Safe LED lighting in 2018?

it is not the BLUE LIGHT itself retard, it is the blue spectre waves LED emits.

And there is no "beliefs", it is confirmed scientific study

dumb retard

Can some faggot explain why in the hell someone would think blue light is bad?

BECAUSE IT LOOKS BAD

Can some faggot read the research or fuck off?

Can some faggot just explain it instead of expecting me to read pages of bullshit?

Sunlight is considered to be an ethalon of the light (color index/intensity/spectre richness).

LED emitters have a gap in the 480 nm wave range and CRAPLOAD of blue in 460nm range.
Because of the first, the eye's pupils do not behave correctly like they do under the sun. As you know, it shrinks in the light and expands in the dark. Under white LED light (that passes through protective luminophore coating) it behaves weirdly and erratic and mostly expanded way more than it should under such intensity of he light.
This leads to the problem when to much light in the blue spectre reaches eye's retina (read aboe: led emitters have way more blue than the sun) and blue light is what really damages retina.

Now, imagine what happens when over the years the luminophore coating degrades? LED already have a high eye hazard but the worse the coating the higher the danger. Especially over the years because it is cummulative damage

>we shone a blue laser at a petridish full of retinal cells
>it damaged the cells
>therefore blue light is harmful
>please buy our blue light blocking glasses so you can use your computer without damaging your eyes

You are a low information low iq brainlet who fell for a paid marketing scam with a bogus "study" meant specifically to legitimize a snakeoil product using "science".

>being this retarded
>failing to read basic brainlet-level study how eye retina works

>and blue light is what really damages retina.
No, it doesn't.

for you

as a side note when looking at this picture, remember: human eyes are most sensitive to /green/

yes it does, read:
ncbi.nlm.nih.gov/pmc/articles/PMC2885915/

When blue spectre light intensity is high, melanopsin M1 Brn3b+ forms a signal that reduces the pupil's size ths protecting retina from the blue light.
However, because in the LED spectre there is a gap, M1 Brn3b+, as observed, does not work correctly and either sends weaker signal or does not send one at all

You can buy LED lightbulbs with "warm" light now, they don't glare, aren't a harsh white light and they're the closest I've found to old filament bulbs.

warm light is just cosmetic, spectre barely changes, it is not really about the color the coating gives afterwards, it is about what diode emites

>EU bans everything but LED
T-thanks

Higher frequency damages eyes

Blue light does not damage your retina, you retard.

It depends on frequency and intensity

blue light won't do anything to your eyes but ultraviolet will, which is why sunglasses exist

ultraviolet is not blue

What you see is what it emits. Unless you're talking about parts of the spectrum literally imperceptible to the human eye, you're more than free to use a glass prism.

...retard
LED barely have any UV and thus it never was the point of the topic.
UV damages a lot of things, but retina can be damaged by the light in other spectra too

Bulb or not, it will need protection against the elements, unless you want naked leads constantly exposed and at the risk of shorting.

Because people don't understand evolution.

They think going outside is unnatural and only hiding in their basements under a red light protects them from the dangers of the world.

The most widespread protection is against ultraviolet radiation, which can cause short-term and long-term ocular problems such as photokeratitis, snow blindness, cataracts, pterygium, and various forms of eye cancer.[16] Medical experts advise the public on the importance of wearing sunglasses to protect the eyes from UV;[16] for adequate protection, experts recommend sunglasses that reflect or filter out 99% or more of UVA and UVB light, with wavelengths up to 400 nm. Sunglasses that meet this requirement are often labeled as "UV400". This is slightly more protection than the widely used standard of the European Union (see below), which requires that 95% of the radiation up to only 380 nm must be reflected or filtered out.[17] Sunglasses are not sufficient to protect the eyes against permanent harm from looking directly at the Sun, even during a solar eclipse. Special eyewear known as solar viewers are required for direct viewing of the sun. This type of eyewear can filter out UV radiation harmful to the eyes.[18]

More recently, high-energy visible light (HEV) has been implicated as a cause of age-related macular degeneration;[19] before, debates had already existed as to whether "blue blocking" or amber tinted lenses may have a protective effect.[20] Some manufacturers already design glasses to block blue light; the insurance company Suva, which covers most Swiss employees, asked eye experts around Charlotte Remé (ETH Zürich) to develop norms for blue blocking, leading to a recommended minimum of 95% of the blue light.[17][21] Sunglasses are especially important for children, as their ocular lenses are thought to transmit far more HEV light than adults (lenses "yellow" with age).

>Not using 2700K T12 tubes.

>"According to the SCENIHR Opinion on artificial light1
: "blue radiation directly from bright
cold white light sources in proximity of the workers eyes (e.g. task lights) or strong
projectors (floodlights, accentuation and scenic lighting, etc.), or reflected may represent
a risk for retinal damage; the blue light component from cold white reading lights may
perturb circadian rhythm of the user; a child’s crystalline lens is more transparent to
short wavelengths than that of an adult, making children more sensitive to blue light
effects on the retina.""

Old familiar form factor.
People still have loads of light fixtures designed for 230/110V AC bulbs.

In the future we'll have LED's in all sorts of shapes powered through USB-C.

>USB-C
lmao, what a fucking retard

It's bad for your sleep and by extension for your health in general. Somehow blue light reduces sleepiness, which immediately results in localized insomnia.

