I am trying to use one hot side of a irrigation system generator, with the other wire of the socket tied to ground. The bulb lighted for about 5 minutes....seemed great. Then it blew out the screw-in base. Should I switch leads on the socket? Or use a limiting fuse? Maybe the hot side should be on the point of the bulb, huh? The bulbs are $9 apiece and I don't want to burn out another one.
