My son has a baby beardie (about 9 weeks old). He is housed in a 40 gallon breeder. Currently, we are using a 24" Reptisun 10 t8 bulb in one of my djay black light fixtures (has a reflector). The bulb is approximately 8 inches from the surface of his basking spot. Depending where he lays, it can stretch out to about 10 inches. Would I still benefit from upgrading to the t5 bulb? If so, do I need to move it a little farther away? I do have a bulb and fixture on order from lllreptile if I choose to change.
You really wont get much of a benefit from the stronger bulb as your distances are good right now. The t8s do perfectly fine in the 40g tanks under the mesh. In larger tanks or setups where you need to mount ontop of mesh, the t5s come in handy.
