yes, and is pretty nice too, mine takes 800mA on a fresh charge and keeps it that way a good 10mins, after that it drops to about 700ma, and settles between 600 an 700 for an hour or so, wen it dims noticeably, to about 200-300mA
Very smooth transition, and i guess it could not be any more efficient
I'l do a serious plot, when i'l can...
This is actually gonna be torn apart again and the head is going to be "definned" and polished... So no heatsink yet, but I`ve been "bursting" it and had it on for 20-40 secs at most and no heat..
