If you have a very old thatrical spotlight I always recommend rewiring as a matter of course. Some of these old lamps have asbestos covered wire, unseen shorts, cracked insulation or any number of other potential fire hazards. Check out my other listings for some great vintage stuff. I'll be selling off lots of old film and theatre lights soon.
