"Green" Idiocy- Lightbulbs, Eye Health, and Sleep

The last week or so I have been looking to purchase some lightbulbs. I have been buying halogen bulbs from Walmart and now they don't have any on the shelves- only LEDs.

Besides being really expensive up front LEDs aren't good for our eyesight or sleep. Something I looked into because I have a genetic predisposition for macular degeneration.

This isn't new information, it has been known for awhile:
A 2012 Spanish study found that LED radiation can cause irreversible damage to the retina. A 2019 report from the French Agency for Food, Environmental and Occupational Health and Safety (ANSES) warned of the “phototoxic effects” of blue light exposure, including an increased risk for age-related macular degeneration.
Halogens have been an option to avoid LEDs:
Before replacing your home or workplace’s indoor lights with LEDs, consider two downsides:

LEDs do not give off near-infrared radiation, which is necessary for health
They emit large amounts of blue light, which disrupts sleeping patterns and over time can contribute to eye disease.
One of the benefits of LED lights is that they are cooler to touch.However, this is part of the problem. LED lights do not give off near-infrared radiation. This type of radiation comes from the sun; it is also emitted by incandescent bulbs and halogen bulbs.

Near-infrared heat is important for good health. It deeply penetrates the skin, even through clothing. Near-infrared light activates mitochondrial ATP.1 When this form of light strikes the retina, it primes the retinal cells to repair and regenerate. LED lights cannot do this. Therefore, they should not be the primary source of light throughout the day.

Dr. Alexander Wunsch, a leading researcher on photobiology, recommends purchasing a low-voltage incandescent halogen lamp to use on dark evenings.Fix it to operate on a DC transformer. Ideally, you should be able to adjust the output to between 6 volts and 12 volts. DC (Direct Current) has no flicker and no dirty electricity. Also, you can dim and brighten the light as needed.4
I don't have special lamps, but I do have 40W equivalent halogen bulbs in my bedside lamps.

Besides emitting blue light LEDs aren't constantly on. They flicker (turn on and off quickly) which is part of why they are so energy efficient.
Flicker. Because LEDs are digital lights, they flicker. Most people cannot perceive this. Color-changing LED lights and dimmed LED lights turn completely off and completely on, very quickly. Flicker is “biologically active. And flicker is something that is very harmful to your [biology],” according to Dr. Alexander Wunsch, an expert on photobiology.8 Old TVs had noticeable flicker; modern flat screens still have flicker, but it is much faster.

Flicker may cause problems for people who are sensitive to light, such as 21% of people with chronic fatigue or Lyme disease. Some newer lamps have less flicker problems.
If you can't get halogen bulbs it seems that warm white double walled fluorescents, candles, and sunlight are your better options.
The ‘double-envelope‘ compact fluorescents, which look like a regular light bulb, are ok. But exposure over an hour to unshaded ‘single-envelope’ compact lamps can exceed radiation guidelines. These are the bulbs that show the spiral shaped bulb. 3 to 6 hours exposure daily is equivalent to a 10% to 30% exposure to carcinogenic radiation.

In addition, in product safety testing, some of these single-envelope CFL’s were found to have cracks in the phosphor coating – which might permit UV leakage. Avoid this by buying only double-envelope CFLs.11
But, katya why can't you just buy halogen bulbs? Did a search; sad, but not surprising:
Retailers will have to replace their stocks of halogen lightbulbs with more energy-efficient alternatives, such as LEDs or compact fluorescent bulbs. ...Why are halogen bulbs being banned? They are extremely inefficient in their use of electricity.May 15, 2020
Let's save electricity and to hell with any negative consequences.



ETA: Walmart still had some available online for delivery. Fingers crossed they make it here and are undamaged.

I've seen a lot of obese doctors too.

Did he actually make a case to you that LEDs are okay?

Yup. I hate the floaters I get when I go for a late night walk and get blasted by those nasty leds on new cars.

LEDS should be fairly safe since most normal people arent looking directly at them for long extended timeframes.

