Bumping this as I am still looking for one. If anyone comes across one please PM me!

An grey Fisher Pierce would probably look decent and was available in the 70s.

There's some from the 90s for pretty cheap:

The oldest one I found was this from the early 80s but it's much more expensive...I personally wouldn't get it.

I've looked for those but I can seem to find one. I mainly going after those tall blue ones that they made around that time such as this one in this eBay listing: https://www.ebay.com/itm/167947718817

Well, Fisher Pierce made PCs in the 70s. I'd say go for either them or Area Lighting Research. My personal preference: Fisher Pierce. They often pop up for dirt cheap on eBay. I have one from 1979.

Was wondering if anyone has or knows of any era appropriate 1970s photocells. Preferably NOS to complement my mostly restored OV-25.

Such glow discharge passes very little current, so i think would not maintain the LC resonant circuit. So either there is something else outside the SRS circuit (like anothe luminaire) that keeps it going, or that discharge is actually a DC discharge from the capacitor, current limited by the state of the discharge itself and not by the ballast

I have tested SRS circuits in the past in an attempt to find out what exactly goes on. The voltage between the lamp electrodes during startup measures at around 270-280V. Whether this is due to resonance, or the fact that the voltage between the two coils is out of phase I don't know, but there is certainly a voltage boost.

If you disconnect the power to the circuit before the lamp has struck, the voltage across the lamp persists for around half a second, reducing slowly. This can be seen as a continuing glow discharge in the lamp that fades away.

Oh wow, I never knew about these! Extremely cool concept and fixture configurations! I can't fathom how expensive those would've been to build and install.

I find it interesting that Westinghouse made these. I was thinking something along the lines of Wide-Lite or Sterner Lighting.
