Here is a recent story with some updates and more information. LeDuff report: Detroit's lighting system problems are shocking I'm curious as to what the upgrades will entail.  Will any of the old ornamental lampposts and teardrops remain?  I'd be nice to see them restored, but more likely they'll be ripped out in favor of HPS cobraheads on wooden poles with overhead wiring.  That seems like the most economical option.  Supposedly they plan to be finished in three years, but I'll believe it when I see it.

I guess they will work only on basic functionality (to get the streets illuminated at least somehow), because there simply won't be money left for anything fancy. And the cheapest are HPS on wooden poles, with overhead wiring...

The Public Lighting Authority began installation of new lights in pilot areas back in November.  They started off with HPS GE M250s as shown in the video, but are planning to proceed with LEDs from here on out.

It seems, the LED is gaining over on the estimated cost ground, that is the strongest argument, mainly for these days and I would guess near future as well. The question is, whether the "reliability" of the large part of today's production won't make them more expensive in the long run...

I predict after 1-2 winter/cold seasons they will see some big problems.

Detroit does need streetlights with photocells on them. I am guessing that installing  HPS streetlights are cheeper than installing  Metal Halide lights? I also saw that some of the electrical poles themselves could be replaced too. I also do agree with the city installing LED lights too. I mean Detroit does need to use Energy Efficient products if Detroit's Electric Company remains on a budget in running their power supply. My opinion is that I think First Energy or AEP should've took over Detroit's Power Company

6500K Color Temperature Kelvin lighting works for me. I use 6500K CFL in all my incandescent light fixtures. I use 6500K Flurescent bulbs in my flurescent fixtures. I hope prices get better and hope I find 6500K LED lighting in the future. I love energy efficient and Energy Star products. Way to go!

Given the crappy life expectancy of MH over HPS, it is wise of them to be using HPS.  Less truck rolls to replace burned out MH bulbs and right now, HPS bulbs and equipment are cheaper.  Sure they may not be as energy efficient, but just think about the energy used to have to do all that maintenance on the MH fixtures that will fail when the HPS stuff is still going strong.

Strange. I thought the Metal Halide lights have been available since around the early 1980s although most of them were mostly used in freeways besides the HPS that they also have been using too. Maybe that might've been been why some of the freeways changes the Metal Halide light to HPS lights in the late 1980s or so maybe? Nowadays, it seems like Metal Halide is now being used in more areas in the 1990s and 2000s  I guess RyanF40T12 has seen more experiences with them?

My experience has been limited to 175 Watt and under MH.  And the rated life for them is under 14,000 hours.  The brighter ones used in street lighting seem to last longer but not anywhere near as long as HPS.  Also, keep in mind that many of the Mercury Vapor lamps of the 80s and 90s were improved and used better things to give it a more crisp white output instead of the greenish look.
