Can anyone tell me if you can use a zoomed or exoterra double dome fixture (like this one https://www.amazon.com/Zoo-Med-Combo-Deep-Fixture/dp/B005KPMCPG) for a 50 or 60watt Arcadia heat projector? Or do I need a special fixture? I can't find clear information on this. Also, when using a Che or heat projector should it be over the basking area? Or is there a better spot? I would think distance from the bulb would matter. What are your thoughts?