Thats why more and more screens (computer/mobile) are offering blue light modes.

Because...

- we live in a society
- who wants to live forever?

Also the studies seem pretty weak. What exactly are the dangers? Doubling my risk of a certain retina disease from .001% to .002%?

LED super-bright headlights on cars bug the chit out of me.

You don't need light as bright as the sun to drive down the fukkin street.
I have sampled every language and French is my favorite to curse in.

They're all gone. Legislated out of existence. Aftermarket ones are fading in popularity because they're so unreliable.

I listened to the whole thing.

Sad to say raj that Japan also has done away with incandescent lights. Began around 2015 and said they meant to complete the switch by 2020.

The old bulbs do produce heat and not just light, but as you said that isn't always a negative (cold weather/cold climate).

Did you know that incandescent bulbs used to last longer until a cartel was formed to limit them to only last for 1,000 hours?

https://gigazine.net/gsc_news/en/201...hoebus-cartel/

I don't care if they use LED lights for things like streetlights or inside appliances. I have LEDs for some ceiling fixtures, but care less about those because I don't like ceiling lights much and don't use them often- I prefer lamps. I put on ceiling lights just to do tasks like cooking or cleaning, not to hang out and watch videos or read. I put halogen bulbs in the lamps.

Wiki on the current state of lightbulbs (phasing out/banned):
https://en.wikipedia.org/wiki/Phase-...nt_light_bulbs

IMO businesses would be better off increasing natural light with things like windows, sky lights, and "light tubes"...like a skylight for multi-level buildings. In our homes most people don't have lights on around the clock everyday and lightbulbs don't effect electricity usage enough to be so militant about what kind you can choose.

HVAC uses a lot more electricity than lighting. Requiring efficient building standards that include good air exchange for new buildings and working on retro-fitting existing buildings would save a lot more energy.

Only allowing certain types of bulbs is roughly equivalent to the government controlling what temperature you are allowed to set your thermostat for.

Over the years of speaking with many "Green" people, this is a recurring theme that I have noticed, and unfortunately it turns off a lot of people from these ideas.

"People should stop eating meat and just go vegan."
Ok but what about nutrient deficiencies, the land required for crops, etc.
"Well we won't have to worry about that if the planet goes to chit anyway."

"We should cut off petrol completely and go full green energy."
Ok but will it be sufficient to amount of energy required to keep society going, what about production cost, what is the shelf life of the material, etc.
"Well we won't have to worry about that if the planet goes to chit anyway."

There is an objective for a lot of the green crew and as long as its met then nothing else matters.

Good thread katya422, I wasn't aware of the phasing out of old school lights.

This is a good and underrated point. Mental health is not talked about enough when it comes to lighting at home, imo.

Mental illnesses aside, when's the last time anyone went out in the sun and their mood didn't automatically improve?

Like many things "it depends". In this case on your personal biology + the amount of exposure. I saw one source that put the danger zone at 45 hours, maybe based on people working in offices w/LED lighting. Not sure how much it has really been looked at to determine where the risk moves from negligible to moderate etc.

Your eyes are actually the same type of tissue as your brain. This podcast is kinda long, but also packed with information including info about light and the circadian cycle.

This neurologist recommends that you get outdoors and get some sunlight when you wake up in the morning while the sun is low on the horizon. Says it keeps multiple biological systems ticking along in good order. Also talks about "people susceptible to eye disease" needing to avoid bright/direct light and to take more care than most w/sunglasses.



random: Besides the predisposition for macular degeneration I've also got a genetic marker for not converting beta carotene to vitamin A and I wonder if those two facts are related.

And of course it isn't incandescent. I do use a dark reader app most of the time though.

I think you missed my point. Stuff like danger zones and increased risk percentages just don't matter much if the baseline is low, and people routinely obfuscate the baseline because nobody cares about stories that go "this thing we all thought didn't make much of a difference actually doesn't make much of a difference". So instead we get drama where there's no point for drama.
