Well, to be fair they serve little purpose for projectors - which is what most of them are there for.
I think there are more people on LPF in it for the science of lasers, and these diodes would change 473nm handhelds, allowing smaller builds.
At any rate - thanks for the find BP!
Also, just so everyone knows. I will have to press this diode into a module and solder on leads to test it. Whoever receives it will get it in a copper module.
