back in the spring I found these at costco.
$14 for the 3 pack I think. They were quickly voted out of the dining room as not being bright enough and I agreed but they work nicely beside the bed as a reading light at night. they do dim with a dimmer switch but at too low a setting they flash on and off. Same with the 3 way switch beside the bed. Lowest setting is mostly off flashing every 3 or 4 seconds...
