Do a search for lighting,i know there are atleast a dozen threads about it. But as far as i know aquarium lighting isnt recomended for housing chameleons, it also depends on conditions ie temps. But i know for sure you are going to need a uvb bulb (recomended) the linear tubes like reptisun 5.0 and depending again on age and conditions a light for heat. Fill out a how to ask for help form so that everyone can tell what you have for the enclosure so far.
