People are supposed to get sunlight. Infrared light does a lot of work for us. We don't get that from LEDs which is part of why they are jarring.

There is something wrong with led bulbs but I think author of article misses on why.

I can't explain what's different about them.

The color seems off

My take is they strobe so fast that it's undetectable to the eye but subliminally, this causes them to still feel off.

There is a way to build led bulbs with a resistor so they don't pulsate. For reasons unknown, they don't make them constantly lit. Is it a cost thing?

You're thinking of a capacitor, not a resistor. The varying voltage level of rectified AC causes the flicker, and a capacitor smooths out that varying voltage level to a smooth constant level eliminating the flicker. A resistor just reduces voltage/current, doesn't remedy the cause. There are 3 reasons some manufacturers don't put in capacitors; 1)it adds cost, 2) it takes up space, and 3)it decreases the reliability of the bulb because capacitors are prone to failure. The reason the color seems off is because the LED is deceiving your eyes into thinking you're seeing white, when in reality you are only seeing combined red, green, and blue. The intermediary colors are missing. Natural light is an almost-even distribution of wavelengths across the visible spectrum, LEDs simulates that with (extreme) peaks of narrow bands and the valleys are absent of light. Your eyes are fooled, but your mind knows that part of the data is wrong. Also, to reach equivalent brightness of natural light using only narrow bands, they must increase the intensity of the bands way past what they would normally be in a natural light... meaning that specific narrow bands are way more intense to compensate for the missing parts of the spectrum. In addition to being annoying and looking fake and gay, this is a danger to your eye health because of the blue pigment in LEDs. The blue pigment is the most energetic because the wavelength is shorter, meaning there is more energy than red... this over time damages the cones in your retina irreversibly. All of these headlights, streetlights, and "security" lights the world is embracing are slowly blinding us. I wear blue-blocking polarized sunglasses while driving at night to try and mitigate the danger. In addition, I have a tint-strip on the top of my car's windshield that comes down just enough to reach the horizon of my view, so that things above ground are dimmed to 5% and the road itself is unaffected. This helps a lot with reducing glare from cars and streetlights and lets me see the road better.

LEDs are even more dangerous at night, because your pupils dilate to adjust to darkness, and let more light in, increasing your retinal exposure to hazardous levels of unnatural light.

This is a graph showing the part of the electromagnetic spectrum related to sunlight, highlighting the visible portion, in natural daylight: https://velcdn.azureedge.net/-/media/com/deic/daylight/1-1/fig_1_1_1.jpg?h=783&iar=0&w=1280&cc=grid_6&key=153209092547702

This is just the visible spectrum, daylight: https://velcdn.azureedge.net/-/media/com/deic/daylight/1-1/fig_1_1_2.jpg?h=691&iar=0&w=1280&cc=grid_6&key=153209095371123

This is a halogen incandescent: https://velcdn.azureedge.net/-/media/com/deic/daylight/1-1/fig_1_1_3.jpg?h=691&iar=0&w=1280&cc=grid_6&key=15320909607203

This is fluorescent: https://velcdn.azureedge.net/-/media/com/deic/daylight/1-1/fig_1_1_4.jpg?h=691&iar=0&w=1280&cc=grid_6&key=153209097161261

And this is LED: https://velcdn.azureedge.net/-/media/com/deic/daylight/1-1/fig_1_1_5.jpg?h=691&iar=0&w=1280&cc=grid_6&key=153209097818243

Notice the huge blue spike in the LED compared to natural light.

I encourage everyone to do research on this issue and tell others.

Some other topics to research are: how flashing blue lights increase anxiety (pulsing LEDs anyone?), how blue light disturbs your circadian rhythm, how plant life is affected by artificial light, how artificial light changes animal behavior, how light affects your mental well-being, and studies on the retinal damage caused by the blue spectrum from LED sources.

I could sit here all night and write a book on this particular topic, but I have work in the morning. This is only one of many sections of the vast electromagnetic spectrum I have issues with. "They" are literally trying to make us suffer while they poison us to death.

The modern world is a disgusting abomination, and it just keeps getting worse, seemingly at an exponential rate.

5% lower windshield as in almost black or 5% as in almost not tinted?