You're the retard, retard.
KYS

basically, avoid the cold harsh lights
Why anyone would use them for anything is beyond me

u wot?

That explains why my LEDs light makes white objects look purple.

Edison screws are literally the simplest fixture there is, why the fuck would you want a considerably more fragile and more complicated connector designed for hot-plugging peripherals to be used for a permanent fixture in a possibly harsher environment?

Blue light helps regulate your sleep cycle.
Blocking blue light all day long will CAUSE insomnia.

For best sleep cycle you should be exposed to blue light from just after sunrise to just before sunset.
ie: just as you would if you lived outside.
I can change the color temperature of my LED lights to do just that.

>why the fuck would you want DC power for LED's?
KILL YOURSELF NOW!!

Am I the only one that likes 5500K light?

LEDs produce only 1 wavelength of light, you can't make them white naturally. Do they make UV LEDs and use photon step-down converter chemical which transforms UV into visible light. Output spectrum is not perfect and neither is UV absorption.

What's stopping you from sending DC over the two bar buses on the Edison screw?

'white' LEDs are a bit of a hack, they're actually just blue LEDs with a special phosphor coating which gives off a yellow glow under blue light (blue + yellow = white),

Nobody can possibly be this retarded.

There are many ways of getting DC power. LED worth their shit have a rectifier in the circuitry. Newer fixtures are thought of that also take the philosophy of the Edison screw of "simple and sturdy" but have a transformer/rectifier. No USB-C needed.

Cheap LED's will often have a very poor spectrum which makes object an unnatural color, yes.

But there are higher quality LED's available that do a really good job, you just have to look for them and probably spend a little more.

you mean "driver"?

Any frequency can damage you if it has enough intensity

A blue laser will fuck up your eyes

A blue lightbulb won't

Blue wavelengths don't damage your eyes, you are evolved to see blue you retard

Don't buy chink shit. I have LED lights and I'm not seeing anythong purple. Things are a little bit duller than actual sunlight but it's nowhere near as bad as the shit that was fluorescent lamps.

>transformer/rectifier.

Which gets hot and eventually causes the LED to fail.

It's also a huge waste of energy and resources using shitloads of shitty Chinese rectifiers and transformers into nearly every device.
A DC circuit is a much better idea, and since we now have a standard charging power in the form of USB-C we might as well use that instead of having dozens of different plugs and adapters.

>Blue wavelengths don't damage your eyes, you are evolved to see blue

You're also evolved to go outside and deal with a thousand times more UV light from sunlight than you will ever get from a weak ass LED.

stopntrying to justify your stupid shit. AC is required for distribution, you will need an AC to DC converter and you don't beed an overly complicated plug just to connect to it. Newer sockets are there that allows you to fix a converter somewhere so you can screw an LED bulb that doesn't have that shit

>complicated plug
It's a cheap mass produced plug, nothing complicated about it.
Way simpler than using converters as you suggest.

My lampshade has trouble letting go of that old familiar form factor, since it attaches directly to the bulb.

philips suck

Normal people don't like everything becoming piss colored.

You were wrong in 2015 and you're wrong now.

Because code monkeys saw a paper where albino rats with dilated pupils got eye damage after prolonged exposure and think seeing anything blue will now make them blind.

>hal.sorbonne-universite.fr/hal-01383394/file/Krigel_Light-induced.pdf
>Interestingly, as compared to albino rats, no significant morphological retinal damage was observed in pigmented animals under these lighting conditions.
>Many factors influence retinal exposure and retinal toxicity, including retinal pigment epithelium pigmentation, pupil diameter, geometry of the face and the nature of the light radiations, including its spectrum, its intensity, the exposure sequence and timing of exposure (Youssef et al., 2011, Hunter et al., 2012). Age, lens color (increasing yellow pigment with aging), stress-induced steroids, pre-existing retinal pathology also influence light sensitivity. Extrapolation of animal experiments are challenging and particularly, rats that do not have a macula and therefore do not recapitulate human retina characteristics.

Retinal is a chemical, not a cell.

>retinal (vitamin A) + blue light -> toxic poison that kills any cell
>retinal (vitamin A) + blue light + alpha tocoferol (vitamin E) -> safe
>old people have less alpha tocoferol in their eyes
>they age

The solution is to find a way to get more alpha tocoferol in the eyes of old people.

>it is not the BLUE LIGHT itself retard, it is the blue spectre waves LED emits.

Which daylight has more of.

>And there is no "beliefs", it is confirmed scientific study

You don't understand what beliefs are nor science.

That's not how color temperature works.

White light at any color temperature will look perfectly normal once your brain has adjusted.
For example: everything doesn't look blue when it's overcast (6500K), nor does everything look red under incandescent lighting (2700K).
The only thing that looks off is any light source that doesn't match the color temperature of the rest of the lights.

Nobody uses UV LEDs for white LED lights. They have shitty efficiency compared to blue LEDs.

The green phosphor break down from high heat. Your chick shit leds overdrive their led chips causing the led to prematurely die and the chips to bake in their own heat.

2700K always look yellow.

>speaking out of your ass

That paper has nothing to do with blue leds/light. Fuck off troll.

you're a fucking idiot

No one ever said it has. The paper was about melanopsin and why is it important

So after oodles of niggerization by the horsecock association, there's no actual evidence that blue light is bad?

They just hate the RW&B
