@Gargron@mastodon.social Ideed. I'm lucky that my University at least is somewhat competent and where replacing high pressure Hg vapor lamps with LEDs, they're actually opting for a low color temperature (~4000K-ish I'd say) and using fixtures that are mostly directed downwards.

@Gargron@mastodon.social Flicker rate… some of us see and/or perceive it, and it seems to trigger headaches. There are LEDs that don’t. Use them, especially where folks can’t easily opt out.

@Gargron@mastodon.social even worse than street lamps are the advertising signs glaring all night long. I hate them!

And in case you missed it, here's one other way sodium vapour lamps are cool. https://www.youtube.com/watch?v=UQuIVsNzqDk

@Gargron@mastodon.social you can’t really complain about leds being bad compared to sodium lamps for CRI reasons, low pressure sodium street lamps have a -44 CRI. Which actually does have benefits since it contributes to efficiency and reduced light pollution, but i didn’t even realize that CRI could go negative until i saw sodium lamp figures

@Gargron@mastodon.social I complained about high colour temperature LED streetlights to someone from the city of Calgary, citing all of the evidence that I could find about why they were a bad choice. Their response was that their wife liked the new streetlights. Now a bunch of them are also turning purple. We have literally painted our city in a bad light.

@Gargron@mastodon.social hahahaha, pick the right one? Just today I was marvelling at three consecutive street lights, each a different colour. They can’t even pick *the same* temperature.
