light fixture

So I've been meaning to try these bulbs but apparently they don't make/ I can't find any sizes to fit my light fixtures... I have a 24" fixture holding a 18" bulb and a 30" fixture holding a 24" bulb. Do they design these bulbs only to fit their Zoomed terrarium hoods to handle the higher...

i apologize if this is a dumb question but i just want to clarify before i purchase a fixture.. i can use a fluorescent light fixture that was previously used for a fish tank to put a UVB bulb in right? thanks everyone!

Hello everyone! Just wanted to ask if anyone has experience using the Exo Terra Dual Top Fluorescent and Halogen light fixture? I just picked one up for a really good price but I am not going to use it until I have my chameleon in his adult set-up. Have you had any problems with it? What bulbs...
