The FCO reflector design is also 80s. The very first M250R1 FCOs in the late 70s had smooth reflectors.

I didn't see many FCOs in MD until roughly 1995......I know a small group of GE M-400A1 FCOs in MD...which I remember seeing way as far back as 1986....but haven't confermed what reflector it has....I always saw it from eye level while traveling past it on a raised road and the fixture was on the lower level...

Hey Jace,the date of the fixture is May 1981.

Nice

Darren, can you post a picture of your M-250R2 and this door side-by-side? Are the doors interchangeable?

I would say the doors look interchangeable, and Darren sure is getting alot of picture requests lately

As far as I know, they aren't interchangeble.....the latch is slightly different and the front part the rim is smaller.....meaning there's no pointy front, I believe the front area space was elminated on the newer R2

Okay Jace I was just (for some reason) looking at the hinges (which do look interchangeable) So just ignore me saying that

I like how the gasket is on the lense and not the reflector! Interesting design!

Yeah, different.

I never knew they made these in 250 watt HPS.

We have a bunch of these on the Baltimore beltway that the State Highway maintains. They are the drop lense though not FCO

Yes and the Capital beltway has a lot of L-150s along with some of those GEs

Yeah, in the '77 catalog i have, it doesn't have 250w HPS listed, though 250w MV is

I've seen HPS wattages as high as 150 watts.

yep, that's the highest wattage of HPS listed for this and the M-250A in the '77 catalog.

What is the voltage of this ballast? The insides of this look VERY similar to the insides of my M-250 R1 FCO. It also looks like this fixture has a reactor one-coil ballast, like in mine. Mine is wired for 240 volts, and can only be used for 240 volts as there are no single-coil 250w HPS reactor ballasts for 120 volts.

This is also a 240V ballast.

Is the socket on this Adjustable? Mine doesn't seem to be.. The socket is just directly screwed onto the reflector with two screws, no brackets or anything.

Wattages under 200 probably had an adjustable socket. See how close the 250w lamp is to the edge of the reflector? There's really no room to adjust it...
