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.

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. :/

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.

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

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

parent

[–] 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.

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.

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 child)

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

parent

hideshow 2 child comments

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

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

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.

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.

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.

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

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.

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.

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