UVB Length....

[Bruce Wayne]

I have a 24 inch arcadia 12% T5 in 4x2x2 enclosure. I have read that a need the light to cover 2/3 of the tank. Do I need to upgrade to a 36 inch fixture or is my 24 inch okay?

TLDR: 24" is good.

24'' T5's are what I recommend for 4x2x2's. UV is important, but it's also dangerous. Having a 24" allows for there to be "shade" areas (low - 0 UV) in the tank. Being able to escape UV is just as important as having strong enough UV.

Thanks..another quick question. Is is okay for the hottest basking spot to be in the middle of the tank or should it be off to one side to create a gradual shift from hot to cool? Here is a pic. Does it look okay or should I move the lighting?

As long as your dragon is basking and having a cooler sides to go to like one spot 80's and another area in the 90's is good --
