The Chauvet Cosmos Rotating Ball Effect LED Light is powered by four 3W LEDs which offer adjustable speeds and constant rotation with coverage of 360°. That’s literally everywhere! Rotation speed can be adjusted from 0 – 100% and the LEDs will change in response to the beat of the music. There won’t be an inch of your club or dance floor that isn’t saturated with brilliant, ever-changing color. The only thing that can top this light is more of them. Up to 24 Cosmos LEDs can be power linked to save on cabling and extension cords. That’s a lot of light! The Cosmos is multi-voltage so you can run it anywhere that has electricity. And you can run it all night without shutting down for a duty cycle; run it until everyone leaves or you run out of energy because the Cosmos won’t.
