I don't know. Its big enough for my heat lamp, but i don't like using it because it sucks the humidity. If this new setup can keep my tank warm enough, then no. Is there any other way i can get the temperature up? The basking area is nice and warm with a UTH, but the ambient temperature is only 70-75. Although, she hangs out in the cool hide or wrapped around the water bowl almost as often as shes under the warm hide with the UTH.
