LEDs causing more Light Pollution

[Laika]

Its probably not a huge priority in terms of our environmental awareness, but its none the less still interesting to see just how quickly changes in our behaviour are visible even from space.

Any Thoughts?

It does interfere with astronomy and it's too bad but we have a gigantic list of things needing to be dealt with right now.

Should we go back to burning more fossil fuels and filling landfills with the old style bulbs?

Well, the Owls will hate us less that way.

Economic and effective lights are a real breakthrough towards eco-energy apps.

And our best telescopes are not affected.

I think that LEDs are the future, honestly.

I don't like LED headlights. They are too far into the blue spectrum, so they hurt more. If they were a little less white and a little more towards the yellow or green portion of the spectrum that would be a good thing.

Yes.......
The very worst headlights can be some bicycle headlights which are not always focused to the correct depression and really do blind oncoming traffic and pedestrians.

But tail and stop LEDs are just amnazing and must surely be reducing 'rear-end' crashes.

I am still amazed at the brilliance of a modern pocket torch, and how long a battery can last. There just doesn't seem to be much point in bothering with AA and AAA rechargeable batteries now.

I noticed a month ago, when they replaced one of the streetlamps that it was quite a bit brighter. It's obviously LED and white light. There's still some older lamps around, so you have a side-by-side comparison.

Honestly though, there's downsides to pretty much everything... We have to pick whatever we think is best, until there's something better.

The problem isn't the technology itself, but how people use it.

It doesn't surprise me. They are very bright. For the past few years I've joked that this Amish family has the brightest light in the county, because at night you can see this LED light coming out of the dinning room (it's what it looks like, anyways), and clearly see everything in that room as you drive by. It's mind boggling just how bright they can get.

LED lights make good flashlights but for general lighting or headlights they are too bright.

They don't have to be.
I have replaced nearly every bulb in my house with 9w bulbs. Plenty of light at a fraction of the juice. It seems that people often increase the candlepower unnecessarily instead.

LEDs are the present.
- They last longer.
- They use less energy.
- They lack the spectrum which damages art work (unlike fluorescents).
- They're cheap to buy & maintain.

What's troubling there? That the stars are harder to see from the city, or that amateur astronomers there see less? Most professional telescopes are far from cities or in space, and would be largely unaffected by light pollution in cities. The rest seems relatively unimportant,

I found it encouraging to see how much of the world is making progress in energy efficiency. Those lights might still be mostly powered by electricity derived from fossil fuels, but it's still a step in the right direction.

LED or even regular light bulb interferes with human spiritual perception and contributes to rise of atheism, imo. other types of pollutions, food air... too.

They have absolutely zero impact on mine.

Yeah..........
An' all that an' all.........
Innit.

it definitely affects my melatonin production...e.g :

Apologies. I was unaware that you define "spiritual perception" as health.

our CNS has organs of perception built in, e.g. pineal gland that can be rendered non operative by pollutions.
