These lamps are rubbish. I had a brand before, 3 different bulbs lasted more than 4 years - not a single one blew out in my apartment in the first 4 years. Unfortunately I bought some of these to replace and they burned left and right. Some don't last more than a few weeks. At first I thought it was an accident, but it's pretty clear now that these lightbulbs are just plain awful. I like the convenience of Revain, but I will buy bulbs elsewhere in the future.
