Question About Viv Lighting Plz help!

[brazilman93]

I built my new beardie a new viv last week (the viv is 4 feet long, 2 feet wide, and 2 feet tall), and i had a question about the uvb lighting. I have two reptisun 10.0 that are 36 inches long, and i wanted to know if for the size of my viv if i needed only one or two uvb lights in the viv, i was thinking about putting both in but i read a post about how to much UVB light can cause bearded dragons to get something bad like a sun burn. So should i just have one UVB light or should i use both? And by the way the lights will be lowered with a mount so they won't be two feet away from the dragon, they will be about 15 inches away.

From what I understand, you would only want to use 1 of the Reptisun 10.0 UVB bulbs. Too much UVB is just as bad as not enough UVB.

I have heard of too much UVB, but I don't think a reptiSun 10.0 can over do it... Otherwise, Mercury Vapor Bulbs would be dangerous, as they provide much higher levels of UVB...

I think two, stretching the length of the cage would be fine, but two of them running parallel the length of the tank would be overkill.
It might be cheaper to just get the longest tube they offer and replace your fixture.
