Re: My first impression of my new laserglow 300mw
Lasers are pretty picky about the color they hit.. walls reflect a tremendous amount of energy thus protecting them pretty good..
now if the wall was red or black..........
But as distance increases, so does the width of the beam and so the heat and power density is less too...
A match is not igniting just merely by a fuel reaching ignition temperature such as paper or such, but a match has the flammable properites that causes it to have easy explosive type ignition.
I can also burn a hole in regular cardboard too.. but it didn't' ignite... simple looked like the end of a lit cigarette.
In fact it brings smoke to literally anything I hit thats a darker color... but thats within two feet or so...
I never leave it on the wall or anywhere else over a second or two...
I would never turn it on and walk off for a while even hitting the wall.... its a pretty hot beam.. but remember its light.. so that light has to be absorbed to do its damage.
