A little over a year ago I installed a Hampton Bay 6-Light Black Under-Cabinet Xenon Puck Light Kit that I bought at Home Depot on sale.  BTW - I really like this set it comes with a tap dimmer pad for low, medium, high and off.  When I installed it one of the bulbs was bad & went out the first ime I turned on the lights.  I went back to Home Depot and bought a 2 pack of replacement bulbs for $7.97 + tax.
