I have the whites on a driver and the blues on a driver... so I can adjust them individually to what I like. The light is comparable to my t-5s with the exception of the blue LEDs.. They are WAY more blue than the t-5s ever were..
The Pots did not come with the drivers. I purchased them at Fry's. The drivers I purchased have two output wires to connect a dimmer of sorts. That is where I connected the Pot on each driver.
