Being a LED - and OBTW - the White light LED's are purple ?!
They might help. - who knows.

I'm game to try with a CCD - Have camera and plan on getting LED Club...
I'll buy a white flashlight they have on the same page and test that
as well.

I also have a sterilizing 254nm out in the shop If I still have it -
I might have given it away with my old eproms.

Wonder on the corals.
