just bought a 600w hps light hood and ballast...off craigslist... paid 150 for everything so no wonder as to why im having issues....go figure... but i put the hps bulb on first and it started up just fine and was working for about 10min then i notices a very slight flickering.. then the bulb shut off but was still glowing then turned back on about 10sec later.. then about 10min later it did the same thing...shut off then turned rate back on.. any idea as to why it doing this? ballast, bulb, or socket?
