Yeah and fuck fluorescents.

LEDs can only emit one wavelength of color at a time; it's harsh light. They also flicker on/off at 120hz, which is hard to notice but subconsciously can wreck your circadian rhythm. Both of these issues also cause eye strain.

Incandescents put out a broad spectrum of light which is more natural, and while they also adhere to 120hz, the flickering is almost imperceptible even when viewed with high speed cameras; the filaments don't have time to cool off and go dark between cycles.

He's complaining about blue light, it will keep you awake because your circadian rhythm relies on colors of light to help you wake and get tired, the dawn contains a lot of blue light and the day a little less, sunsets go more red and the blue value in natural sunlight stripped down significantly, in part the moon being an almost true white as well is why full moons can keep you up at night they have a much higher blue response curve through our atmosphere.

Look into rayleigh scattering if you want to know why the sky is blue and why the dawn is most blue.

Anyway LED white light bulbs are only possible now because TVs got the cost of blue LEDs down so much through bulk production. fluorescents are worse because their blue values are tied to their gas/plasma and the Affordable ones all have high blue response values.

Cheap LEDs have shorter lifespans or faults and usually a flat or near flat white light response meaning practically equal colors you want a warm light at minimum never buy cool lights, never set devices you use after sundown to cool light and you should probably keep everything in "warm" lighting what is changing between them is the blue light warm is less blue cool is more normal is close to flat white which is still too much blue.

You want yellow to be your highest response curve in your led lights, as to hertz this is how often it's flicking on and off tvs have been doing 60 or below since we switched to leds 15 years ago, higher herz is preferable but your eye nor any domestic animal eye can spot the flicker above 50 hertz, and your eye can't really spot the flicker at 24 either because that's what all movies have been running at since audio tracks were linked to film in the 40s or 50s.

I think somebody in here is attributing an old wives tale about staring at fire and conflating the flicker and not the intensity of the light for what damages your eyes.

Low or just above perceptible flicker (under 25-30, but usually 3-20) can cause brain strain but no reports have ever indicated that effect happens at 60 hertz or above. Light intensity and relative light intensity can damage your vision so turn your tv brightness down and don't stare at light bulbs, use lampshades.

Philips has a very good light bulb but I don't recall the number for it but they also have a dimmer technology under the header "warm glow effect" at home depot and online that warms the color output as you dim the light so if you are a nut about this sort of thing you can set up dimmers with timers on all your lights or lamps and make sure the color tone shifts to help keep your circadian rhythm intact.

But if you want good LEDs which last 10-20x longer than incandescents you have to pay, never cheap out and buy $1-2 dollar LEDs the good ones start at $5 bucks per.

Its frustrating to need to know color/light science to be educated enough to buy a good lightbulb but the cost savings of LED bulbs does make it worth it over incandescents.

There are websites out there with graphs and color response charts for different bulbs maybe start there if you don't want to buy and install dimmers everywhere.

Seriously. You can get LEDs with decent CRI and they're just as good as incandescent bulbs.

You ignore the cost of dev and a bunch of useless circuitry and chemicals, none of which are need for incandescents.

Kill your self with toxic crap, leave the rest of us out of it.

Very interesting. So it seems the internet, or at least chatgpt has been sanitized to only give the current formulation of chlorine, and the reason has something to do with 9-11. In other words it has something to do with the sweeping powers congress gave the deep state after they were manipulated using that terrorist attack.

I remember a long time ago seeing a bleach structural formula that had a chlorine atom surrounded by 4 nitrogen atoms. Knowing that the biggest bombs are based on nitrogen bonds rearranging from single to double and triple bonds that structure would clearly make for a very powerful high explosive. I bet this is why they changed it.
