They are also pygmys which most seem to think do not require UV lighting due to their "Low" place in life....I personally say CFL's are no longer an issue. The companies have stated they have been fixed. However you know some companies will say just about anything. I personally have started using Metal Halides over all of my Chameleons, it creates imo a better disposition, more activity and a better simulation of the natural sun. And it could double as a room heater!
