How does one tell if a lamp is causing a problem or the ballast.
In particular, a parking lot HPS fixture is extinguishing for 2 mins and then relighting and staying lit for 30 min to 2 hrs and then extinguishing again and then relighting and so on.
I called a major ballast mfg. and the person who answered said "Put a new lamp in and if the problem remains...you need a new ballast" Ummmm gee thanks!
