UV LED over tank

[Jaws]

I'm not too sure what wavelength my Royal Blues operate at unfortunately but I know that I purchased them from Milad when he did his group buy at the beginning of last year if that helps.

Through Milad, he sells a 3W Exotic True Violet LED that ranges from 390-430nm. I've got a couple to put on my build but haven't had the time to start putting it together yet to tell you what they're like.
