I've contacted the seller for more information (beam angle, etc.) but he said he doesn't know anything about them since he's never used them before. But he did redirect me to Nichia's homepage, but when I look through their spec sheets, I can't find anything about the blue-green ones. I was hoping they were the one's that Craig mentions on his website, but I don't know for sure if they are nichia's. Also has anyone ever bought anything from this place?

I've already got an old mini mag just waiting for this conversion, I think I can fit about 7 of these in there with a little grinding. someone else on this board has alreday done the same thing, but I can't find that post anymore.

These appear to be Nichia NSPE590S.

Wavelength range: 495-505nm

Beam angle: 4° by 6°

Beam configuration: moth wing or "stealth bomber" with annular artifact.

Usefullness: Does not do well for use in flashlights, because the beam is too narrow and well-defined.

You will want to look for NSPE505BS or NSPE510BS (30° and 45°, respectively).
