| Let you know the 600 w HPS is common item here in larger luminarie useage. I do run into the 600 watter from time to time. Now senice the OP is from Canada there is a issue with the ballast and socket set up due the Canada Electrical Code is little stricter on this part than NEC { USA } is due the the way the ballast connected and the 208 and 240 volts ballast have some safety issue with connection unless it have CWA ballast then it should be ok. The green wire is a bonding it must be used on the ballast for safety reason. I will get ahold of one of my Canadain freind to confirmed about this matter.
