i do plan on getting a t5 10.0 bulb for my tank soon, but since i bought this guy as sort of a bundle deal the previous owners had this light on top of the tank and i just recently moved it to the inside. It’s a t8 18 inch. But i think a t5 10.0 would be too strong to mount on the inside since the tank height is only 12”. Anyone that can give me advice I’d appreciate it thanks
A T5 would still be OK if you mount it above the screen. That looks like one of the Exo Terra tanks which has a pretty fine mesh top that will intercept quite a bit of the output. A T8 isn't very effective through that mesh but a T5 would be really good at about 8-10'' above the basking area based on my measurement. Without a screen top they are ideal at about 12''.
