We ordered these in January to replace our under cabinet lights. All the lightbulbs we had were there before we moved into this house almost 2 years ago. About 2 weeks ago, three of the four lamps we bought had already burned out. So they lived about 2 months. They only turn on at night to give my kids some light as they walk through the kitchen to the bathroom. It seems pretty ridiculous that they only lasted 2 months and didn't work more than 8 hours a day. They are said to last around 20,000, but they lasted less than 500 hours. Will definitely buy another brand next time.
