sorry to change the subject but has anyone heard of or have one of those quantum 3 in one ballast? one e-ballast will run 250,450 and 600 watt lights in both mh or hps,its kind of iffy sounding on having a dimmer switch on a ballast and a built in fan too, I've really thinking bout upgrading on my lighting situation lately and was thinking of gettin one of those lumatek ballast but a 3 in one would be way cool what ya all think?
