They are warm, recessed, low voltage LED puck lights. They can be purchased at just about any electrical/lighting supply company. They are wonderful, because they give off pretty much no heat, require very little electricity, don't require much depth, and give off a warm, attractive light. If you have problems finding a source...fire me off an e-mail, and I'll help you directly. (But do have a good look first...I'm very helpful, but very busy). :-)
