I'll have to get another therometer as the other broke, but right now I have a double sided lamp, one side with the 100 w desert bulb and the other with the 150 w night bulb, both on right now.
Assuming we are talking about an adult (Over 1.5 years old) beardie, a 40 gallon is a bit small unless you have a small adult. A 75 gallon at minimum for adults is best, not just because of the floor space, but prevents burning your beardie with the UVB strip if it a has nowhere to escape or go under and a better temp gradient.

Hot spot should be about 90-95F, some people go higher for adults but many including myself stays within this range. Either way, higher than 100F is an overkill.

Cool side should be no lower than 77F. They can do okay at 75F for a few days but preferred to stay within 77-80F. Room temp usually can cover that.

STOP using the night bulb. Lizards, including beardies and BTS, can see light even those red light bulbs or other night bulbs. This can stress them out and disturbs their rest. When it is night time, turn all lights off in its tank so it can sleep better. The only time you will turn anything on at sleep time is a CHE for additional heat, usually in the winter. Again, turn off your night bulbs. Ambient light is fine.

Is it 18 inches from the basking spot to the lid?

I will tell you more about the UVB later.
