i was just curious, if you keep this on for 12 - 14 hrs a day (for UVB), then do you just swap it out with a regular heat bulb to keep the basking spot, but provide night time cycle?

OR do you just leave it on 24/7?

AND does it need the basking spot 24/7?

AND
"Q: Can I use the rheostat/thermostat with a Reptisun, Avian Sun or Power Sun UV?
A: These lamps need specific line voltages; they cannot be used with dimmers/rheostats."
so how do you get the PERFECT basking temp? wut wattage gives what?

sry for the mouthful, i was just really confused lol. hit a brain roadblock when readn about UVB.
