4ft melamine cage lighting size (for beardies)?

Hello,

I was just wondering what length fluorescent fixtures are most commonly used in 4ft cages? I can either use a 4ft fixture (diagonally acros the top) or a shorter fixture straight across the top center. I think the shorter one will look nicer but don't know if I'm better off with more light with the longer one? I've seen plenty of cage pics with 24" bulbs and would like to know if you feel they provide plenty of light? I would try to go with a single bulb fixture too to reduce bulb costs and the bulb lengths are pretty much all the same cost anyway. I will be using Reptisun 10.0 bulbs and the cages are for beardies.

Thanks,
Glenn

I have 24" fluorescent bulbs in my 4' cages, and 18" in my 3' cages, but those run across the back, in addition to a single bulb on one end to create a hot spot.

Thanks for the reply Matt!

Does the 24" light up the cage enough?

Thanks,
Glenn
