I just installed my new T5H0 with a 10K and Blue bulbs for my 55 gallon Malawi tank. The tank is set up without the lid or the glass cover. The light sits on the provided brakets that attache to the rim of the tank. The light it produces with in the tank is nice, However I am not to fond of the light that shins outside of the tank. Any ideas on how I can reduce the amount of light that shines outside of the tank?. Thank you
