Sorry for the double post... Here is what I got:

A single Reefkeeper ALC has 2 - channels for 2 independent dimming controls. A Neptune Systems Apex Variable Speed Dimming Module has 4 - Channels.
This unit can accept any 0-10V analog signal, and create a proportional PWM signal output, this can be for virtually any use, not limited to aquarium controllers!
Your Aquarium Controller Interface now comes with the optional ReefKeeper plug that connects directly to your ALC.
