There is a drive-in theater near me that still uses this type of projector... or they did a few years ago when I was last there.

carbon arc lights were commonly used in projetors and theater spotlights for many years. The carbon rods burn with a bright light and create smoke that has to be vented.

How long would the rods burn? It depended on the amperage used for the lamphouse, type of carbons used, etc. but you could setup for a 6,000 foot reel with an hour's running time. All of the installations here are for 2,000 foot reels so you would change over every 20 minutes. I handled carbon arc projection, and you would try to leave about 5% burning time available at the beginning so you could give the rods a chance to "burn in" before opening the douser-otherwise you might have flicker on the screen.
