Welcome to the forum!
I would suggest trying out this glass top: http://www.plantedtank.net/forums/sh...ad.php?t=42194
I have wanted to do one and it seems pretty easy.
Then you can do something like a finnex fugeray LED. I don't know if the light will be too high for your purposes though. They are nice lights and have people on TPT use them a lot. Hopefully I helped a little!
