I'm not gonna read the previous 200+ pages of fail (at least not all of them) so forgive me if this is a duplicate, even though I'm sure it is.
I have some high power DLED's for sale! They emit probably around 0.005 to 0.1 lumen each with only 100mA - 1000mA input! Quite the accomplished fail, if I do say so my self.
I saw a video of one of those lasers being profiled using an acrylic block. This thing was BIG. It only took about 2 seconds to burn a 2" deep x 1.5" diameter hole. It had to be many kilowatts.
It must have smelled like a crematorium when that guy decided to be part of the block.:barf:
