Just got this from Mr.BrightLights (thx for the super fast shipping! will definitely deal again)
Initial test on my PVC LMD yields 21, 210 & 640 lux (lumens). Again, I'm not claiming accuracy but I think those are very realisitc numbers. Overall fit and finish is OK, too bad the fins doesn't match rest of the light. Nice neutral color (although slightly warmer than I prefer BUT it's by no means warm either). Fits nicely in the hand. I'll try to get to a full review in the coming weeks but Foy has already put up an excellent one on a Stone White (which I have incoming as well).
Also got four MOLI18650B bats (thx again for the heads up viktori!). On the charger now and will conduct some runtime testing (and whenever I get my hobby charger set up, some discharge testing). If these hold up, they'll be awesome bang for the buck!
EDIT: Also got this a few days back and already putting to good use:
I used to have a 120V clip on fan but it was noisy and likely nowhere near as energy efficient as this little USB gem. It's got a 4 port hub to boot. Has already brought some sanity and peace/quiet while I'm conducting runtime testing for Turbo/High modes and is also great for visualizing PWM effect when you dial it down to low speed.
