They look really nice in a tank but i know theres awith draw they burn out to easily and is really hot i think but other wise there nice i think. Sombody tell me if i am wrong ir right or tell
I used a black light in my tank for a year. If I remember right it caused alot of algae growth and I read it was not good for the fish. Plus it really doesnt look as good in the tank. At least thats my opinion.
