AMA Warns of Harmful Health Effects of New Environmentally Correct Streetlights

Caution — like a lot of moonbattery, environmentally correct streetlights can be hazardous to your health:

The American Medical Association is concerned that the glare, the high blue light content of “energy efficient” LED streetlights being rolled out across America, might be suppressing drivers’ night vision, and causing other harmful health effects.

From an AMA press release:

High-intensity LED lighting designs emit a large amount of blue light that appears white to the naked eye and create worse nighttime glare than conventional lighting. Discomfort and disability from intense, blue-rich LED lighting can decrease visual acuity and safety, resulting in concerns and creating a road hazard.

In addition to its impact on drivers, blue-rich LED streetlights operate at a wavelength that most adversely suppresses melatonin during night. It is estimated that white LED lamps have five times greater impact on circadian sleep rhythms than conventional street lamps. Recent large surveys found that brighter residential nighttime lighting is associated with reduced sleep times, dissatisfaction with sleep quality, excessive sleepiness, impaired daytime functioning and obesity.

As for the animals that enviro-Jacobins so piously prioritize,

The detrimental effects of high-intensity LED lighting are not limited to humans. Excessive outdoor lighting disrupts many species that need a dark environment. For instance, poorly designed LED lighting disorients some bird, insect, turtle and fish species…

As a rule of thumb, if it has been imposed by our moonbat rulers for ideological reasons, it is probably harmful.

    There is a remedy for that – which our grandparents and their parents and their parent’s parents all knew about. It is simply to close the drapes. That will take care of the outside lighting coming in. Problem solved.

    I hated CFLs for technical reasons, and not just because they were being forced on us. And unlike CFLs, LED lights really do last a long time. This “blue light” thing is not new—it’s been in the medical literature for decades.

    Because of its higher frequency, blue light does not focus as clearly as red in the human eye—but that’s when it’s purely blue light. Even the “room glow” from high powered blue lasers is considered potentially hazardous.

    But if “blue” LED street lighting is keeping drivers awake, well, I can’t see the problem. Fluoros where selected for office use for the same reasons.

    “White” LEDs have gone through a number of phases. The most recent design encases the LED in plastic with a material that changes the color to a “whiter” kind of light, and that produces color spikes. Many artificial lights have “unnatural” spectra, but lighting technology evolves all the same.

    Go back to incandescents? No thanks. I have a mix of “blue” and “yellow” LED lighting in my home. (Blues tend to be near windows.) Bluer lighting is also favored in Japan, while yellow is favored in the West. An argument could be made against the yellow lighting, too.

  3. Jodie says:

    Good points! I have an LED light on the side of my house that I leave on all of the time. It has been on for about ten years and is still going strong. The CFL’s that I tried to use years ago, always burned out very quickly and were terrible when it came to reading or seeing well in the orangeish light.

  4. Tom says:

    Kind of like the big ecologically-correct push to swap out those bad old incandescent traffic lights and replace them with LEDs.
    Now, when, years later, some genius figures out that the LEDs don’t put out enough heat to melt accumulating snow and that they quickly become clogged and not visible when it’s blowing snow and cold outside, which, believe it or not, happens quite often in a lot of America….now you can buy these in surplus, for less than $15/each, and less than $12/each if you buy the full red-amber-green set.
    How much taxpayer money was spent on THIS boondoggle, I wonder…

    “…white LED lamps have five times greater impact on circadian sleep rhythms than conventional street lamps.”

    And just what is a “conventional street lamp?”

    Orange-yellow sodium lights?
    Mercury-vapor lights with their high UV content?
    The yellow incandescent ball in the sky from the 1940’s and 50’s?
    Florescent lights?
    Neon?
    Burning gas lamps?

  6. Mr. Freemarket says:

    “For instance, poorly designed LED lighting disorients some bird, insect, turtle and fish species…”

    I think I heard a similar statement made prior to the invention of LED lights.

    Sadly, I just don’t care. Now if it would disorient invading Muslim hoards, then we might have something.

  7. dott says:

    That’s three strikes: fire-starting, room heating halogens; mercury-laden, blindness producing CFLs; and, now — blue-light blinding, sleeplessness-producing LEDs. Are we done with this crap yet?

