I have completed 3 pen builds, 405nm 150mw, 445-450nm 4000mw, and 532nm 100mw. While burning things at 10 feet while lying in bed is rather cool, I much prefer the 532nm pen. Not only is the 532nm the brightest of the three, it's just really a sweet color.
this is very necro.. Some suspect he/she was only a troll.
Pretty wild stuff-- twilight zone wild.
