Chase controllers create effects across the channels of the controller and allow you to do all sorts of creative things with lighting. For example, a 4 channel chase controller will turn channel 1 on and then off when channel 2 comes on, channel off when channel 3 comes on, channel 3 off when channel 4 comes on, and then the sequence repeats. The same is true of 2 and 3 channel chase controllers. The speed of the chase between channels is controlled by a dial on the front of the controller. We carry basic multi-channel single function controllers, multichannel multifunction controllers and higher power, more flexible programmable Christmas light chase controllers for all of your project needs.
