Might as well go crazy and do all of the utilities for a few different cities in my area.
Xcel Energy, my actual "local utility", has converted all of their streetlights to GE Evolve 250w fixtures as of 2016.
My home city of St. Cloud, Minnesota, has the distinction of being both one of the first and at this point by far the largest Minnesota city to utilize 100% LED public lighting. St. Cloud also uses GE Evolve fixtures for all cobraheads, but in a number of wattages.This conversion was done concurrently with the Xcel conversion in 2015. All decorative lighting (basically anything other than a cobrahead) was upgraded on a case-by-case basis the following year, choosing fixtures that suited the respective decorative pole. Additionally, the former "shoebox" fixtures in the downtown area were replaced by these unknown (and ugly, in my opinion) LED fixtures: https://goo.gl/maps/BVWNharKeRxrT3dE7
Other area cities:
Sartell, MN: The majority of cobraheads in Sartell as far as I know are owned by Xcel Energy, and are also GE Evolve fixtures. A small number of what I believe to be city-owned cobrahead fixtures are all AEL Autobahn LED fixtures. All other public lighting is city-owned and decorative, with 150w and 250w LED bulbs retrofitted into older existing fixtures. The utility conversion occurred in 2015, the citywide conversion just occurred in 2018.

Sauk Rapids, MN: Again, all utility lighting is 100% converted to LED with the GE Evolve fixtures. Like Sartell, nearly all city-owned lighting is decorative. Sauk Rapids has publicly announced plans to convert all remaining fixtures to LED next year, but as of now much of the decorative lighting still remains HPS. However, the city has used exclusively LED fixtures for new installations and spot-replacements for a number of years.

https://goo.gl/maps/g5LY6XBiBzCRfPrE9 -This Model 25 is one of the few city-maintained cobrahead streetlights, and is also set to be replaced next year.
Waite Park, MN: The only city in my area that has no public plans to mass convert its lighting to LED. Again, the utility lighting is all converted but city-maintained lighting is HPS. However, new installations have been LED for about four years now (again, mostly decorative fixtures that I can't identify). Spot-replacements have been exclusively LED for about a year or so now; mostly with AEL Autobahn fixtures. Prior to that GE M250FCO fixtures were used in spot-replacements.
Waite Park Lighting:https://goo.gl/maps/SsgqD4caZjKUpX7S8 -St. Cloud/Waite Park city line. Very interesting contrast at night.
https://goo.gl/maps/81XeBW9Ux1u8bmZK9 -C. 2017 decorative lighting in Waite Park. That design is used across the city and as far as I know is just a HPS fixture with an LED bulb in it.
With a few exceptions, my area is almost entirely LED and has been for several years. As a side note, I'd love help in identifying the decorative fixtures as I really know nothing about any of them.
