I did see some PWM adaptor boards. I didnt know what I was seeing when I came acrossed them. These boards take the place of the pot to provide a PWM input for electronic control. very cool.

Marty, take a look at this. I don't think the manufacturers of the China LEDs invested extra $ in more drivers than absolutely necessary which is why we see most units have 2 channels and only 2 drivers. I think they just wired the LED chips in parallel, which it sounds to me doesn't over run the driver. Sounds like the Meanwell ELN 60-48P would work? They sell them at RapidLED.
