I suspect this has been tried by a lot of flashaholics here.
What is the general assessment, and would it run for an hour, for instance, on low mode? I know the high mode would get too hot in a few minutes.
What is the output on the low mode, and how long will it burn with a Trustfire 3000 Mah battery?
It looks pretty good for a cheap, but reliable? light.
I like hollow pills. that much easier to insert copper, as you did….if i remember correctly. if it pulls 3.5a on high I might actually stick w/ a stock driver for once
