How Long Should My UVB Light Be?

Hi everyone! I'm currently putting together the "shopping list" of enclosure items that I need to get set up before we get our beardie (sometime in the next few months). The enclosure we are looking at is 36" long. How long should our UVB light (and fixture) be in relation to that? Does it need to also be 36" long? Or would an 18" or 24" long bulb work? Thanks!

Hi there...an 18 or 24 would be fine. A 24 probably better , obviously covers a larger area of the tank.

Awesome! The price jump from the 24" to the 36" bulb is really dramatic ($19 vs $37 on Amazon), so it'll be nice to be able to save a little bit there.

For most situations I think 24" is the best size. Even if it's a 6 foot long tank, what really matters is having the UV at the basking spot.

I just walked into my room and instead of looking at me, Swordtail's eyes darted directly to the ice cream drumstick I'm holding
Finally replaced Swordtail's substrate

What is a quick way to warm up a cold beardie? His heating element went out overnight and now he's very cold.
