I get the Arcadia 12% HO tubes in a reflector hood from Lightyourreptiles.com. They are very strong so its best to use a meter to gt the mounting height correct, but usually somewhere around 18-20 inches will do it. I only run the UV bulbs for 1-3 hours mid day. That's all they need. I run the basking bulbs and ambient light for 12-13 hours, and any ambient heat is on a thermostat.
That's exactly what I'm looking for. I'm assuming ambient can just be some full spec leds like you would use on a fish tank.
