Has anyone seen GE Crimefighters that were not replaced during the conversion?

I have seen various fixtures that were intentionally missed during the LED conversion in my area. Some GE m-250r2s were spared amongst the almost complete LED street. Dunno if they work though.

I was in Chicago back in August, and did encounter a block or two of the M-400 Crimefighters.  I'm not sure if they were missed, but they hadn't been changed to LED for whatever reason.  I had come across single miss outs in the past, but I think they generally get caught quickly given that they'll day burn.  Previously the circuits used group photocells and they're being changed over to individual smart controls when LED are installed.  You can also find an odd Crimefighter here or there lighting up a lot or something that isn't part of the main street lighting system.

It seems like the 400w HPS Crimefighters are slowly disappearing from Chicago. The m400 Crimefighters probably would have worked excellent with probe start metal halide configurations as it is base up operation. The new L*Ds they are replacing the Crimefighters are some kind of GE Evolve. More like GE Devolve

The problem with probe start MH is the relativly short life coupled with rapid lumen depreciation . There were several MH streetlight applications around here , very few remain. .All of them SUCK for those exact reasons .

The Chicago "smart lighting" project that involved the replacement of HPS cobrahead and some but not all decorative HPS streetlights wrapped up at the end of 2021.  I don't remember exactly where the Crimefighters I saw were, though there's a stretch of HPS cobraheads on and around Lincoln Ave. that were still in service in 2022.  There's ongoing construction, so perhaps that delayed the LED installation.  Here at Ashland and Montrose and at Ashland & Byron are individual miss-outs.  As you can see they are lit due to them no longer being group controlled.

I'm not sure why these are lit during the day, but the new LED luminaires use individual PCs instead of a group control, so if any are missed they will be on all the time.  The city frequently disconnected the group controls before installing the LED lights, so it was not uncommon for the streetlights to be on for weeks prior to the change over.  That might be what's happening here, or there could be another explanation.

at Addison and Ashland to Southport and Irving park the whole area is more than 50% GE Cosmo White M-250A2 Crimefighters.

I find that group controls are much more effective than individual photocells. Much lower probably of dayburning, and if one does wind up going bad, you can quite easily identify the point of failure... just a thought.

My favorite lighting technologies at the moment are incandescent and mercury vapor, and my favorite Big 3 lighting brand of the late 20th century is GTE Sylvania.

About that Westinghouse Lifeguard disease, I think I've caught it. Thanks Eric!
