Ok, I have the same type of thing but the day light doesn't provide any heat. It's a Repti Glo 2.0. The UVB bulb doesn't provide any benefit, it was just what was available last time I picked up bulbs. So are you saying I should replace the repti glo bulb with one of those blue day bulbs instead? The daytime temps will increase and the nighttime temps will be somewhere around what they are now once the timer turns the day bulb off? Maybe increase this red bulb I have with a 75 watt hook up a dimmer? Did I follow things correctly?
