one or two uv lights?

[nightcrawler]

i used to only have one uvb tube light on top of my cage, but as of recent i have changed it to two. i also too a bunch of my fake vines out and pruned my trees so that my cham can move easier around because he is getting bigger. he has been browner then normal. i once put a 10 tube in thinking it will be better and he turned brown like this too. is they are two 5.o 18" tubes. he can get like 4 inches away at the closest spot. he getting too much uvb light? should i just put a normal tube light up there to light up the enclosure or should i just put nothing up there?

I think 1 UVB is enough, and there is no need for 2 of them.

I would only use 1 5.0 uvb bulb.
The other one I would replace with a regular tube light.
It will help to make the cage brighter and make viewing more pleseant for yourself.

You could also put a normal floursecent light in there to add brightness.

EDIT - Justin Carl just beat me to it.

They usually get darker like that to adsorb more of the uv, and the zoo' 10s can reach down to 20 inches into the cage so they say.
