Black cham??!!

I would say if you are worried about his night time temps it may be worth investing in a infrared heat bulb to use at night which will emit heat and not light so not disturb his sleep pattern. However it is healthy for chams to have a drop in temps at nighttime and it may be worth just keeping the room he is in warm during the night.

The only heat bulb that emits no light is a ceramic heat emitter. The infrared bulbs do create visible light. Also, I'd change your UV bulb...they only last for about 6 months anyway.
