Hello and welcome to FF! Maybe you can go to local store and check. I do know that the 12 in. ZooMed top fits the 12 in. ExoTerra terrarium). Fit is not as tight as their branded top and there is a small gap; but it rest well without wobbles.

Myself also prefer the ZooMeds because of individual switches (on 18") and higher capacity bulbs (60W versus 25W). Good luck !
