Wouldn't that overdrive it? I assume they're handpicking them based on forward voltage.<HR></BLOCKQUOTE>
FWIW-If it was me, with that light, I'd probably try it out carefully, watching closely for the telltale signs i.e. color change, getting hot etc. Some units are forgiving and some are not.
So, kinda hard to judge... current issue Luxeons being as they are.
What I did with my 4-AAA DB modded white Luxeon was to "sneak up" on it -voltagewise, first trying 2.5v, then 3v. then 3.2v etc. until the head of the flashlight got slightly warm-which happened after 4 minutes operation.
I noted that if the head of the light was warm, then the LED itself would be hotter. So I was kinda conservative at the time.
This was way before other CPF people started hot-rodding their Luxeons above 750mA+!
To cut to the chase, I now run that 1 year old light at 550mA with 3 x 1/3AAA NimHs and notice very little heating at all-but then this flashlight get used mostly just for a few minutes-short bursts at a time-it does
belt out a lot of light. Also, no measured loss of brightness when I occasionally check it with the meter. I think those small batteries self-limit the available current though...
p.s.Lux-about that photo on the bottom of your posts..is that you, or Gene Hackman?
