I would love to see us bring back incandescent bulbs. We are being bombarded by blue light. Regulated circadian rhythms through warm Incandescent light is so important and goes hand in hand with overall health.
Thank you! I have chronic migraines and I simply cannot use any ceiling lights in my house because of this. This is such an easy thing that is so often overlooked in accessibility conversations.

LED lights are available in a wide range of colors. Many major retailers often stock bulbs with higher Kelvin ratings (5000K and above), which can be unsuitable for both indoor and outdoor use due to their harsh, blue-tinted light. Instead, consider using bulbs with a Kelvin rating around 2700K, which emit a warmer, more orange-hued light. You can further adjust the color and brightness of these bulbs or non-interchangeable bulb fixtures using theater gels. Returning to incandescent bulbs is not a viable option due to their inefficiency, consuming approximately ten times the power to produce an equivalent lumen output.

Led lights are harmful to our health, research it. I only use incandescent in my home, they may not last as long as LED but my health is more important

I totally agree @Angela524! 
David Asprey and Dr Jack Kruse (brain surgeon) talk about the harmful effects extensively.

LED bulbs, like any product, can vary in quality. Low-quality bulbs may flicker in ways that are not visible to the naked eye but can still have negative effects. Essentially, you get what you pay for. If you are concerned about LED bulbs, opt for high-quality ones with a warm color temperature (below 3000 Kelvin ) and a CRI of 90 or higher. Flickering can also occur due to dimming, as LEDs are not inherently dimmable and require technology called PWM, which rapidly turns the power on and off. The longer the power is on compared to off, the brighter the bulb will glow, and vice versa. Therefore, making this blanket statement about all LED bulbs is inaccurate. While I don’t consider myself an expert, I have been in the industry for several years and have firsthand experience with various forms of LED lighting.

LEDs can have a longer lifespan but sometimes don’t for several reasons.
- Manufactures overdrive the LED elements causing excess heat.
- The bulbs are not rated for the fixture or location they are installed in (indoor/outdoor and if they are designed for fully enclosed fixtures or not.
- Frequent on and off can cause premature failure of the power circuit that is built into the bulb.
- Bad source power.
- Bulbs that are left on for very long periods or indefinitely.
Most of the causes of premature failure are ultimately the result of bad power and or heat. For this, lifespan is not a good selling point even though the manufactures like to run with it.

Thank you! I can’t stand the light of an LED light. They are especially bad when used in tail lights. I almost never drive at night anymore because of the LED tail lights.

So the main want for this suggestion is due to the excess blue light in the spectrum, lack of deep red, IR and NIR wavelengths, the flicker associated with less than ideal rectification or pulse width modulation driving the leds and the non-linear waveform it puts back onto the power grid. Ok, then those are the areas that need addressed which can be done with a changes in product design and emissions requirements. We don’t have to go back to incandescent to achieve that.
- Include IR emitting LED chips in full spectrum lamps. UVB 298nm band for the ideal vitamin d precursor production in small quantities.
- Use constant current drivers to maintain steady voltages and currents to keep the LED in an on state so flicker rate is very low or non existent.
- CRI index of 96 or better to maintain as close to natural sunlight with no huge peaks in any one range as possible.
- Include Optical sensor or internal clock synced to the Naval Atomic clock ( receive only, no wifi, zigbee or anything else that adds microwave emissions ) to shift lamps over the course of the day to match daylight color temperature to maintain circadian rhythm. Can be time shifted for night shift worker alertness if needed.
** Correct the non-linear waveform distortions on the input power created from rectification. This will improve operating costs and efficiency on all equipment connected to the grid. This is currently a major problem with LEDs and a number of non-linear loads today adding unnecessarily high harmonic currents everywhere.**

Using programs like flux on your computers and devices to make the color temperature warmer reduces blue light. But your eyes also need red, nir and IR wavelengths for proper functioning and health.

This one is hard. The city probably looks at the pro’s and con’s on this one. It all comes down to money. Should the city keep lights on at night even past a certain hour to keep everyone safe but use LED lights? Or should we use incandescent light so people are more comfortable visually, but safety will be on the back burner because keeping them on all night long will be costly for the city (plus it’ll just come out of our pocket via property taxes or income taxes, etc). Imagine going the incandescent light bulb way but the city puts in curfews for our safety. That would be nuts!
Just buy warmer LED lights. LEDs are so superior in basically every way.

Incadescent Bulbs need to be legalized and should never have been banned because LED lighting is not friendly to people on the autism spectrum. It hurts their eyes.

Acute damage to the human retina from typical exposure to blue or white LEDs has not been demonstrated.
Light-Emitting Diodes (LEDS): Implications for Safety
International Commission on Non-Ionizing Radiation Protection (ICNIRP)
*Health Phys . 2020
The amount of blue light emitted by typical LED devices (is not enough to cause significant damage. Exposure levels from regular use are far below those that would cause harm to the retina, especially when compared to high-intensity sources of blue light such as sunlight.
Potential health hazards of blue light from digital screens
Clinical & Experimental Optometry, 2015.
Although high levels of blue light exposure may contribute to retinal damage over decades of excessive exposure, day-to-day exposure to LED lighting is not a substantial risk factor.
Eye & Contact Lens: Science & Clinical Practice, 2017.
There is no substantial evidence to suggest that normal use of LED lighting —such as lighting in homes, offices, or streetlights—leads to any long-term health issues.

If you search for healing light bulbs, & have a lot of money, you can still find a few bulbs!

I agree @Angela524. LED bulbs are a health hazard. It gets my blood pressure going off the chart every time I have to replace a LED bulb (at $3.50 a pop) every 12 months, when I have some good old fashioned Edison Base incandescents (at $0.29 each) which seem to last for decades.

That’s the point of my above post, product design regulations can make them much better on quality and spectral output range to be where they need to be in order to NOT be a health hazard.
Yes!! The moment I learned about this website, I signed up to make the same request.
I started a petition on change.org(/saveincandescents) which has over 2,000 signatures. Trump saved incandescents from being banned back in 2019, and I believe he will do it again, especially with RFK on his team, but it needs to be for good this time.
But not only do I want Trump to save incandescents, I want him to take it a step further and ban LEDs. I might make a separate post for that. Because it’s not just incandescents that have been replaced by LEDs, but halogen car headlights, LPS and HPS streetlights, etc. There should also be specific policies to protect children for light-up toys similar to what they have in Europe.

It is a total travesty that a stroke of the pen can eliminate an entire industry. Let the market decide.
