Review on Efficient Industrial Electrical: Compact Fluorescent Spiral with Equivalent Lumens by Matt Bell

When I ordered these bulbs, 1 died immediately after unpacking. I sent them back and got a replacement. 2 bulbs that I use every day for a few hours and they were fine. I have 2 more in the lamp that I use a few times a week and they have been fine for about 3 months now. I have 2 other table lamps that run 2-3 hours every week and one of them died. The lamp must be operated for more than 20 hours total operating time. I also don't see any warranty or support information.
