I have 4 digital 600s from HTG. I burn sunmasters in them. I have had one bad bulb which they instantly replaced. I started with one ballast, and never saw a reason to replace it.
Ive got two new ballest and ones never been fired,my shop says not to use those ballest with the eyes.The problem Ive got is my ballest came off the internet from Hydro wholesale

all i have to say is FUCK those digital ballast until they make them better. i have ballast that are older then me and all my ballast are over 5 years old . and when i put a new bulb in any of um they are danm near new again!
(now finding a good bulb is a lil different)
