Chicago M-250R1 in my Room Decided to take down the OVC and put up my Chicago M-250R1 with the embossed "C" on the door. This guy is NOS but the dumb@$$ seller broke one of the hinges (the hinges were not broken in the listing pictures). The door stays shut fine with one hinge. The only time the missing hinge is an issue is when the door is being opened (it'll drop free out of the hinge cradle) so you need one hand to hold the back of the door against the top housing. The tape is just a precautionary measure, it isn't essential to keep the door up. The tape also allows the door to be opened with one hand, without worrying about the back end dropping out. On this fixture, the ballast is mounted to the door, so unfortunately that adds to the weight on the door. Keywords: American_Streetlights

I have this running right now, wired for the 90W tap. It's running a nice 100W GE lamp (i think from the early 90s) that starts off blueish-white. Very Happy As the lamp ages, the bluish-white color should be more lengthy during the warm-up phase.

Cool find, whats the year?

Thanks Dave. Smile I bought this off ebay a little over a year ago. It's from May 1981 and has an embossed Chicago "C" in place of a NEMA tag. Joe Maurath Jr told me the ballast-on-door concept blew him away. It's essentially a single door Powr/Door fixture.

BTW, Joe told me to ask you for more infor garding a rare 70/90W HPS lamp that GE made back in the 80s. He showed me onw but has has no idea what it would have been used for. He said if anyone knew, you would be the person to ask. This fixture's nameplate says under ANSI code that it takes S54 lamps but under LAMP WATTS it says 70/90. And the wiring of this is weird. To change wattages, you need to change a connection on the ballast core and on the igniter, which is odd because 30-150W lamps all should use the same igniter (except for 100V 150W lamps).

An oddball fixture, that's for sure. And certainly a welcomed addition to my collection, since I love HPS lights from the 70s to the mid-90s.

Is the hinge on the door its self broken? I may have a NOS door with the C on it.

Yep the hinge is broken on the door itself. A regular M-250R1 door does fit this but the ballast is mounted to the door on this unit and a regular R1 door has no screw holes unfortunately. If you have an extra one with the C, it probably does have the mounting provisions though. Definitely interested if you don't need it (and have it). Won't need any of the guts since I can transfer these over to the new door.

I'll look, I know I had the same fixture at one time but the upper housing was damaged and I think I saved the door. Once I find out, I'll let you know.

Cool, thanks! Too bad on the top housing being damaged. Wouldn't a standard top housing work as a replacement though? Mine has a standard top housing with all the usual screw holes and indentations for a top-mounted ballast. BTW, did you get my email? I sent it from my phone but it didn't appear in my "sent" folder.
