The next LED revolution is upon us, and it is ultraviolet

[Aqua-Digital]

Ron is right! Even though MH pump out harmful UV the lights "should" have a UV glass on them.

I would not go near this!

Another reason why LED's that are UV only go down to about 380-390 much of which if not all is filtered out by the shield.

Its quite a myth that UV from aquarium lamps gets to the corals, the name UV came from T5 tubes where they adopted the term to market purple colour.
