Icecap 660-009 ballast, can I ramp-up and then ramp down, the lighting some how..? I use a few of these on various tanks, as I just Love them. I am running UVI T-12's two 72 inch bulbs per ballast . And then secondly, how about dimming them there is a plug in on one end just for that! But I can't find any info at all on this? These where the main stay for years... Love them still... I thought I had a problem with two of them last week.. nope just a loose wire lol. Just an old reefer here, maybe I am just stuck in my old ways..? lol. Please any info would be appreciated greatly ...

According to coralvues website, with T12s it should be fully dimmable

IceCap 660 VHO-High Output Electronic Ballast

The IceCap 660 VHO ballast reliable yet silent operation & will drive all VHO-very high output florescent lamps, in various combinations up to 4 lamps up to 440 Watts. 3 year warranty.

Not certain what method it uses for dimming, although if it is 2 wires it may be 0-10V. Dimming method will determine if/how to ramp up and down
