We did that with a recent minor kitchen renovation. The LED fixtures and bulbs were expensive, but they give off great, natural-looking light, and should last a long time.
We have a small table lamp in our foyer that I put an LED light in over 5 years ago. The lamp has only been off when the power has gone off. LED is definitely the long term solution to lighting. Hopefully the prices start coming down.
the electrician when I got my new kitchen insisted that Halogen bulbs were the way to go for the high hats.
what a load of crap....they bring the temperature of the kitchen up to about 90°F in the dead of winter(forget about the summer) and when the lights were on I couldn’t read the numbers on the electric meter as the darn thing spins too fast....
I replaced them with compact florescent spot lights...
Really? I like LED's in my high-power flashlights, but I've never seen one with light I'd like to read by. OTOH, I haven't gone shopping in a long time. It'd be really cool if LEDs could give me light with some decent warmth to it.
