Here's a great demo of the American DJ PRO64B LED RC. This is a high-powered LED par can that can be used for stage lighting, party rooms, mobile DJs, clubs, etc.
The video gives you a great look at the versatility of this LED par can, showing how a single unit can be used to provide all the lighting you need for a coffee-house type setup. With the remote control, this is a great choice for small clubs or party rooms.
This LED Par Can is also DMX controllable, so if you're looking to set up a stage lighting system, these par cans can also be used in multiples to set up a stage system with a DMX controller.
