The tailcap was only unscrewed as the light was locked out, and forgot to screw it back for the x-ray image.
The maximum cell length permitted is 67mm which realistically means that only unprotected cells are allowed in this light.
The springs are very compressed even with 65.2mm batteries such as the GA (in the image).
I could fit a button top added VTC6 at 66.5mm.
Oops, didn’t see this review until you shared the link elsewhere. How did you get the x-ray image?
Some of the things on your “didn’t like” list are already fixed in newer firmware, but I don’t know if/when Hank will use it. Perhaps it’ll happen eventually (particularly if I finally update its thermal code again).
Love that X-Ray image! Shows the correlation between all the parts, even the junction of threads, really cool seeing that without having to be a cut-away.
Standby drain should be lower than the cell’s self-discharge rate. I measure 21 uA on mine, or about 16 years of standby time per charge.
After I’ve reflashed with different code and fuses, I measure 0.31 uA, or about 1100 years of standby time per charge.
I generally use mechanical lockout on the stock firmware because I don’t like clicking six times and then waiting for two slow flashes… but after reflashing I use soft lockout instead (4 clicks and a single fast blink).
I have a nearby open space with 220m clearance. Unfortunately the my last two attempts of using that space were thwarted for various reasons (flood and people rugby training in the pitch black). So hopefully sometime soon I’ll have a longer distance shot. Given that my L6 has a useable beam (as in being able to discern objects) for around 200m, I would expect the beam to be useable for over 250m.
That depends on how much light you want on the target, I like about 1 lux on my target to be able to actually see it, so about 350 yards or 1050 feet. Real world experience seems to bear that out for me.
I really hope that Hank adopts your new firmware! That’s one of the things that’s keeping me from getting an Emisar now, but sooner or later I’m bound to cave in.
(I know I could reflash, but I’d prefer not to until I’ve practiced a bit on other lights.)
