Chicago Residential Smart LED Lights

Chicago Residential Smart LED Lights

Click to view full size image

Here are a few recently installed LED luminaires in Chicago. I believe the Leotek on the left was an older non-smart light put in a couple years ago, in the short period after the switch from CMH to LED for new installations but before the smart lighting project. It's since been fitted with a networked PC module. Notice the difference now compared to before. This one may be malfunctioning, considering it's on during the daytime.

While there might be an occasional fault, most of the lights that are always on are non-LED or non-smart LED lanterns on a circuit that has already been switched over to continuous power. This is the case with the side-mounted coach lanterns on the right. Once crews rewire them, they'll be off during the day. There was even an article published informing residents of the reason why so many lights aren't shutting off as normal.

The lights on the right are entirely new cobraheads. Who is the manufacturer? Chicago had been primarily putting up GE Evolve as well as the occasional Leotek, but these look different, perhaps Philips?

Chicago is on track to finish complete the smart LED transition before the end of 2021.

the new led cobrahead streetlights photographed are Philips Lumec Roadfocus medium model (two rows of LED boards populated)...these can be each be controlled individually by a PC or networked...they may support intelligent dimming at programmable hours but I don't know for sure

I went to Chicago in March last year and they had lots of CMH streetlights. They aren't planning on replacing those with LED lights, are they?

Any machine is a smoke machine if you operate it wrong enough.

I've been to Chicago, in 2017, and saw 180 system watts LED replacing failed 250w HPS crimefithers on a residential road. I also saw many CMH heads replaced with LED (famed Lakeshore drive). If they are still matching those infamous Chicago lighting levels of the dated past, then Chicago will remain one of the brightest cities in N.A.!

Yes and no regarding the replacement of CMH. The project documentation states it does not include "previously installed white light fixtures", which would include CMH. However, from what I've observed, many of the CMH street lights are in fact being swapped out. This has included all of them on Lake Shore Drive and Western Ave., as well as those formerly in this neighborhood that have the new Philips LED lights. It's possible that some of the circuits that are entirely CMH rather than a mixture of CMH and HPS, will not be removed at this time, but we'll see. My impression was that those were to remain, but considering the number that have been changed out already, I'm not so sure.

Great, so those M400A2 FCO's in CMH that were on Lake Shore are gone now too? I was hoping to get good pictures of them sometime since they are so unusual.

Hmm, I don't think I came across any M400A2 FCO CMH luminires. But I quickly upped this composite showing the 310w CMH I saw (#4) on South Lake Shore Drive in August 2017.

The RIDOT uses the smart controls on the freeway lights here. Lots of issues with them dayburning, not syncing up (running dusk to dawn instead of running on the programmed schedule), or staying off at night. Once RIDOT gets the bugs straightened out they're supposed to start playing around with options, such as dimming the lights after a certain time, shutting off certain lights after a certain time, etc. At least that's what they said shortly after they changed all the lights in the summer of 2016. Three years later nothing fancy is being done with those ***very expensive*** controls. IMO they should have just stuck with the group-switched set ups they had used with HPS. Simplifies troubleshooting. If the pole has power and the fixture doesn't light, change the fixture. Now they have to go up in the truck and mess with the not-so-smart controls and see what the issue actually is. A massive headache when you have thousands of street lights on the freeway to maintain and a police detail and lane closures are needed. Waste of tax dollars IMO.

Also, why is the pole to the left installed sideways? Do they do that for a reason there or did they serious screw that up?

I've seen them installed too. They suck. The place that I've seen that uses them actually replaces these with standard PCs if they go bad. Guess they know the issues lol. Thankfully Caltrans doesn't use this crap. They still use group switched lights (probably because they don't have too many lights; usually at merges and exits). The long stretches of lights I've seen have a photocell at the top of a pole and a relay near the bottom of the pole.

I think I found a pic of a FCO M400A2 here, and CMH too.

Yes, I see somebody noticed that the one of the poles is sideways. It is positioned that way intentionally for the time being to make way for construction equipment.
