I'm not mechanically inclined, so I'm a little confused by it all. I'm getting a setup with a 40-gal breeder tank with a T8 fixture and Reptisun 10.0 tube. Do I need to find a way to mount it inside the tank or will it be okay to put it on top of the screen?
The T8 bulb is not strong enough to provide adequate UVB through screen mesh.
That's why it's recommended to hang it inside the enclosure at a distance of 6-8" away from the dragon.
MAYBE, with a good reflective fixture you could get further away but not on top of the screen cover.
The T5 bulbs are much more powerful and CAN be used on top of a screen cover.
I was thinking T5 and T8 describe the fixture, not the bulb... ? If I want to keep the fixture outside the screen, do I need a new fixture or a new tube? Or both? :?
