Well im pretty new to tree frog keeping so let a few more reply's tell you the best option this is just the way I handled it. I bought a a red bulb for night time viewing of my red eye tree frog. Every time you turn on the lights the frogs slit pupils dial ate meaning they become round because of the quick intake of light. Its like when you just come out of the dark movie theater. You see all these funny purple spots and the light hurts. So I think the best option is to buy a red night viewing bulb there around ten dollars at pets mart and my red eye is active and is comfortable with this its real dim and doesn't seem to affect them
