sofirn SC32 EDC Flashlight 2000 lumens, Small Rechargeable Flashlight with Super Bright SST40 LED 5000K, Tail E-Switch, Pocket Size Flashlight for Camping, Hiking, Dog Walking Emergency

Product Information

I measured Lumens using my 30 cm integrating sphere with a Digi-Sense 20250-00 data logging lux meter that’s been calibrated with several lights of known output. Tests were conducted using a fully charged 3000 mAh 18650 cell using the stepped modes (not smooth ramping). Amps and output were measured using the included cell, but to evaluate the light’s full capabilities, I also tested it with a Sony VTC6. Mode There is also a USB-A to USB-C charging cable included, which is a good one to use, as the charging port is recessed and in somewhat of a tight space. If the plastic head around the USB-C plug is too wide, it won’t fit. Medium was about as exciting as a game of Bingo at the local grange hall. Medium doesn’t fall under a regulated mode at 740 mA, so it’s still running on a MOSFET or some other regulator using PWM. The test started at 305 Lumens, and that didn’t change much, with gradual decreases in output as the battery drained. The output didn’t drop below 200 Lumens until 3 hours and 5 minutes in, then down to 150 Lumens by 4 hours 20 minutes, and under 100 Lumens by 5 hours 2 minutes. The output dropped to 72 Lumens before dropping off the scale at 5 hours 24 minutes. Sofirn’s wayyyy off here with their 7.5 hour runtime, but this is still a good figure. The light never got over 40 C the entire runtime. 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. 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.

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. Powerful Performance: The Sofirn SC33 is equipped with a boost driver, delivering impressive performance and maximizing the output of its high-quality LED. Experience enhanced brightness and performance.Yes. The LED indicators in the side switch will flash red rapidly, and when the battery hits 3 volts, the light steps down to a very low level. After a while, the light will shut down. Another thing that’s a bit annoying is the jump between moonlight and low. The difference between low, medium, high, and turbo is ok, but not having anything between 1 and 90 (advertised) lumens is jarring. If you think accidentally activating a 10-lumen low mode when you’re expecting moonlight is bad, hitting low on the SC32 will leave you blinking for a minute afterward. It’s no better with the smooth ramping mode either, since it’s very hard to get into a level below the stepped low level. Lumen measurements (for each mode) Mode The bezel is very toothy, and I suppose is what lends the “tactical” side of things to the name. Otherwise, I am not inclined to consider this light a tactical light. EDIT: Many people have reminded me that often Andúril needs to be calibrated to allow the light to function properly. I don’t disagree, but I also think the light should function correctly out of the box. If it doesn’t, then this isn’t a light suited to beginners, or people unwilling to calibrate. Calibration isn’t hard, but it’s very specific. Type-C charging: With the built-in USB-C charging port, a 18650 cell can be charged inside your light using the included USB Type-A to USB-C cable, freeing you to enjoy your day and being able to charge practically anywhere. A full charge takes approximately 2.5 hours using a 3300mAh or 3.3Ah 3.6V 18650 cell.

I think this alignment of the switch LEDs is pretty normal… if you’re expecting them to be on… some… other axis, then this might not be the light for you. 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 Here’s my UI table! This table doesn’t cover the aux and switch LEDs, but they’re somewhat configurable too. StateTo ensure that you get the desirable product, we allow a seven-day product return period. Any product return application outside this period will not be entertained.

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). The Sofirn SP35 flashlight is now available with advanced temperature regulation (ATR). Read on for testing on this high output flashlight! 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.Long-lasting Battery: With its efficient design and utilization of a single 21700 battery, the SC33 can provide extended runtime. Experience up to 11.5 hours of continuous use on the low mode, allowing you to rely on this flashlight for prolonged outdoor adventures or emergencies. There’s just one version of the Sofirn SC31T tactical flashlight. It’s available with or without an 18650 though. Of course, there are other SC31 versions, including the SC31 Pro which I have reviewed. Also, just a regular SC31, which I’ve also reviewed. Price Here’s a UI table! There are two groups on the Sofirn SC32 Mini Tactical flashlight. That’s another way (probably really “the” way) that this is a tactical light. State 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.
