-We have two types of RGB pixels, 12mm and 20mm. They have the same controller chip and use the same power but the LED and shape differs.+We have **three** ​types of RGB pixels, 12mm round, ​20mm round and 36mm square. They have the same controller chip and use the same power but the LED type, number ​and shape differs.

 +The 36mm square pixels are the biggest and brightest. They have 4 LEDs total and come in a flat metal square '​plate'​ that is flooded with epoxy. They require 12VDC power and can draw up to 120mA per pixel (there are two sets of two RGB LEDs connected in parallel for two 60mA draw from 12VDC).
