(what is with those streetlights tho)

Defective LEDs with massively reduced service lives made it out of the factory and into streetlights around the world. If you ever see a purple street light, a failing LED module is the cause.

[–] ares35@kbin.social 45 points 2 years ago (4 children)

none like that around here. they're all blindingly bright af along the main streets and downtown--probably 4-5x as many lamps in each fixture as actually needed, and going up and down hills they shine right in your eyes because they don't have adequate shades keeping the light 'down'.

residential areas still have the much easier-on-the-eyes sodium vapor lights, though--for now.

I know a guy that very was vocal against street lights in the 90's.

He was/is an amateur astronomer that modified his rooftop to be an actual telescope and the street lamps were angled in a certain way that like 40% of the light produced by them was shinning to the sky, making his observations harder to perform.

He went to my school to warn about light pollution and also teach us about planets and all that good stuff.

I think he became frustrated and quitted because last time I saw anything about him he was all about rescuing dogs from the street. :/

[–] Zoidberg@lemm.ee 4 points 2 years ago

Where I live all street lights used to be low pressure sodium (very monochromatic yellow!) Due to a nearby observatory. Now to hell with everything! It's LED lights everywhere. They're strong and not diffused so all the light comes from a small area meaning instant after image... (Sigh)

Even worse, people now put LED lights on their outdoor house fixtures and all kinds of office buildings pointing UP. Goodbye night sky...

Monochromatic isn't easier on eyes.

[–] atocci@kbin.social 2 points 2 years ago (1 children)

I could definitely be under the wrong impression here, but aren't LEDs monochromatic also?

[–] paholg@lemm.ee 2 points 2 years ago (2 children)

I think they're generally dichromatic (is that the word?). White LEDs are blue LEDs + a yellow florescent coating.

[–] uis@lemmy.world 3 points 2 years ago

LEDs somehow have CRI 0.9, so they are unlikely to be just dichromatic. For comparasion monochromatic light has CRI 0.

[–] Infynis@midwest.social 14 points 2 years ago (1 children)

We've still got a few of those around here. Most have been reported and replaced. But for a time, we had a whole stretch of freeway that was lit up purple. It as sweet

[–] Toribor@corndog.social 6 points 2 years ago (1 children)

Same thing in my area, at one point a whole half mile of streetlights near my house was purple. It was cyberpunk as hell and I loved it.

[–] instamat@lemmy.world 2 points 2 years ago

Me too. I didn’t mind it and assumed it was intentional. A bit out of the ordinary, but different can be good.

[–] schmidtster@lemmy.world 5 points 2 years ago (1 children)

I thought the coating failed to adhere, how would a module affect the colour output?

[–] atocci@kbin.social 5 points 2 years ago* (last edited 2 years ago) (1 children)

Is the coating not considered part of the module? Maybe module was the wrong word.

[–] schmidtster@lemmy.world 2 points 2 years ago* (last edited 2 years ago) (1 children)

I’ve never heard the term used like that before. It’s leds and a driver for them, the only thing I would call a module would be the driver, but modules usually go into large complex machines. Not 2 part devices. The driver would have different modules on it potentially.

[–] schmidtster@lemmy.world 3 points 2 years ago* (last edited 2 years ago)

Yeah it was just a weird term, it’s not inherently wrong… if the lights were multicolored a failed module could make it be different colours, but these are one color and one color temperature. So there’s no way for it to put out different colours.

You just had regular and weird. Now there are flavors of weird.

Taste the spectrum.

[–] pancakes@sh.itjust.works 1 points 2 years ago

I have an assessment next year. I'm hoping for banana chocolate.

White LED bulbs are the devil's work.

[–] Obi@sopuli.xyz 22 points 2 years ago (1 children)

Can't stand them for street lighting, just makes everything look cold and uninteresting, I'll take the warm ones over them any day.

[–] solinus@lemmy.cafe 4 points 2 years ago

Where I live they did put up slightly warm tinted LED ones

Man it's been a while since I've seen them at Starland.

[–] FreeAZ@sopuli.xyz 6 points 2 years ago

I saw them at Starland the night they played all of "Everything Went Numb" and "Somewhere in the Between". Incredible show, almost broke my leg when a crowd toppled over.

Really sad I missed the Bandits of the Acoustic Revolution show a few years ago.

[–] Semi-Hemi-Demigod@kbin.social 5 points 2 years ago

I've seen them probably fifteen times over the years. Best live show I've ever been to. Hopefully they get the new album out soon and go on tour again

[–] HobbitFoot@thelemmy.club 4 points 2 years ago

Is it because Keasby nights aren't that dark?

[–] peopleproblems@lemmy.world 36 points 2 years ago (1 children)

You know what's funny? My son was evaluated for is as there was some concern because of a lot of ASD in my family.

I told them "ok, but he's really just pretty similar to me". I haven't been diagnosed. I do have extremely bad general anxiety.

And his evaluation showed no risk, but some possible connection if anxiety couldn't be ruled out. Turns out, anxiety couldn't be ruled out.

Yep. I'm so anxious it looks like ASD apparently.

[–] yote_zip@pawb.social 25 points 2 years ago* (last edited 2 years ago) (1 children)

This ~~is really similar to~~ reminds me of this post, which I think about a lot.

Edit: hopefully slightly more accurate

[–] peopleproblems@lemmy.world 12 points 2 years ago

Except that's like the opposite of what I said.

I was evaluated and never diagnosed with ASD, but I had GAD and ADHD. I predicted, correctly, my son would be the same.

[–] PopcornPrincess@lemmy.world 16 points 2 years ago

I had no idea streetlights would create such controversy. Look at these passionate responses. Lemmy used to be peaceful. Way to go OP!

[–] ObviouslyNotBanana@lemmy.world 15 points 2 years ago

Yeah but that's just one guy! /s

[–] ElleChaise@kbin.social 12 points 2 years ago (2 children)

Seriously, what is up with these streetlights?

[–] Crashumbc@lemmy.world 7 points 2 years ago (1 children)

Good sales men. And they are EXTREMELY efficient compared to old lights, last longer, and easier to maintain.

[–] SomeAmateur@sh.itjust.works 1 points 2 years ago

Yeah LED's are amazing, I just want warmer light from them.
