The kitchen in the condo that I rent uses these:
I think that they are called MR16's; 50 watts.
They burn out way too quickly--if a bulb lasts 6 months, it is a near miracle.
They also seem to be much more difficult to find (in bulk, at a discount, whatever) than the seemingly more common (and cheaper) GU10 bulbs.
The developer (and/or their designer) who decided to use and install these light fixtures in the kitchen should be shot.
