I have replaced all our Halogen lights in the Ceiling with LEDs.
The original Halogens get way too hot for me and they blow too often.
Love the LED's, run much cooler, use much less power, you do not get burned when you touch the light's lense, have not had a bulb failure in a year now.

Takes about 2 weeks to get them from China, free shipping, the LEDs have not caused any problems with any other electronics, warm light output.
Good communication from the company, I did have one that was damaged in shipping, they replaced without immediatly.
Note: I put the 25 Watt LED's in the ceiling and the 20 Watt LED's in the under cabinet, and the other smaller fixtures in the slides.
