3753203 200mW 532nm Single Dot Green Laser Pointer
Approximately how wide is the beam spot at full width when holding laser 6" from object?
Will this power always have heat or can you focus the beam wide enough that it does not feel hot at this close of range?

I think the green contains Kryptonite, effective against a wide range of superheroes.

I have several such 301, 302 green lasers. Some where rated under 5mW other above 100... but they seem very similar. I haven't tried much at very close range (mind your eye when looking at the bright spot) but i don't think they produce much heat - not enough to burn anything.

You can unscrew the front part which does change the focus, but this is not very convenient as the front part comes a bit loose and the focus can shift easily.

Nice laser for the price. Very bright beam at night, and it can run for hours on a 18650 - i use a laundry clip to keep the switch pressed on.
My location: Nice, France.

I advise against using a clip to keep the switch pressed. Your supposed to cycle strong lasers 1minute on, 1 minute off. I believe it varies slightly, but as a general rule, its a good practice.
