I just did this. Build the cage and add basking spots and ledges. Usually the highest is their favorite. Keep it about a foot to 18 inches from the ceiling. Big enough she can lay and turn around on. Buy 2 4ft zoo med reptisun 10.0 you can then take those to a hardware store and get a fixture that can be mounted to ceiling and has a on off switch or pull cord. That takes care of uva/uvb rays. Set it up ever her favorite basking spot. Keep it just over her head.
