The built-in thermal control automatically adjusts brightness output to prevent overheating. The "6" in the IP68 rating represents the level of protection against solid objects, specifically dust and foreign particles. It indicates that the Q8 Plus flashlight, is fully protected against the entry of dust and other solid objects. The "8" in the IP68 rating indicates the highest level of protection against water ingress.
Brighter: Q8PLUS will be brighter when using HD Battery, the battery link is https://www.sofirnlight.com/products/sofirn-1700-4000mah-10c-40a-hd-battery-made-of-lishen-lr2170la-cell Disclaimer: All of my measurements are taken at turn-on. Lumen measurements were taken on a Texas Ace 3.5″ Lumen Tube. A candela measurement was taken at 10 meters with an Opple Light Master III on the highest brightness, and other candela figures were calculated relative to that. CRI, CCT, & DUV data was taken for each mode from a few feet away at the center of the hotspot with the Opple Light Master and Waveform DUV Calculator. Runtime tests were performed with the Ceilingbounce app on my smartphone. All of these tests were performed with fully charged included batteries unless otherwise specified. I cannot measure moonlight directly, so moonlight readings are calculated based on the brightness relative to the next-lowest mode. None of this is professional equipment, so take all of these measurements with a grain of salt.The Q8 driver easily powers four emitters of any kind, in fact it easily powers 17 emitters in my Ham’r build. No need for three FET’s or 3 pairs of wires. I have a spare Q8 driver even now. Have used them in BLF GT’s to drive the SBT90.2. The blue charging indicators aren’t great either because they aren’t “glanceable”. To determine if my light is done charging I have to look at it for a full ~2 seconds to see whether the blue LED’s are blinking or not. It would be more user friendly if charging status were indicated by different colors rather than by blinking/not blinking. For example, if the LED’s glowed red when charging and turned blue when fully charged, I could glance at the light from the corner of my eye and know its status. That’s also generally easier to understand without having to read the manual. Carry & Ergonomics Q8 Plus includes six Cree XHP50.2 3V emitters in either 6500K or 5000K. I have 6500K. These emitters are designed for efficiency and high output, not great color properties. The lens does not appear to have any anti-reflective coating. The Sofirn Q8 Pro is not for the small handed. I am 6’2” and 215 pounds (Thanks holiday food!) and it fits well in my hands, but dwarfs the hands of my children. That being said, in my hands, it feels quite good. The knurling gives quite a lot of grip so I had no fear of it falling (again), even though it is very smooth.
This flashlight has an AR coated lens. This Anti-Reflective coating is a thin optical coating applied to the surface of the lens to minimize reflections and improve light transmission. The Q8 Plus utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches. Performance Flux The Anduril firmware is an open-source firmware developed for flashlights. It is designed to provide advanced control and customization options, offering a high degree of flexibility and functionality. The Q8 Plus has mode memory. Mode memory means that the flashlight will remember the mode you were using when the light was last turned off, and when you turn it on again. The ramping mode of the Q8 Plus is intuitive, and lets you seamlessly ramp the output up and down over almost the entire output range. The driver also has flashing pads, but they’re a weird layout (not the normal layout we’ve been seeing from Sofirn/Wurkkos on Attiny1616 lights so far). Sofirn, please stop changing your flashing pad layouts! It makes it a lot more complicated for enthusiasts to flash updated or modified firmware onto our lights. The Sofirn/Wurkkos factory has shipped lights with bugged firmware before so it’s important to be able to update!
Sofirn Q8 Pro: predecessor to Q8 Plus, four LED’s instead of six, four 18650 batteries instead of three 21700 batteries, I measured about half the output of Q8 Plus from Q8 Pro, stainless steel bezel Also above is the light beside my custom engraved TorchLAB BOSS 35, an 18350 light. I reviewed the aluminum version of that light in both 35 and 70 formats. Retention and Carry Astrolux MF01X: 18 small LED’s instead of 6 big LED’s, very different styling, comes with older Anduril 1 firmware, covered in slots for glow tubes or tritium vials, includes aux LED’s in the front
