What, anyone over the age of 8?

Still have them on my street

Yes introduced on smoggy parts of the motorway network. 😊

​@@nicks4934Yes, and in the 50's too, before they had motorways. Must have been a decision by Claire Voyant.

On those suspended wires remember? M62, M61 1970s. Great days 😢

have seen a green version of these in the Netherlands and they are great. visibility is just as good or better than traditional white and without the glare too

It's also possible that they reduce ligth pollution. I would need to check this fact, however. Us astronomers use red light, because it doesn't interfere with our equipment as much. So, red lights would mean darker/more stary nigth skys which is also a huge win.

Anything is better than that hellish yellow sodium that caused eyestrain while wiping out nightvision. Although they should ALSO do something about ludicrously bright car headlights that wash out nightvision. An air rifle would do it, I think.

Or just go back to Sox? Better than LEDs, they’re all so cheaply made and fail after a year 😂

@@TheCORC964 this isn’t strictly doesn’t to them being LED, more the fact they are designed with the cheapest cost in mind, and as such the LEDs are overdriven for a greater light output with less chips being used (the pence these cost adds up when mass produced)

It's always good to hear from an actual user. Nice comment.

As a light haulage driver, I second this comment..

what is a bias voltage?

@@SamSitar Use less energy I think.

Although red LEDs are about twice as efficient as white LEDs, the lumens per Watt are less for red LEDs because the eyes are less sensitive to red light than other colours including white light. So point (1) doesn't present the whole story.

What is a meme ? funny or otherwise. Thanks.

@@SamSitar its the voltage that is required to make the LED turn on.. RED 2.0V or less Ultraviolet LEDs 3.0V + Ultraviolet leds are what are used to make white light by illuminating phosphorus.

Always nice to have a local comment to clear things up! ;-))

Thank you for the clarification. :)

Are you a Bat?

@@willtricks9432I’m not saying I am, but I could be 🫣😂

@@joshuawarner3641: The flowing black cloak really suits you!

LED's are typically one frequency unless the colour is made by a phosphor coating, which most white ones are.

🤣

He sure does good on him!

They are at the junction of A38 and A4104 at Ryall (Upton on Severn). Look really good!

@@davidbagley3678 it was exactly that roundabout

To be fair Malvern is pretty weird 🤣

@@davidbagley3678 I went through the new roundabout in March and me and the missus were wondering why it had red lights, then last night we noticed that they'd changed the lighting on a roundabout just down the road from us in Evesham, we now know the answer.

Yes, red light is supposed to be good at protecting night vision as the pupils don’t constrict as much.

Also to note, I’m not suggesting that red headlights would be a good idea, that would just be confusing

@@Living_Life_RN Please, no! I like proper white light for seeing cars, pedestrians and other things that I need to avoid when driving, whether it's white street lights or white car headlights. I find the monochromatic yellow of low-pressure sodium or the red of LED very tiring on my eyes, because they struggle to make sense of objects which are illuminated by just one colour. For that reason, I prefer the more modern high-pressure sodium lights with a pale peach cast and a broader spectrum to the traditional low-pressure sodium lights which are just a couple of spectral lines and so are intense orange.

@@Mortimer50145 You don't need colour rendering from street lights, that's what your headlights are for. Monochromatic lighting from low pressure sodium is the best as it cuts through fog and mist far better than white light. My other half has night blindness, which means that she can't see at all in the awful colour temperature of LED street lighting.

@@TestGearJunkie. We'll have to agree to differ. I prefer white light and find monochromatic low-pressure sodium lights very tiring on my eyes. The same applies to a red/orange photographic safe light: I found I could work in a darkroom for only an hour or so before my eyes started to hurt. I find high-pressure (peach coloured) sodium lights much nice to drive by than low-pressume (monochromatic orange). But LED streetlights are the best for me. But I accept that other people may prefer something different. Headlights are only any good for the distance that they illuminate. If you've got to dip your lights because of cars ahead (same or opposite direction) then the only thing that will illuminate anything beyond their beam is the street lights.

