Ballast and starter to the 70 watt hps 120 power door , This thing is light as a feather. The ballast is so quiet if it weren't for the lamp you wouldn't know it was on.
Nice! NOS in the box? Yeah my Cooper OVC is 50W HPS and it's by far my least-heavy light. And yet it's one of the few of my lights that has a 4-bolt slipfitter lol. My only other light that has a 4-bolt fitter is my M-400A2. also, interesting how this uses the pre-mid-80s black plugs instead of having the plug connect to the base of the igniter.
Yep, NOS in the original box. I was also surprised to see this configuration instead of direct plug to the ignitor. Just about all my large lights and some of the smaller ones are four bolt except for my GE M-400A3's and M-250's. I honestly think the four bolt ones are unnecessary.
Yeah 2-bolt is sufficient and more efficient (less material and also faster to install) though I kinda like 4-bolt fitters for some reason. My M-400 split door and OV-25 have two bolt fitters.
Funny thing is, in the 80s the M-250R2 (and probably M-250A2) had 4-bolt fitters and the M-400R2 and M-400A2 had the 2-bolt rocker fitter. then in the 90s The M-250R2 (and probably A2 as well) became 2-bolt and the M-400R2 and M-400A2 became 4-bolt.
