sofirn Q8 Plus Super Bright Flashlight max 16000 Lumens, Rechargeable Powerful Flashlight with High Powered 6* LED, Anduril 2 UI, Ultra-Long Runtime for Camping, Searching, Survival, Emergency

Product Information

USB Type-C Charging: USB-C connection for fast charging of three 21700 batteries, in addition, this powerful flashlight can operate as a power bank to charge other portable devices. 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. As far as the beam, well, it doesn’t really have one. It has an incredibly wide hotspot that, even at 6 meters, is already 2.5+ meters wide. This is in addition to the fact that it is very soft and blends in well with the spill, essentially giving it a full flood effect and just blankets anything you shine it at in light. Now the box indicated this was the 6500k variant (it also comes in a 5000k model), however, this particular light, using my Opple Lightmaster Pro at 10 meters, came in just above 5500k on lower modes but shot up to about 5900k on higher output modes. PWM: No PWM is visible to my eyes nor audible to my ears, but my camera could see it on Medium and High modes.

Tailstanding works great. The tail is wide and perfectly flat. That combined with the long runtime makes this light an excellent choice for ceiling-bouncing to light a room for awhile. I do wish the tailcap included a milled cavity inside for the user to install a strong magnet if they wish. Unfortunately Sofirn made no such allowance. Batteries & Charging

Unlike the Sofirn Q8 which has NarsilM, but like the Q8 Pro, this Q8 Plus has the Andúril2 user interface. Charging is facilitated by a USB-C port on the side of the light. It’s covered by Sofirn’s excellent port cover they use on many of their lights. It’s the best rubber port cover design I’ve come across. USB C-to-C charging cables work fine and it can also function as a powerbank. Charging from empty took six hours from a 5V 3A source which is pretty slow, but supporting USB-PD charging protocol for faster speeds would increase the price so I can live with the slow charging. The light can’t be powered by the USB port alone. The batteries must be installed for it to work, but it can be used while charging which is nice. Competition

The switch is configurable, according to the manual. You will need to be in Advanced UI to configure the switch!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. I find that these fin edges to have anodizing that’s a bit frail. Just a bit of usage and the anno will probably begin to wear off. Below you can also see the stainless bezel. This bezel has a bit of shape, and that’ll allow light to escape when headstanding. 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 ANSI FL1 standards: The runtime is measured until the light drops to 10% of its initial output (30 seconds after turning on). This does not mean that the flashlight is not usable anymore. The last column shows how long the light actually works till it shuts off. If there is a + symbol, it means that the test was stopped at that particular point, but the light was actually still running. This happens on certain occasions, with certain drivers, firmware, or batteries. Peak beam intensity and beam distance measurements Mode

Here’s a better look at that cell holder. The cells are surrounded by aluminum very snugly. This seems like it might be just for holding the cells in place (and it is!) but it also serves to move the heat generated from the cells when the light is in high output directly into a fairly good mass of aluminum for heat management. 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. Smarter Indicator: with green/ blue/ orange/ flashing led indicator to inform us about changing modes or charging status I am putting this in a table here with ToyKeeper’s permission. Thanks, TK! This is so much better than me writing it because it’s more reliable, and I completely trust its accuracy (at least, if I can paste it accurately). I’m breaking it up a little differently than ToyKeeper did, though I certainly understand why it was done her way originally.The overheating aspect of it when it’s on high/turbo setting is ridiculous. It gets hot fast, but it gets uncomfortably hot after about 2-5 minutes of constant turbo mode. Performance: Turbo is very very bright for a few seconds after turn-on and it gets hot very very fast. High mode lasts a respectable 3 minutes at 4000 lumens before stepping down. Medium runtime is a very impressive 14+ hours. For the Turbo Cooled test I raised the thermal limit to 70C (the max allowed in the firmware) and directed a desk fan straight at the light on its highest setting.
