In case you aren’t aware, it’s not easy to measure lumens. You’d need to build something like this or buy one.
Also, lumens are perceived logarithmically, where you need 4x the lumens to perceive 2x the brightness. So a 100 lumen difference at 1000 lumens is perhaps imperceptible compared to a 100 difference at 200.
Additionally for turbo max lumen modes, some flashlights drop a fair amount within the first 30 seconds or so , not everyone measures or reports at the same time, etc. And then after that, most will step down after a few minutes. Measurement wise, some use the ANSI and measure at 30 seconds, others report the max lumens at turn-on. Battery condition, temperature, and manufacturer variation, etc. can all effect this as well. Many view the “few minute turbo” as not all that important, but rather the sustained output, which can be seen with runtime graphs. Here is the SP10 V3, which should be similar, though a bit brighter than the SP10 Pro, at the cost of all the flexibility that Anduril 2 gives you.
Anyways, I’ve found one other lumen measurement for the SP10 Pro: The YouTuber Smothered Chrome measured lumens at turn on of the SP10 V3 and SP10 Pro, which got 1075 and 896 respectively (877 with a less fresh battery).
