Looks like I'd need a controller to use the dimming however. I don't think you can program those drivers. They connect to a controller. Also... since these things are a single color (12k or the bluer one) you'd have to mix them if you didn't want a really blue or a 12k look. By the time you spread these over a tank and start mixing I imagine you'd see the 12k/blue banding in the tank.
