I've been in the industry for over a decade and I find it fascinating how much lighting has changed in that time. When LEDs were first available, they were $60+ per bulb. Now you can get multipacks for under $10. Also, CFL bulbs were almost universally hated by everyone (and for good reason) now we no longer sell them. We strictly sell LEDs for regular lighting and we still sell incandescent specialty bulbs. Also, when LEDs first arrived there was a lot of distain for them, especially by the elderly. They wanted their energy wasting incandescent bulbs dammit! It seems the majority of them have come around because they've learned that LEDs are better.
Also it became a political issue as all things should be somehow
I specifically remember trump saying something about bringing back yellow light 😮💨
Yellow street lights are actually very good.
For sure, but if an entire city switches over to LED, that is a lot of electricity saved. Imagine the impact an entire country would have.
No. High pressure sodium lights produce more light for the same wattage. HPS produces 80-140 lumens per watt, LED produces 30-90 (https://ledlightinginfo.com/why-are-street-lights-yellow-and-not-white). They also tend to run slightly warmer which means they are less likely to be covered by snow. That's why Europe is still using them everywhere.
I've heard the LEDs offer much less light pollution, but perhaps that is not unique to technology difference and just the difference in lumens?
Also, I'm surprised there aren't equal lumen led lights.
