Here's a quick look at the American DJ Starball LED DMX Special Effects Light. This light is great for clubs, mobile DJs, and party rooms.
The Starball LED DMX essentially takes the place of a mirror ball. As you can see from the video, it throws off beams of white light, much like a disco ball. But it makes life easier -- it's super-convenient not having to deal with a separate motor and pin spots, and this fixture is all-LED, so it can run all night and emits almost no heat. At only 4 pounds, it's also easy to move from place to place as needed.
The video gives you a look at the effect produced by this handy fixture, as well as an overview of its operational specs. It can be controlled via DMX controller (2 channels - dim/strobe and rotation speed/direction), or set to master slave or audio response.
All in all, a handy effects light that is easier to work with than a mirror ball.
