Solar lighting for your tank

[spreerider]

I just read the entire post, especially about putting them under the surface, the company i work for makes underwater lights to light up fish farms and extend day length, the reason we use underwater lights and not surface mounted lights is that the surface of water reflects about 40% of the light unless its directly shining downward but that wouldent light a large area well so we put them under about 10ft and one light lights up a 25X25 area like daylight and those are only 400w with 1000w or 1500w we get about 50X50. so underwater you would get alot more light from a source but you would also get all the heat.

i would have posted on reef central but dont have an account.
