lot of unusual large old light bulbs, spotlight and specialty industrial vintage lightbulbs

Lot of five BIG vintage light bulbs as shown - these are all specialty bulbs, with different styles of elements and sockets. The filaments look good, but I have no way to test these and see if they work as I have nothing that they fit.

They're really great just as they are for that mad scientist or steampunk look, or maybe for Halloween decorations, I think!
