Do not get a fixture that is the same length as the tank - you want your dragon to be able to escape those rays w/ OUT having to hide from the UVB - if you want you can get a 24" or a 30" it is up to you --- I have a 24" in my 4X2X2 tank -- you can get the UVB fixtures from here these people are fast and very good they ship Fed ExMy enclosed is ready for lights. It’s 5’ long. I guess I need 48” of UVB or is it better to use 2 24”? Can u tell me where to order fixtures and which one and what tubes? Thanks. Can the basking bulbs go in any fixture or does it need to be reflective