​@@Mortimer50145Yes but both types of sodium are being phased out everywhere but they're still better than any LED alternative.

I spotted that. He's showing his age coming out with a joke like that... but then, so am I for understanding it 🤣

We like to make Greta cry.

Careful, that's borderline common sense right there.

It helps to deter crime, if only slightly.

Or maybe we could have some regulator on the streetlamps and it would adjust their light output according to light conditions on the street. I see nothing wrong with screens and displays being on after closing hours as people, in cities at least, are more active in evenings and night than they were let's say three decades ago.

Sometimes commercial properties get a discount on their electricity if they use over a certain amount. I once worked somewhere that would leave things on all night, so they could use enough to get a discount.

And blackout blinds to block it out mess with your circadian rhythm on the other end too. Though daylight alarm clocks are a thing, that being an alarm clock that lights up in the morning instead of, or as well as, an audio alarm.

@@TheAkashicTravelleryep, bought one of those clocks and a decent blackout blind last week. I have an LED street light outside my room and curtains just weren’t cutting enough of the light out. Never felt better tbh

Pairs of what?

Same

Same with ships and even small yachts. Edit. Even without the periscopes 😂

I would suggest that you sleep inside so as to avoid the terrible LED lights, it will be to your benefit and much warmer than sleeping outdoors

@@TheMatchlock My condolences, I'm sorry you live in a house without windows.

​@@TheMatchlock Imagine living in a place where LED lighting has been invented, but curtains apparently haven't. 🤷🏻‍♂️

@@Technaudio To be fair, curtains often don't cut it for these lights, even blackout blinds can struggle unless you have a complete seal around the window.

@@Croz89 And cutting out all the light like that has the downside of messing with your circadian rhythm on the other side.

You're wrong, the colour of fire (2200k ish amber) is the maximum on the colour range that humans should experience after sunset, everything below that, like these red led's, is even better. The way we live our modern life with screens and hyperlighting past daylight has a negative impact on our brains.

@@DavidColex IF AND ONLY IF they are intending to sleep. Driving a car is NOT something you want humans to be sleepy for. Car crashes are known to have a VERY negative impact on brains (and bones, and muscles, and organs, and skin). Street lights should absolutely NOT be red, they should not be amber, and they should not be monochrome.

@@jonc4403 Bollocks, we used amber lights for decades, and I see no decrease of sleep-related accidents after we moved to the 3-4000K LEDs

@eljay5009 Something to do with the LED's natively emitting that horrid blue light and produces more lumens per watt consumed. Any other colour LED has to have a coating on it to make the new colour, and that reduces the lumens a bit. I've seen quite a few replacement LED streetlights around Leicestershire are now semi warm white when the original LED fixture fails.

and I imagine as well that the light from the red LEDs would be easier than that from the white LEDs to filter out for telescopic observing since it will be at a narrower wavelength range

I've just retired as a driver of 46 years. Once upon a time, quite a bit of consideration was given to the placement by the authorities of lights adjacent to running lines. Especially red yellow or green, for obvious reasons. That went out of the window years ago. Now anything goes! These red streetlights can't be worse than the current crop of white LED ones, which directly dazzle, but also at the same time, put very little light on the ground. They make gloomy pools of mystery interspersed with completely dark and unlit tranches. The old sodium ones were way better at doing what they were put there for! I like the idea of these red ones for the bats, I like bats, but where I live, they aren't bothered by bright lights and they'll be out at dusk aback of my house as usual. On another note, why, when using elevating lights on night worksites, are they never put up to full height, even when there is nothing to prevent it? It's always been like that even in the days of the old pump up 500w halogen arrays. They are always at bottom and blind drivers passing worksites, instead of being up there and shining down, even worse when it takes longer to pass due to associated TSRs.

I think I'm hilarious :D

Thanks a lot mate!

Red ditch...lol

That would get a DMCA copyright strike - and nobody wants to get stung.

@@David_Crayford Indeed. I played it locally anyway!
