hello all,
Just trying to figure out if this will do for now, or do i have to change everything around... even though i swear i have tried everything.
my basking spot is located on the right side of tank, & cool side is left. The temperatures are perfect and my lizard is a happy camper.
The only thing is I have a exo terra compact top with 2 150 26watt UVB bulbs and 1 CFL for lighting. The uvb bulbs have worked perfectly for me, so I don't plan on changing to tubes anytime soon. (I've had my lizard for just under a year and no problems). BUT I can't seem to get the UVB very close to the basking spot. although I do notice my lizard spending his time between the UVB "basking area" and his actual basking hot spot. is this okay? or should i try and move my UVB closer to my basking spot. I have a CHE near my uvb but it doesn't obviously get as hot as a basking spot gets too. the UVB is about 12 inches away from his basking spot and 6 inches away from the CHE.
The UVB should be near the basking site. Think about the sun, it's a package deal. Heat is an important part of the process to synthesize D3. UV bulbs also emit UVA wich is useful for color vision in reptiles so having the light sources all near each other helps the dragon see more accurately. Since you have the CHE there it may be ok (I worry about how close it is though).
Part of what makes the tubes better than the compacts is that the light is spread over the length of the bulb. You can make a gradient and ensure the dragon can fit it's whole body into the exposed area. Not that compacts are dangerous like years past but the UVB doesn't reach out very far from the bulb in any direction and overall is a weaker exposure.
