Im thinking about purchasing two 600 wtt HPS/MH switchable Dimmable Digital Ballasts.It comes in a package with a timer,hanging system,Winged hood(i know but i already have good hoods and will add one to this) Digital ballast and a MH and a HPS bulb for $199 each.Ive dealt with switchable MH/HPS Lights before,but never had a dimmable on.Has anyone got experience with these?.I also never really used a digital ballast,so whats the thoughts on these?Its a good deal for a 600 with all the extras..I bring up the price because im wondering how the $199 price compares to other dimmable digital switchable MH/HPS 600 Watt set ups?.Asking around before i purchase..Just wondering before i try out this new set up.I know,when i checked out the pix and it showed the ballast on a 1000 wtt one,you can dim it so its only a 500 wtt or a 750 wtt or a 1000 wtt one or it can bump up to a 1100 wtt.How does that work?How can it put out 1100 wtts in a 1000 wtt set up?Is it because of the digital ballast somehow?Thanks for any replys people.Peace
