85 is way too hot you need to run some small fans blowing across the lights to help ventilate them.
I just adjusted the heater I figured it was the lights but the heater did get turned up somehow and on my heater there's no gauge just a turn knob that has no numbers so I'm waiting for it to lowerI like 78 as well. 85 is way to high, your inhabitants probably wont live long under those temps. Is that what your heater is set at? I don't see your lights bringing a 55 up that high unless your running MH and or the room temp is up there too.
What do u mean a control?I would looking into getting a heater that at least has a numbered dial. Or, pick up a control to keep your temp stable.
