I see a little bit of water has found its way in.

Unfortunately, these luminaires are built so cheap that it's a shame that they were designed and built by Westinghouse. No wonder Cooper did away with it. The only good parts were the refractor and the reflector box which were a hold over from gen 3. I had one of these...if they get water in them and corrode (like mine did), they're almost not worth bothering with, and let's not get started on the open slip fitter which turns into a rust bucket.

Your mission - should you choose to accept it - is to save unique and rare HID lighting before it's all scrapped.

Yeah really crude lights. Westinghouse ballasts from that era are junk too. One of the nice things about these lights though is that the ballast is just held in with a bracket across two long threaded rods, so really you can fit any ballast inside. A feature that was carried over to the OVS and OVM but for some reason Cooper did away with it when they rolled out the OVC in 1989 and all their current models that rolled out in the 90s.

I have two boxy OV-15s. One was an eBay find with a 480V ballast. Converted it to 85W QL (induction) with a kit I had and added a PC socket. I also replaced the rusty slipfitter threaded rods and nuts with stainless replacements. The second 4th gen is a 100W MV 120V. The original ballast was toast so I stuck in a 240V 1960s GE one from a M-250R. I now have a more proper replacement, an early 2000s 120V HX one out of an OVZ. The Cooper ballasts really haven't changed much from the late 70s/early 80s Westinghouse design.

I also heard that the slippfitter mount on these fixtures gets rusted, due to being exposed in the elements. Are they replaceable? I was thinking of saving one of these, once they do the change out to LED.

Save the Cooper OVWs!! Don't them down by crap LED fixtures!!!

Yeah the threaded rods for the slipfitter do rust. I replaced the bolts on one that I have.

Hmm, ok. Whats the diameter of the threaded rods? I might save one of these and restoring it like new. And maybe put in a new MV or HPS ballast in it.

On mine they are 3/8". I was going to try replacing them but they seem to be stuck so I don't think that's happening.

Yes they use 9/16 nuts which is 3/8 threads. I heated mine with a propane torch and used vise grips to remove the old rods. Works fine as aluminum expands more than steel so it loosens up.