  8. dott says:

    Good question, though I think we can eliminate a couple off your list right off the bat… The yellow incandescent ball in the sky from the 40’s & 50’s?? Were you meaning the SUN, by any chance? Or a meteor over Roswell? Hard to tell.
    Either way, neither has ever been used as a street lamp… I don’t think fluorescent, or neon were either. Gas hasn’t been “conventional” for street lamps a long time, though a re-thinking of that concept might be in order.
    That leaves mercury-vapor, or sodium.
    Most mercury vapor lights were cast out in the 70’s and 80’s, their elimination sold to the public by the claims that the “less harsh” (aka dimmer, diffuse) pinky-peach sodium lights had the “scientifically-proven” effect of produce less criminal activity”. Should have tested them extensively INSIDE government buildings and the Capitol.

  9. dott says:

    They work o.k. in the less blizzard-y parts of the country, though we lost tons of them during the first hurricanes that came along after their installation, probably due to the much lighter cable used on them. I have noticed that now there is a sort of mini-spool thingy on the lines that both helps prevent swaying, blowing and bouncing of the lines a little bit, and also holds some extra cable, which would reduce the tension quite a bit, just in case it is needed.

  10. dott says:

    Drapes would be a very bad idea for nighttime drivers– like truckers.

    Examples of incandescent street lights that I was referring to. Typically they were relatively high wattage incandescent bulbs with a very yellow color temperature in order to last a long time. Every attempt since then at street lighting has been an effort to improve electrical efficiency to decrease a city’s electricity costs.

    Mercury vapor lights have an efficiency of 35 to 65 lumens/watt.
    Low pressure sodium vapor lights have an efficiency up to 200 lumens/watt.
    LED lights are being sold on the basis of energy efficiency and longer life resulting in lower maintenance costs.
    We shall see, since LEDs are a rapidly developing technology. I suspect that the anti-LED efforts are led by those who manufacture sodium and metal halide street lights.

  12. rambler says:

    We were just fine choosing the bulbs we wanted and then the gov came along to botch everything up.

  13. Bosun Higgs says:

    You’re right. We shouldn’t disturb their ability to sleep behind the wheel.

  14. Spiny Norman says:

    So filter the damn lights. How hard can that be???

  15. Rotohammer says:

    I want to preserve dark skies, which would seem like a tree-hugger notion. However, these LED lights are a perfect example of how moonbat policies just make things worse.

    These full spectrum lights are just wrong. I wonder if they could be tinted to match the sodium lights. They don’t need to be as bright as they are. Having a more narrow and uniform wavelength works better in fog because the light diffuses less.

    Narrow band astronomy can be done in light polluted areas because the interesting wavelengths for astronomy fall outside the sodium color. LED light pollution will make that impossible.

  16. Rotohammer says:

    Does paintball gun ammo come in yellow?

  17. MAS says:

    It has been said that an honest man’s reward is his pillow. I must be honest because pretty much all of our home lighting is LED and I still sleep like an olympic caliber nap king. Might this be more Chicken Little science application?

  18. MAS says:

    Yes. So does die or paint in a tied off balloon launched via slingshot.

  20. cliffyk says:

    Manufacturers have spent gobs of R & D money on making the output of residential LED lightng mimic the color temperature of incandescents. The light produced by the LED lighting is not at all similar to the stark “white” produced by high intensity LED exterior lighting–if it were you would not like it either…

  21. grayjohn says:

    More envirobullshit.

  22. grayjohn says:

    It’s what they do.

  23. dott says:

    It impairs their ability to sleep once they are OUT from behind the wheel, Boson, due to the loss of melatonin, which makes the chances of falling asleep once they start driving again more likely. Loss of melatonin — and sleep as a result, can also lead to depression as well. Depression, sleepiness, and an 80-ton vehicle is not a good mix, which even you should be able to concede. Bad enough that most cabs have computer blue light flooding them, and soon most cars will as well.

  24. dott says:

    A blue light filter for my computer work after nightfall has certainly made it easier for me to get to sleep when it’s time, that’s all I know.

