"Spotlights like this one used to be an icon of Hollywood. A collector will probably give you $400 for this one."
- Fact 1: The use of spotlights at film premieres dates back almost to the birth of the film industry; it is still used in industry logos such as 20th Century Fox's.
- Fact 2: Spotlights typically use arc lighting, in which a plasma arc between two metal rods creates heat and light. Arc lights generate excessive UV light, and are generally only used in outdoor lights.
- Fact 3: The carbon-arc light used on spotlights was first demonstrated in 1802, but the technology was not commercially successful until electricity was made widely available in the late 19th century.
- Fact 4: The most powerful spotlight on Earth is located at the top of the Luxor pyramid in Las Vegas. Its 40-billion-candela beam is almost twice the brightness of the surface of the sun.
- Fact 5: Once powerful military tools, spotlights are now used mainly for advertising and events.
