As stated above, they’re in a parallel configuration. That means the driver is expecting 4.2V maximum. Parallel means that the voltage input is the same voltage as one cell (4.2V max) but the capacity adds together from the for cells. The included cells are 5000mAh, so when full, the “battery” (cell holder) is really a 15,000mAh battery.
Note: Normally before testing Anduril lights, I have to calibrate the thermal sensor. Fortunately, this light comes pre-calibrated from the factory! All tests were run with the thermal ceiling at the default 45C. Usually I like the default 45C, but during my testing I found the light got warm but not hot, so you could increase the thermal limit a bit and still be able to hold the light if you want. 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. 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!
PWM: No PWM is visible to my eyes nor audible to my ears, but my camera could see it on Medium and High modes. Why those modes? Anduril 2 has 150 levels, so doing measurements and tests for each mode is virtually impossible. I’ve got this light set up how I like it with 5 levels. Bottom of ramp is level 1 and top of ramp is level 100. I’ve set up the stepped ramp with 4 steps so, with turbo added, I get the 5 modes I like. After testing, I raised the ramp ceiling to level 120 to get the middle modes to be a little brighter. 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
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 Here’s a UI table! This table is directly from ToyKeeper’s Andúril2 manual, which you can view here: Thermal regulation: works really well. Anduril 2 has some of the best thermal regulation available. It actively raises/lowers the brightness of the light in response to temperature fluctuations to ensure you get as much brightness as possible without overheating. Does anyone know more about whether different emitters are used in the Sofirn iteration and if so how they're differing from the ones in the Astrolux?Did already someone get his hands on both so the discrepancy in flux can be confirmed by one person using the same equipment?Another great way to tell, thanks to a reader is to see what the lowest level of ramping is. Advanced UI has a quite low low. Simple UI has a much higher “lowest level.” LED and Beam 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. The entire light is built differently, no idea why it’s called a Q8 at all as it’s different in virtually every way. The box is the same as most Sofirn products: basic thin cardboard with some foam and bubblewrap on the inside to protect the light. It’s not fancy but I’ve never received a damaged light from Sofirn. The following items are included in the box: 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.
Well, the output from the Sofirn Q8 Plus flashlight is quite fantastic, first of all. I don’t just love 6500K but that’s what Sofirn sent, and I do appreciate the high output numbers. The user interface is great, of course, because Anduril 2 is great! The e-switch is very nice, and USB-C charging works well, too. I’m disappointed we lost the powerbank feature that the Q8 Pro had, though. Long Review The Big Table Sofirn Q8 Plus flashlightThe Q8 Plus is tactical strobe ready. The strobe light is disorienting to the person it is aimed at which makes it difficult for them to concentrate. It has the SOS beacon function for an emergency situation. The SOS flashes Morse code so you can signal for help when needed. The SOS signal is recognized as an international distress call and is used to indicate an urgent need for assistance. Features Battery The switch is configurable, according to the manual. You will need to be in Advanced UI to configure the switch! 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 Regulation on the settings I used was about what I expected. The higher modes are not regulated and the lower modes are. You just can’t get great regulation on mega flooders like this, regardless of the type of driver they use. They just pump out too many lumens from too few batteries to be able to well regulated. The tailcap is removable, but there’s no point; it’s a dumb tailcap. I don’t believe it even carries any current. So while it’s removable (maybe in case you want to do maintenance on the inside or something), there’s no need to do so.
