Re: Lamp killing circuit breakers?



Good reply Steve! I'll further add that some of the better-stocked hardware
stores carry a line of lamp repair kits and parts, including adapters and so
forth. It would be good if Michael made a complete job of it, including
rewiring the old lamp from the plug to the socket.