  25. rambler says:

    Because they can’t seem to do what they are supposed to do so they inflict themselves on the us.

    “AMA Warns of Harmful Health Effects of New Environmentally Correct Streetlights”

    ECO-FASCISM FAILS ONCE AGAIN….

    Remember this:

    “Energy-efficient CFL bulbs cause skin damage, say researchers”
    …another INCONVENIENT TRUTH about eco-fascist products. The GOOD news: this is not as bad as being burnt to a crisp in an OBOZOMOBILE VOLT lithium battery fire! (The latter is fully covered under OBOZOCARE – with approval of a DEATH PANEL, of course.)

  27. rex freeway says:

    I live in the midwest where we have the full range of weather and temps. Incandescent flood lights had to be changed fairly often, were cheap, but used energy. CFL’s lasted longer but cost more and took forever to get to full light in winter. Had one sodium on my garage that lasted forever. Never tried Halogen. Will try LED when CFL’s go out. I live in a neighborhood that still has sodium. We are the last street with nothing but woods to the south and west of us. The light pollution still removes many stars. With lack of crime in my hood I would love to see dimmable lighting. But who would be in charge of dimming and for what reasons?

  28. Grampa2 says:

    I take it you live in your home with the blinds drawn and never walk outside. Its nice to take a walk on summer evenings without being blinded or feeling like its exercise time in the prison yard.

  29. pogeybait says:

    Well in winter the old incandescent lights put out heat which melted the ice that formed on traffic lights. The LEDs do not and so the lights fill up with ice and snow and should be considered stopsicles.

  30. Jodie says:

    Ditto for you dolt. My comment was about people shutting out the LED street lighting, if they are having problems sleeping. Why would delivery drivers and truck drivers be wanting to sleep while they are driving?

  31. Jodie says:

    Grumpy2,

    What are you talking about? Unless I am reading it wrong, the story is about people not being able to sleep, due to the street lighting – so I am saying to shut the light out when you are trying to sleep. Is that so hard for you to understand?

  32. dott says:

    By the way, being relatively new to Discus, just wondering are people always this “intolerant” and uptight, that they immediately lash back and call people names right off the bat?

  33. Jodie says:

    dott,

    It is you that is provoking. I only react when attacked. Your reply to my comment was rude, and your responses on this thread make you sound like a know it all.

  34. 762x51 says:

    Meh, we have reached the point and zoomed right past it where, regardless of what anyone does or doesn’t do, some overly sensitive asshole with an ax to grind will bitch about it. Then a bunch of spineless cowards will trip all over themselves in a futile attempt to placate the alleged victim, usually with other peoples money.

    Have you noticed that not opposing it hasn’t worked? Opposing does not equal some mealy mouthed political operative saying crap they know wont happen with a strongly worded letter to follow.

  35. dott says:

    Um,

    “Recent large surveys have found that brighter RESIDENTIAL nighttime lighting is associated with……”

    followed by a list of effects — then,

    “There is a remedy for that … It is simply to close the drapes. That will take care of the OUTSIDE lighting coming in. Problem solved.”

    Jodie, you were the one who initially crossed the beams, and then jumped on the subsequent posters, and upped the ante with an insult.

  37. Bosun Higgs says:

    I know all about the melatonin, Dott. I also know lots of people with night shifts and airline workers who routinely flip their daylight patterns. And they all sleep just fine and haven’t committed suicide or gone postal.

  38. grayjohn says:

    There were a few of those on my street when I was a kid.

  39. NIdahoCatholic says:

    LED is available in other color temperatures. I’ve ordered and installed quite a few 3000K LED’s for my workplace.

  40. dott says:

    Doesn’t happen to everybody, never said that. A lot of people, as you say, work nights and do fine for a very long time, like an overnight security person, 2, actually that I know of, but they know how to. They have their rooms set up for total darkness, or close to it, they have blocked out all disturbances, short of atom splitting loud, with earplugs or soundproofing, phone shut off, cranked up the A/C, and will still get up early enough to bask in some natural sunlight…even if it’s over an early bird dinner out of doors. It can work, but — if and when they have a real rough night, or a few of them, watch out for a grizzly deprived of enough hibernation!
