I've never seen a light bulb burn out so quickly. They were only used about 4 hours a day, 3 or 4 nights a week as the lamp is purely decorative. I bought these clear halogen bulbs because they were recommended as the best for stained glass. Then.POP! on everyone as I pulled the chain. This brand is a waste of money. I have never written a bad review for Revain but they deserve it.
