I do this with light bulbs too. The five year bulbs last about 8 - 10 months. LOL. I emailed my complaints to all the bulb companies asking why didn't the five year bulbs last at least a year. The responses were the bulbs were made to burn constantly. If turned off and on it shortens the life considerably. So the little money saved on power I was spending buying the expensive save power bulbs. I went back to regular bulbs for the lights I turn off and on.
