Brian - Great info!
Is it possible to overdo the green water?
I'll check with our lighting guy's at work and see what they have in LED. I know they install a lot of them.
A salesman brought in a demo unit that has a 120Vac control module and you can control the intensity with a 0-10V analog signal, or a dimmer switch, but with analog you don't get that "click on" effect.
