on High mode. Say goodbye to frequent battery changes and enjoy extended runtime for your outdoor adventures or everyday tasks. Part of how they did this is by making lights we want to buy, selling them for cheap, and catering to the customer while improving and launching new products. So far it’s worked, since if you identify as a flashlight enthusiast, you probably have a Sofirn light. Tail E-Switch for Easy Operation: The SC33 is equipped with a convenient tail e-switch, making it effortless to operate with just one hand. Experience seamless mode switching and effortless brightness adjustment with this user-friendly design. With 6 brightness levels and 3 special modes (strobe, SOS, beacon), the SC33 offers versatility to adapt to various situations. Whether you need a focused beam or a signaling function, the SC33 has got you covered. Enjoy intuitive control and a hassle-free lighting experience with the Sofirn SC33.

Okay, we all know Sofirn is an OEM factory making lights under their own brand, and making them for other companies (Wurkkos, and masquerading for Astrolux occasionally). Either way, they’re a popular brand. My first unmodified flashlight was a Sofirn SP10S I bought in early 2020, and this is a good illustration of how Sofirn has become firmly entrenched in the flashlight enthusiast’s repertoire. Surprisingly, the bezel is not glued down. Not only that but the threads are lubed. Usually manufacturers don’t want you getting into the bezel, but on the SC32 it’s wide open, meaning emitter swaps will be a breeze. These beamshots are always with the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure. The cell goes into the light in the “usual way” (which is to say that the positive terminal of the cell goestoward the head).Turbo lasts just under a minute while high takes almost three and a half minutes to step down, but they both converge at the medium level, and all three modes stay there for almost 5 hours. Really, aside from the short burst at the beginning, this is a ~300 lumen light. It would’ve been nice to see it sustain high for a bit longer than that. Sofirn has made quite a name for themselves, churning out affordable, highly functional flashlights for the masses, and they keep getting better. Sofirn keeps their finger on the pulse of the marketplace and knows what’s hot and what’s not, so if something isn’t stirring the Kool-Aid, they fix it. The SC31T is a perfect example of this. Tactical-style flashlights are hot items, and every big-name manufacturer makes one (or more). I’ve been able to test some of the best on the market, and have a good idea of what makes a tactical light, well, tactical. Unfortunately, it is important to note that the Sofirn SC32 underperforms by about 25% all around. In reality, the visual difference between 1500 and 2000 lumens is hard to discern, but what’s advertised and how it actually does are different things. Yes, this is documented in the manual, and if I had sat down and read the whole thing before taking the light out of the box, I would’ve expected that, but this is not intuitive. Sure, there are other lights where turbo is part of the main group or you have to hold for off, but not being able to turn the light off directly from turbo is very unusual.

Here’s where things get a little interesting. Under the crenulated bezel, the SC32 uses a fresnel lens not commonly seen on flashlights. In a nutshell, the fresnel lens does the job of a convex lens by dividing up the curvature of the lens over a number of lower-profile concentric rings. This allows the lens to be flatter, saving space and material. Since this fresnel lens is shorter than standard TIR lenses or reflectors, it helps keep the light short. There’s no glass lens to cover the plastic fresnel lens, so that may shorten the overall length as well, but then the plastic lens is exposed, so keep that in mind.As always, I took my measurements at 30 seconds after turn on. The lowest modes didn’t quite meet specifications, but the fresnel lens proved its worth in the higher modes as I measured over 13,851 cd on turbo, pushing the throw 21 meters farther than spec!
