Ok. I kinda figured. I know someone who just got a bearded dragon for her son. And they have a coil bulb. I used a tube when I had my dragon. But I remember he would just stare up at it sometimes. I will tell her to replace it. Thank you.
The main problem is that a coil bulb was designed to work in a hood where the bulb runs horizontal with the length of the fixture and NOT as a bulb to use in a hood that makes the bulb point downward toward the reptile....so, there is that.
