well good news, i had an old 150w flood light that in am going to use in the day, then put his 60w ceramic heater in at night. His terrarium temp is approx 100F in his basking spot and 79-85F in the cold end. After installing the new light he ran over and started to bask in the light. After about an hour i gave him a salad and he decided he was hungry. He has had an increased appetite and been MUCH more active since i put in his new light. I think the tank was too cold and he was trying to brumate. Thanks for the advice and has anyone tried the self ballasted lights from reptileuv.com? I was thinking about getting this for his tank http://www.reptileuv.com/megaray-sb-160-watt-self-ballasted-flood-uvb-lamp.php. Does anyone have any thoughts, i.e. is the wattage to low/high for a 40g tank and are they any good? also, i want to get a 100W heater for nighttime, is there any alternatives to the ceramic heaters and do they work well? I want something that emits no visible light for when he is sleeping. thanks-
