    2811 pixels are 8-bit, hence the 256 possible levels per colour.

    2811 is a 8 bit per colour chip. 256 steps per colour so 256 x 256 x 256 for a possible 16777216 colours. The 3001 and 3005 are 12 bit.
    DMX and E1.31 communicate at 8 bit so the main advantage to using higher bit levels is the ability to adjust dimming curves and gain

    Thanks for clarifying this for me! Out of curiosity, which protocol would be 12 bit then?
    Also, has anyone used the RGB mentioned in my first post? Any good?
    Thanks!

    Usually the 12-bit pixels are used with controllers that convert the 8-bit data to 12-bit for gamma correction purposes. I'm not aware of any controllers that accept other than 8-bit data. All of the current software packages work in 8-bit anyway.
