Beardies only need about 12-14 hours of UVB to keep healthy. Also, they don't need any visible (white, red, or otherwise) light when they sleep--in fact, it might make it harder for them to sleep! You can get a CHE if your house temperature drops below 65 degrees at night, but otherwise the beardie will do fine sleeping without one.
Personally, I bought a $10 electrical outlet timer to turn my beardie's lights on and off from 8am to 9pm, so that I don't have to worry about it during my day. They can be bought off of Amazon or at Walmart. It's seriously one of the most convenient purchases I've made!
Good luck with your beardie!