This you?

https://pic8.co/sh/oycrrc.jpg

I once made my contractor uninstall every single led recessed can light terminal in a house we built, that they had just spent a day wiring up in the attic. Took them an extra day and I made him pay for it.

He didn't think I was serious.

What part of "No led in this house do you not understand?"

I'm familiar with full spectrum lighting. They do make some fluorescent (and other lights) that emit pretty close to full spectrum. It's gotten so difficult and expensive I'm just happy to find incandescent when I do shop. We do avoid the blue 5k+. They have their uses, just not in my house.

5% as in 95% less light... limo black stuff. That picture is almost me, I don't have the bottom tinted, because that's illegal in my state and they enforce it (unless you're LEO, they are allowed to have full-front windshield tint of any strength). I'm already flirting with a ticket with my top windshield being over the 6-inch limit from the top of the glass. I would really like the bottom strip though.... I was thinking of getting some that is peel-able and stick it on the inside bottom of the glass... so I could remove it if the situation gets sticky. Even the reflection off the road of the overhead LED lights is annoying... more-so when it's wet.

I definitely feel you on interior lighting as well... I moved into an apartment a few years back... it was full of CFL and LED lights.... the very first thing I did before moving in was replace every damn bulb with incandescent. I don't mind paying an extra $50 a year on power for good lighting that isn't hazardous to my health.

LED bulbs simulate sunlight. They are little suns. They disrupt your circadian rhythm. Do not use them.

Best ones I’ve seen. Still prefer incandescent.

Everybody i know who complains about LEDs buys the cheap shit, spend a buck or two on cheap chinese crap and think that you had the best on offer.

Try to find a brand that sources out of korea or taiwan and is not assembled in south asia or china. You want to look on the label for "programmable" only if you're tech savvy and willing to put in the time, or something about blue light being restricted or controlled, failing that you could settle for a warm color tone.

They suck and you hate them because you buy cheap garbage that flickers or shorts out, the blue light is making it hard for you to become restful and is causing eyestrain, or the color pallet of any given room is thrown off by white or cold light, it could also be you have old, shoddy electrical wiring in your house or lamp.

I have old LED running lights in my 27 year old conversion van and not a single one among dozens has ever failed because back then japan or taiwan made the lights and they were wired by americans.


If you pay any attention in setting them up. They run far more efficiently and look as nice or nicer than incandescent bulbs, most of the time. Some things that take unique or purpose built incandescents need them so don't assume I support a ban.

[ - ] AugustineOfHippo2 0 points 2 yearsApr 3, 2023 15:58:05 ago (+0/-0)

Led are hit or miss. Either they ware really good, or just crap. Very little in between.

[ - ] WanderingToast 1 point 2 yearsApr 3, 2023 15:28:30 ago (+1/-0)

Nothing nefarious.

Just the incandescent bulbs are well out of patent and so no ability to compete against China.

The new bulbs all have parts with patents

I've had 11x 10 year light bulbs burn out on me in the past year. They are absolutely pieces of shit

[ - ] MaryXmas 0 points 2 yearsApr 3, 2023 13:17:35 ago (+0/-0)

Welp, I have nearly a lifetime supply of light bulbs for just this reason.

So, how should I heat my “no freeze” closet in Montana????

I have a stand alone closet in my unheated garage in Montana. I insulated the closet and installed a temperature controller. I put items in the closet that should not freeze when I am gone for the winter.

My heat source? Three incandescent light bulbs. Like an incubator for chicken eggs. No, LEDs won’t work. Not enough heat.

[ - ] bobdole9 2 points 2 yearsApr 3, 2023 12:24:54 ago (+2/-0)

Heat lamps exist. Unsure if it will produce too much heat for the area, but they seem to be useful for weak Californians that can't stand weather in the 30s.

[ - ] bobdole9 3 points 2 yearsApr 3, 2023 12:15:33 ago (+4/-1)*

Buy quality bulbs. I've had Feit Enhance bulbs since 2007. The dimmable bulbs do not flicker and you get a closer to true color than other bulbs. The CRI value is how close it is to real sunlight...most bulbs are either 80 or 90, 90 being better.

I've recently bought cheaper LEDs for my basement. They suck - color is off and flicker. When it dies I'll invest in something less shitty.

