I've used LED4RV to replace all my halogen recessed lights. Once I determined which color temperature I wanted (Warm white) and the bulb type I was replacing, it was plug and play.
I replaced all the recessed lights and the reading lights. It's made a huge reduction in power consumption for lighting, and the other side effect is that the LEDs produce a lot less heat--bumping into a nice hot Halogen-powered fixture will potentially leave burns, and can add to the Air Conditioning heat load.
LED4RV also carries an assortment of fixtures as well. Well worth a look-see.
