@GwynT said..."Unless your house gets extremely cold (think sub 60F), you don't need heat. You need a linear UVB bulb for UVB during the day, and no light at night"...I think this comment needs a clarification...you don't need heat AT NIGHT unless your house gets extremely cold...you definitely need a UVB light and a basking light during the day (for veileds and Panthers and a lot of other species...caution with babies).
