Flourescents on timers for sake of regualrity (no breeding yet), red overhead as needed. If you are using a red light make sure that it is not coated etc - we tried to save a few bucks by getting red bulbs (just generic red bulbs) and noticed after about a week the coating was thinning and the coloration was shifting to orange and thus becoming visible to the snakes - janked that caca before they got stressed. It'll be warm enough soon we can forego the (red) lights altogether.
