Just finished putting LED disks in the under-cabinet puck light holders. Found that Beaver used 2 different puck light sockets. The ones in the ceiling have a "wrinkled" metal finish in the reflector and the under-cabinet units have a smooth finish reflector. The LEDs I spec'ed earlier in this thread fit the under cabinet sockets fine. However, they DO NOT FIT the ceiling sockets. Apparently the spacing on the LED chips changed, resulting in an increased diameter when compared to the previous units I ordered. Love that precise Chinese manufacturing machine....
