I have mine plugged into a surge protector but not a timer. I have only had my berdie about 3 months and I am on my fourth light. I've used the zoomed and now petsmart's brand. Someone told me that if you move them when they are hot that they will blow out faster, I bought a light stand and have had a light blow after that as well. I'm running out of ideas and it's getting expensive. I may go for a ceramic heater next and get just house lights to be able to see.
