thank a lot for the info.Filo said:The wavelength peaks from helogen lights do not correspond to the wavelengths
plants need. Also if the light is too intense you can cook your fish even before signs of algae form. Also note that halogen lights are not energy effient at all, I have heard it might cost as much as .10 cents an hour to operate...will you have it on 24/7?
I think this could be of great use, water proof, so you could prob get away with putting it in your tank! Not sure exactly how it all works, but take a look http://www.newlite.com/
