I have a standard P45 45W single socket floodlight that I want to put a clamp-on wire cage to prevent theft of the bulb. I have three other bulbs with clamp-on protective cages but I can no longer find a source. Anyone know of one?

You may have to go to a wholesale electrical supply house instead of a home improvement store.
