I do. I am now running Lumatek 400 watt dimmables. They dim manually via a knob and its a set it and forget it kind of thing. You can take a 400 watt bulb and run it at 250 watts. You can also overdrive a bulb which isn't suggested. They will also support HQI bulbs at the correct voltage.

I had the "dimmable" coralvue and quite frankly they were not impressive and had a number of significant flaws IMO. However, I now run the Lumatek/Galaxy "adjustable" ballasts (I have the 150, 175, 250, 250HQI version) and it's by far the best ballast I've owned.