Edit: I've also had dimmers DOA from the store. Luckily installing multiple of the same switch can verify what's wrong.

Also - daylight is 5000k, the standard incandescent "yellow" is 2700k. Full-blast sunlight is 10,000 lumens per square feet.

[ - ] oyy_veyy_goyy 2 points 2 yearsApr 3, 2023 13:15:20 ago (+2/-0)

This right here. With LED bulbs, you really have to pay attention to the quality, otherwise you will get issues like flickering and shortened lifespans. Unfortunately that does mean you'll have to pony up additional shekels, but hey, you get what you pay for.

[ - ] Prairie 0 points 2 yearsApr 3, 2023 23:51:38 ago (+0/-0)

I've gone through the phases and am pretty satisfied with what I use now (Sylvania reduced eye strain 2700K, unfortunately discontinued it seems, grabbed a few dozen on deep clearance at Walmart a while back). For whatever reason the 60W and 40W ones flicker significantly, whereas the 75W and 100W do not. The 100W also works great with normal lamp dimmer, adjusting to not flicker even when dimmed greatly.

I came across a video where a guy (long-windedly) tests various bulbs, including incandescent (which flickers!) and a CFL with a spectrometer, flicker detector, RF emissions, and dirty power over the AC line. Some good information for people not versed in the differences in LED bulbs. https://yewtu.be/UKOhKmFOjCE

As someone here mentioned a while back, you can use your phone to check for flicker by using manual shutter control and putting it way down (e.g. 1/3200 of a second, with the highest ISO). Lights that flicker will show light and dark bands on screen.

People shouldn't dismiss LED because people stupidly get cheap daylight or cool white 5000K bulbs.

When you say flicker, do you mean like pulsate on off , but hard to detect because going so fast? Or are talking about like an intermittent flicker?

[ - ] bobdole9 1 point 2 yearsApr 4, 2023 17:32:08 ago (+1/-0)

I've dealt with both. Christmas lights do the fast pulse...I will take the light string while on and spin it like a jump rope to check it. Things like undercabinet lighting will do it too - that I can test by moving my hand back and forth; they're shit if I can see "shuttering".

The one in my basement has something going out on it - that's more of a sporadic strobe. Guessing a capacitor is slowly dying.

[ - ] AngryWhiteKeyboardWarrior 1 point 2 yearsApr 3, 2023 12:03:47 ago (+2/-1)

I like the LEDs we have in our house. They are a big improvement over the older types we used to have. Not sure what shit the article writer is using, but ours never flicker or anything.

[ - ] InYourFaceNancyGrace 3 points 2 yearsApr 3, 2023 12:18:50 ago (+3/-0)

We moved into this house 7 years ago, replacing all of the bulbs with "13+ year" LED bulbs at something like 4x the cost of incandescent. I know the flickering they're talking about; it happened with mine before they either died completely, or I just tossed them because I don't want to live in a goddamn rave.

My guess is the diodes on one side of the rectifier go bad. That said, incandescent and fluorescent bulbs don't have that issue (but both have other flaws). LEDs are good, but they have their glaring flaws. They're definitely not "must be legally mandated" good.

I had one blow up in my bedroom. Not a fan of mercury vapor clouds. Been purchasing LEDs since.

[ - ] La_Chalupacabra 1 point 2 yearsApr 3, 2023 17:28:28 ago (+1/-0)

I had one begin flickering on me, and I ignored it while I took a quick shower.
Came back about 15 minutes later to a smoke-filled room and a smoldering bulb base.
I estimate I was only a minute or two from a fire.

Can't stand LED.

Regular bulbs for us. Do I need to start hoarding them?

[ - ] bonghits4jeebus 0 points 2 yearsApr 3, 2023 17:52:14 ago (+0/-0)

They still sell many incandescent bulbs in the decorative section. The decoration is getting the same light you used to. I dunno if OP is saying to change that or what.

They don't want to save the environment, they want to make your life miserable and depressing so the next generation will be too hopeless to rebel.

Put as succinctly as I can, Chinese quality control.

The world de-dollaring might be good us in some ways. There's a chance it might lead to production shifting back onshore. At least I hope so.
