ok one more question lol i'm getting the lightin gat the moment gonna get a reptisun 10.0 but was wondering how big?? my tank is 4ft long by 18" wide by 20" high. would an 18" buld be to small? or go with a 24"? also for the heat lamp what size would be best for that? and how far apart from each other do they have to be? and also how high up to? i see some people put them ontop of the lids bu tothere place them inside closer to the bottom?
Get it as big as you can. A full 4 ft would be ideal, but at least a 3 ft. The size of the heat lamp just depends on several factors: how big your tank is, how far the lamp is from the basking spot, what your house's ambient temps are, if there are any drafts, etc. Your tank is pretty big, so I would say at least a 100w, maybe a 150w is needed. You can use just a regular household bulb, so you can get several wattages and experiment to see what works for you.
Also, for a long tank like that, you
may need a second bulb to keep things warm enough. I have a 55g, which is 4ft long. I have a 100w basking bulb plus I need a 40w bulb on the "cool" side to keep it warm enough during the winter.
You want the UVB to be as close to the basking bulb as possible so he soaks up UVB as he basks. And he needs to get within 6-8" of the UVB for maximum benefits. You may need to mount the UVB down inside the tank instead of sitting on top to accomplish this distance.
