I'm very happy with the LED bulbs I placed in kitchen and bathroom cans...haven't burned out in 1.5 years and the lights in kitchen are on 16 hours a day. Just replaced my exterior stair lights and waiting to see performance on these newer ones.

We put LED lights in about 85% of the kitchens we do now. They are the real deal. Energy efficient, produce little or no heat, easy to hide in under cabinet applications, last forever and the cost are coming down rapidly. They do require some knowledge to make sure you use a spot or a flood dependingon what you are trying to put light on. We use 12 volt, 24 volt and 300 mili-amp depending on the brightness you desire. They can also be installed in many places without needing an electrician, since they are outside walls and are still considered low voltage application. Hope this helps!

Thank you for your reply. Will any light fixture burn a LED bulb? or do they have to say LED fixture on them someplace?

You cannot put an LED in a halogen fixture. Right now. But the market is growing by leaps and bounds so who knows in the future.

This dilemma has caused me to research LEDs they seem to not be advisable in very hot or very cold climates. I live in a moderate climate but it is interesting. It also appears that they can be used in any fixture if the bulb includes a power converter or at least a current-limiting resistor. Still learning.

When you are talking about bulbs burning out, a lot of fixtures are not so appropriate for cfl or led. They keep advertising that they don't give off the kind of heat that an incandescent bulb does, but they fail to mention that they can't handle the heat either. Neither cfl or led should be put in an enclosed fixture if you don't want them to burn out. New light fixtures are starting to label for both max incandescent and max cfl bulb sizes. In general, if a fixture says max 60 watt incandescent, it will say max 19 watt cfl. A 13 watt cfl is said to be the equivalent of a 60 watt incandescent and a 19 watt cfl is equivalent to a 75 watt incandescent. If the max watt for incandescent were 75 watts, then the max cfl would be 23 watts or 100 watt incandescent equivalent. Otherwise, they burn out their own ballast. The same thing applies to led in general. Those cooling fins on the bulb are not just for looks, and in an enclosed fixture, they get no air circulation.

What I heard about CFL's was that they only last a long time in rooms where they are left on, so where you switch on and off every time you use the room (eg bathroom) they burn out quicker. Also dimmer switches are an issue.

Here is a breakdown of the best energy saving options out there it might be of some help to you.
