How high do you elevate it?I personally use it and like it, BUT everyone is right- it gives off ALOT of heat so it typically can not be too close to the cage in fear of burns\eye problems. Otherwise, I like the simplicity and durability of it. It works for me.

Separate uv and basking bulbs are recommended and are better. With these you should still use a linear uv tube alongside it. This allows the chameleon to get uv without having to sit under heat all the time. The chameleon won't always want heat and uv at the same time.
