List of Pixels
Intro
Here is a short list of what is out there when it comes to pixels. The list would be huge if all of them were here or where you can get them. These are the main ones used or the main protocols used. Alot of the different pixels manufactures use the same IC chip (Ie - WS2801, 6801, 3005). So that is the real important part when trying to choose the right pixel for your controller.
GECE Lights
Sold in stores as a stand alone string that can be used with E680/681 controllers to allow full control of lights. Once connected to a controller you can control individual lights and increase the flexibility of what you can do with them.
