      Old lights were atmospheric. They should buy LEDs that look like the old lights. Ya know, for the vibes. That’s a good use of taxpayer money /s

      I miss the yellow. I also found I could see better. Most of us live in a mix of rural/urban. I may drive for 5 minutes without a single street light. The yellow lights were more gentle of a transition. Now the transition makes driving in the dark so much harder. The bright white adjusts my eyes horribly both ways. Going from dark to that white hurts. Going from that white to dark, makes all objects not right in front of my headlights invisible

      A lot of LED lighting including parking lot and commercial lighting already has the optionality of changing both the intensity and colour of light. Most times it’s a couple of switches on the driver or lamp.
      Most installers would default to brightest setting and 5000k or 6000k daylight if available.
      But most you can set to 3500k, which is pleasant yellow orange and sometimes you can go down as low as 2700, which is like a warm incandescent.
      So anyway the point is that if you talk to the city or county or whatever about specific places where lighting could be adjusted- and assuming you get it approved, the change itself is probably just switching the settings.

    4. Curious if light pollution is measured any differently because of the change of light sources.

    5. I didn’t know Chicago changed to LEDs. I was out there 5 years ago and that hadn’t happened yet if I remember correctly. Thats sad I loved flying into Chicago and getting that lighting

    6. I don’t understand why we cant just use leds that emit light at lower temperatures. The short wavelength light is so bad for your eyes

      The LEDs create much more and much harsher contrast in my dense neighbourhood. I find it much harder to see pedestrians when driving, especially when it’s raining. The LEDs concentrate their brighter light much more than the sodium ones. The effect is very brightly-lit sections of street interspersed with totally dark ones.

    8. This is a beautiful example of government policy making a real energy change. Incandescent bulbs are basically no longer available. LED’s are often harsh, but man are they SO MUCH more efficient for our environment.

    9. Can someone explain to me like I’m five why LED lights produce crisper shadows and seem to have less diffusion?

      You don’t realize how shitty LEDs are until you go to a place that doesn’t have them. The sodium lamps are so much better to be around.

      The yellow looked better. 
      And with car headlights, the yellow was so much safer 😭

      There have been several instances where I’ve witnessed it personally, or I’ve seen the news where City and street lights were this really cool blue or purple color. It was fantastic. You can still see what you needed to see, it didn’t hurt my eyes, and it helped with seeing the sky at night.

      Then I find out that the LEDs were faulty and I’m wondering why it’s not done on purpose everywhere.

    13. This also seems to show less light being cast overall. I still see sodium lights here and there and they always seems to light up an area better than modern LEDs. A lot of the modern lights don’t seem to use good diffussion, but the contrast between light colors and dark colors seems to be much wider. Dark colors stay dark under LEDs, but sodium lights lit up everything.

    14. Being an electrician I’ve seen it first hand. I started out pulling a dedicated circuit to foyer chandeliers in the high end homes I worked in (could be 15+ 60w incandescent bulbs) now days you can run 140 led wafers/trims on a circuit if you really wanted to within reasonable distances.

      I was just thinking about this as I was out for a walk in my neighborhood under our newly installed LED lights lol

      How much of this is the switch to LED vs better cameras used in the latest photo?

      It still surprises me they went for bright white instead of the same orange in the UK too.

      The white is way worse for driving around in at night. Especially when it rains a lot and you just get bright white reflections across the roads.

      I miss the amber sodium lights. I know they were less efficient, but the harsh white LED street lighting that is prevalent now is absolutely retina-burning. Be neat if they could make the LED street lights a warmer amber hue like the old sodium lights. Easier on the eyes and night vision.

    19. Are there any figures concerning reduction in Electrical usage/costs with the switchover?
