New setup huh? Awesome!!!!

Yup. Four through bolts through 4X4 posts and a 200 lb. guy wire hanging from the rafter.

Wow! Out of interest, how much does the refractor ans door together weigh? is it true that these beasts really weigh up to 100 pounds? Shocked

I have both a merc and HPS M1000. The Merc weighs around 60-70 pounds, the HPS aroung 80

Wow! Does the HPS one have a "mag-reg" ballast like a lot of the early HPS ballasts? I have an 80s 400W HPS Westinghouse ballast and it's huge and quite the paperweight, probably about 20 pounds by itself.

It came out of a 90s Hubbell floodlight and it is gargantuan.

ahh was the original ballast not 120V? Interesting... I figured by the 80s HPS ballasts had shrunken down somewhat.

The original ballast was rated for 480volts, but that was when the fixture was first manufactured. It was refitted with a 400 watt ballast and spent many years lighting a parking lot at the local B-Kwik. In 2008, two of these, along with two Pemco 400 watters, were replaced and I got all four of them. As to the HPS, light, it was originally a Merc with a 120V ballast, but the ballast failed. Now here's where it gets complicated. I bought a new 1000 watt MV ballast on the 'bay and put it in the step door. then when I got this one, I switched the MV ballast over to this and sunk the HPS ballast in the step door.

ahh yeah for such a high wattage 480V makes sense because even with a 100A breaker, at 120V you could only have twelve lights. It wouldn't make too much sense lol. So the step door light was originally a merc as well?
