I have come across more than my fair share of pucks where the socket has been totally cooked and will not hold a lamp anymore. The look on the customers face is priceless when I tell them I cannot replace the puck because the installation does not meet code.(lamp cord through the walls) The lamps burn out rather quickly and they are installer unfreindly. They also do not produce a decent amount of light. There are far better choices available when it comes to undercabinet lighting.
