Hi! I've been searching for led flash light, I keep seeing this 10,000 watts led flashlight powered by 1 18650 batt. What do they mean 10,000 watts, do they really mean 10,000? is that possible?
Err, no!
Mind you, it depends on what you mean by a "flashlight".
A 10 joule photoflash, if it discharges in 1 millisecond, will in fact produce 10 kW during that 1 millisecond, and of course can readily be powered (charged) by batteries.

This says they exist so it must be true.

Note the extra handle so you don't burn yourself on the case.
Do you get spare batteries to reload every 10 seconds?
