Black lights?

Hmmm, what type of bulb is it? There are black lights from incandescent to LED. In general I would not rely on these exclusively, but perhaps they lead to some interesting colors. A true black light has UV-A which is not visible and the bulbs usually have filters that make them visible to posters hanging in Spencer Gifts.


 
I saw a post on here about black box lighting and it reminded me of black lights. I dont have any on my tank but I couldn't help to question the idea.

LOL, just a tangent. It may give corals some glow, but it would depend on the light itself if it would give them any benefit.
