New tank- what do I get

I have a 2 year old bearded dragon who primarily stays at my dad’s house (since we got him) but now we are setting up a tank at my mom’s too and we are both clueless on what to get. He’s currently living in a 55 gallon (planning on getting bigger) at dad’s and going to get an 81 gallon at mom’s. Dad handles all the tank stuff so I would really appreciate help on what lights to get and what accessories.
