Lighting bulb requirements help??

[charmander1234]

Hi can you please give me suggestions for lighting requirements for my 2 month old beardie baby.
I currently have a 20 gallon tank using
-Zilla slimline desert 50 UVB T8 fluorescent fixture
-75 W Basking bulb

is this sufficient? Please tell me if there is a better option I can purchase for him. He doesn’t have a strong appetite and I am thinking maybe to change his lighting .
His temps are 105 Basking
Cool side is 85

is the 75 watt day basking bulb ok? Should I switch to a 50 watt.
Any brands better than others?

thanks so much
