Interestingly the Highest of the stepped modes also steps down pretty heavily, again to around 200 lumens. I don’t observe low voltage protection when testing with the bench power, but I’m assured Andúril has it!

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. 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.The other accessory it comes with is a lanyard, but the only place to attach it is onto the end of the clip, which is closer to the head than it is to the tail. This sort of makes sense, as it allows you to rotate the light between standard and overhand grips, but it doesn’t really allow for the cigar hold, and you wouldn’t want it dangling by this.

Enhanced Color Rendering: The Sofirn SC32 HCRI flashlight is equipped with a high-quality Nichia LED featuring a high color rendering index (CRI) to provide accurate and vibrant color representation, making it ideal for tasks that require precise color identification.

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

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.Measurement disclaimer: Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable. What’s Included Versatile Lighting Modes: The SC32 HCRI offers multiple lighting modes, including moonlight, low, medium, high, turbo and strobe, allowing you to choose the appropriate brightness level for different tasks or environments.
