At the CT Folk Fest in September, I picked up (for $10) a "green lighting box" that contained a small desk lamp, six CFL lamps, a night light, and an LED lamp. The total was a bargain, but I was most interested in the LED lamp. I installed it in my bedside table lamp where its fast turn-on and brighter light was a welcome improvement over CFL.
PERFECT opportunity to try out LED lamps - I picked up three "12W= 60W equivalent" bulbs that have worked out perfectly. The bulbs are dimmable (standard dimmer), they seem brighter than the incandescent bulbs (more light directed down and out, less towards the base), and the fixtures / globes now run cool to the touch. I feel much better about leaving these lights on - making the kitchen warmer and more welcoming.
So - LED bulbs for the win! I'm not going to replace my CFL's quickly or globally, but the LED technology seems like a winner from where I sit!
