With all due respect, the puck lights get more than a little warm, and it is reason to be concerned. I have seen the wood on kitchen cabinets burned when these lights have been removed, and that is a potential fire hazard. LED's are cool burning and long life, and are the way to go today. Properly installed, they are also less expensive than puck lights.Xenon is just another form of Halogen. The xenon puck lights get a little warm, but nothing to be concerned about. The bulbs will last a little over a year with every day use.
Dunno much about LED's, other than they last a lot longer.

That could very well be the case, but I have also found one instance where someone replaced the halogen lamps with ones of a higher wattage. They actually smelled a burning odor and called me instead of the fire department...this was their second error of the day, duh! More wattage=more heat, and the higher heat exceeds the insulation rating of the device and sometimes its internal wire insulation, potentially causing a fire. The same is true of lighting fixtures attached to ceilings and walls. Each has a maximum wattage clearly labeled on the device, but users can increase the wattage with a different lamp, as the screw-in lamp base can be the same size from 15w to 150w. LED's, on the other hand, emit very minimal heat, and since they are part of a printed circuit, there are no user changeable parts. LED's also use much less power, thus having a shorter payback period (ROI). IF someone is determined to use halogen puck-style lighting, I hope they at least buy ONLY fixtures with the UL label, and not increase the wattage of the lamp in the fixture.JEV, I'll always defer to your expertise, here. The ones I've had for over 3 years are only warm to the touch. Perhaps the heat problems are brand specific?
LEDs. You can now buy dimmable LED's. I bought mine from an online place. The strips is just that - a paper-thin strip with LEDs built in. No fixture to speak of. Comes with a control and you can make them bright for work, or dim for effect.
