Lit with the new ballast, works great! I wired it right which is good. Nice for the gold NEMA tag to match the wattage now, now I have a spare 250 watt HPS ballast. xD
NICE! It looks great! I have a spare 250W HPS ballast too, 120V single tap. It goes in a 1980s ITT model 13 which I don't own, but i own the ballast. I also have a 400W Westinghouse CWI ballast that's 120-277V and MASSIVE! It's dead-silent even though it's huge. I've noticed Westinghouse HID ballasts are typically very quiet. The Westie ballast serves as a weight for the base of my street light pole since otherwise it could become top-heavy and tip.
