Zoo Med Ceramic

for my ball python in his tank the Heating Pad under the tank only keeps that spot at 73ish, making it hard for my ball, having him stay in his hide cus its the warmest area. so

durring the day from 6am to 6pm i have a zoo med 150watt Ceramic Heater on over 1 side [hot side] that is kept at 83-86 degrees in his hide, and about 89 90 degree Basking Spot. and at night, would it be safe to bump down the temp on the basking ceramic heater light so it keeps a temp ov about 75-78 degrees. making it easier on my ball, he will like to move around at night if not it is not only warm in his hide.

basically. should i leave my ceramic lamp on 24 hours. and lower it at night? safe? no?

thanks.
