No bulbs ~ Carbon arc. 78 DC Volts @ 150 amps arcs between open-air (+) and (-) electrodes producing 800,000,000 candlepower from a 60" Rhodium plated parabolic reflector. GE and Sperry made these light/generator sets in the early 40's for WWII anti-aircraft use. Beam length is 6 miles. Can be seen 30 miles away on land, and from outer space.
You are thinking xenon lamps as used in modern searchlights, cinema projectors, etc. The IMAX projector uses a 15,000 watt short arc xenon bulb. This WWII era searhlight uses two carbon rods for the arc.
My Mag-Lite is still brighter. xD

This technology only popped up on shelves ten years ago. I came to this link researching a ufo story from Los Angeles 1942! "Blue search lights".

I read that these have 800 million candle power.
They don't even have a bulb, they have two graphite electrodes and arc electricity between them to produce light.

Actually, there is no bulb which could explode xD
Nevertheless very impressive!

Wow 15,000 watts! Handling those carbon lamps...dangerous since they are in high pressure and the bulb can explode if not handled carefully!
