What are LED fog machines and what are they used for?

LED fog machines combine a standard fog or haze machine with a ring of high-powered LEDs around the output nozzle. The LEDs illuminate the fog as it exits the machine, creating a towering column of colored vapor. This creates a pyrotechnic-like visual effect without any open flame, making it a safe alternative for venues that prohibit pyro.

The effect can simulate fire, geysers, or dramatic colored plumes. Some advanced LED fog machines, like the CITC Maniac, add moving light functionality so the colored fog output can pan and tilt. The Chauvet Vesuvio II RGBA is a popular rental option that combines fog output with RGBA LED color mixing.
