I can confirm the relative lux readings: FF STL-V3 gives ~150%of Keygos KE5, but ~50% of FF STL-V6 (my readings for these three were something like 17kcd, 25kcd and 50kcd measured at 2m and converted back to 1m)
Edit: There might be something wrong, since 17kcd for Keygos sounds a bit too little. Have to check again later.
..and I know that 2m is too little for real throwers, but that was the best I could do yesterday. (I was just curious to see if STL-V3 really outshines KE5 by that much, and considered 2m as "good enough" for relative throw figures)
I just got mine yesterday. Definitely nice finish. Yeah, I was measuring the tailcap amps and it read around 1.8 A on high which I was kinda disappointed with. Was really hoping the driver was actually regulated at 2800 mAh like it says, but alas it is not the case. Still really bright though. I was hoping this would be like the X9 but with a better driver that I wouldn't need to replace to get over 2 amps. So is this driver regulated or not? How to find out?
I would say @ 8.4v or 2x16340 etc , it would be regulated ...
With a single 18650 , probably not so
Test regulation - Buy a light meter , and a Multi Meter .. Test battery voltage and then test output , where output drops , flashlight falls out of regulation ...
Its only just dawned on me that this is supposed to be a (Q5) clone of the Fandyfire STL-V3. An XM-L mod of it may provide similar results for about half the price...
