I can build some that could be plugged in sure.
But the batteries are no more expensive than a flashlight battery.
The maglite use 26650 x2
$8 a piece.
The zasers use 2x18650
I can even do 1w blues that use 1 18650. $6 battery is fine.
And the duty cycle to keep the high power laser cool will never let a true unlimited run unless it has active cooling. Maglite have been built with fans and tec cooling, but even they need to rest to cool down.
I actually have my own thread now. Tmack customs,
In the laser section.
Because of the title of this thread, I decided to start my own thread
I don't want people to think it's all about burning. (although it is fun!)
