We've replace the regular bulbs over 2 of the tables where I play with 100 watt equivalent spiral bulbs. These bulbs came from Wal Mart, and out of eleven bulbs used 4 have gone bad in less than 3 weeks. These things are made in China for GE. On the package in states that if the bulb doesn't last 5 years to send them back to GE. Nice! It would cost as much to ship them back as just buying more bulbs. And that's not including the gas and time to go to the post office. Just wondering if anyone else is having problems with this type of bulb not lasting?
