[SML] 4 channel LED dimming. NOT RGBW

[Stuart Wheaton]

Looking to replace some obsolete LED dimming equipment.

The original system used 3 channels for RGB and a 4th channel for panel 
intensity.  so to light a panel, you would set the color and then how 
bright it was.

Looking to replace with a similar dimming system, since otherwise we 
will need to get the show re-programmed.

Does anyone have a source for LED dimming like this?

Thanks,
