The new GE dimmable CFL bulb doesn't actually work. It glows nice and brightly, but doesn't dim when I turn the dimmer knob down. The packaging says it works with most dimmer switches. I wonder if I'll get the same result from the bulbs stephthegeek pointed to. I know I can return these to Wal-Mart; less obvious I'd be able to return the eBay ones. Might be worth a shot anyway.
