Has lighting technology reached perfection?

Well if he wasn't such a lazy fuck he would have created another one and we'd have light across the entire disc all the time, can't blame us for compensating for the lack of intelligent design.

Whatever happened to the '50s idea of ambient light? The idea was that all building surfaces would glow to light up an area without shadows or glare.
Imagine a room where the ceiling glowed brightly enough to enable reading but could be dimmed for, say, videos.
The source of the light was originally electroluminescence, but now it would probably be LEDs.

Cree's are 90, some of Feit's are 90 too

Filament lamps have bad UGR, CRI/GAI, poor efficacy and low lifespan. Conventional chip/cob leds are superior in every way.

Remote phosphor

dimmable LEDs are very expensive but can last 20+ years

This has to be a troll post of some kind

Wat?
It is not cheap (shitton of led strips or expensive lenses/diffusers or large drop celling height), not efficient due to light losses in diffuser, expensive no service and it must be installed in a construction phase not afterwards.

incandescent bulbs with really thick filaments that require a shitload of energy and last for a literal century from the 1920s were perfection

Not until they have a near limitless lifespan and waste no energy on anything other than light.

Generally means "less like the visible portion of the sunlight spectrum".

>Filament lamps have bad UGR, CRI, poor efficacy and low lifespan

No, you can get 90 CRI filament bulbs with just as good or better lumens/watt than other led bulbs. They sell frosted filament lights if you don't want sharp bright lines just like incandescence lights had. As for lifespan, it's quoted lower on the box as a guesstimate but actual tests show they hold up just fine.

Leds suffer from 3 issues.

1. Bluelight which can damage your eyes because the pupil can't detect in to reduce size to prevent photon damage.

2. PWM causes a strobe like effect that makes you light headed and motion sick.

3. the AC/DC converter creates a low frequency humming.

Until them filament is superior reading light while leds are nice for outdoors or 24/7 ambience lighting with filter and diffuser to save power and cost of replacement.

It's not good quality light for your health though.

What the fuck are you thinking?

>1. Bluelight which can damage your eyes because the pupil can't detect in to reduce size to prevent photon damage.

Stop repeating that bullshit. It's not true.

It's like you never looked at a CRT.

incandescents can last a couple of centuries if you dim them. Whats your point, again?

>Stop repeating that bullshit. >It's not true.
It's not bullshit and I'm a EE so I'm not "reading bullshit"
Look at how light is produced with LED it's a spark gap ie PLASMA which is blue light just like the sun is (ultra)voilet light
Both are dangerious and both don't retract to prevent photonic damage.
Light from a filament is actually just from extremely high resistance heated material from the electrons flowing constantly and is a yellow/orange light which is in the visible spectrum and considered a natural type light

>It's like you never looked at a CRT.
Exactly those make can make you sick for extended periods too.

>3. the AC/DC converter creates a low frequency humming.

This is true too.
leds can only run off DC and require a AC/DC converter if it's running in a home AC bulb outlet (which is inside the bulb ceramic screw part which is why those still get hot even though the led itself and plastic is useally cool.)

>It's not bullshit and I'm a EE so I'm not "reading bullshit"

Philips already has 'em. Calls the series 'Warm Glow'.

they're pretty and no less efficient.

>no less efficient.
They barely illuminate anything. So they're only used as decoration instead of actual illumination? Sounds like hipster nonsense

its like, they invented something new, LED, that had (surprisingly) none of the disadvantages of old lighting - was efficient, could take any form or shape, didn't need a filament or an expensive and fragile glass manle, etc.

Naturally, having acheived all this progress at a stroke, next logical step was to revert ti into SOS at the earliest possible opportunity. Thus, Tesla design owes more to the horse-drawn carriage than any logical modern transport design, and thus, we now have 'filament bulb' LED lamps.

because he didn't make it possible for light to penetrate windowless walls :DDDD

>not having transparent aluminum walls
Stop not living in the future

>They barely illuminate anything. So they're only used as decoration instead of actual illumination? Sounds like hipster nonsense
they're not all low power. Some are used for accent lighting at 2200K and just a few watts. But you can get them at any light output/color temp you want.

Same reason sub 5000K lights exist, people are weird and illogical.

>sub 5000K
Having very warm illumination can be useful for some places. But at least they actually illuminate the place. The led filament decoration lights barely light up.

So they're night lights.

Everyone on Jow Forums thinks they're a professional photographer/videographer for whom the color rendering index of a light bulb actually matters.

It matters for your mood and eyes not getting tired

And was determined inconclusive, from what I can see.

Since I actually cite sources, here's a paper that suggests you can't really tell what the CRI of a light source is from looking at a scene and even LED lights with terrible CRI can appear to produce good color. cool.conservation-us.org/byorg/us-doe/color_rendering_index.pdf

No fucking reason to use these over regular LEDs for general lighting.
I can get a dollar tree LED bulb that flickers less than these filament bulbs

Who puts windows in a home theater room?

Be aware filament bulbs sometimes have more flicker, because some skip having a power supply and use the LEDs for rectification.

Don't you get way more blue light any time you go outside? I can't even drive on a cloudy day without sunglasses.

Your CFLs use the same kind of phosphorescent material as LEDs. They both hit glowy white shit with ultraviolet. You can make your lighting less harsh by having none of it direct, only reflected off matte surfaces.

>actually make uv light that fucks shit up

It does significantly lower your risk. All cruciferous vegetables do. I usually eat a pound a day because I like them so much.

>No fucking reason to use these over regular LEDs for general lighting.

They have much better light distribution around the bulb's equator vs regular bulbs that send most of it to the northern hemisphere.

>I can get a dollar tree LED bulb that flickers less than these filament bulbs

Flicker is determined by the power supply and there are good filament bulbs with constant current drivers. See

>use the LEDs for rectification

No, they always use at least a diode and usually a full bridge rectifier. LEDs can't handle high reverse biases. What they skimp out on are smoothing capacitors.

Yes.

No.

The first does not follow from the second.

White LEDs are ultraviolet LEDs with white phosphor. An RGB setup has too poor a CRI for general lighting.

The way the bible describes how this universe was created is wrong.
So either the god that did the bible is lying thru it, or the bible does not represent an existing god.

Most blue LEDs are like that too. Direct blue LEDs were very brief. If you put a sticky note over one for a few months, it will turn white in that spot.

this shit is as bad or worse than audiophiles
99% of people buy a light and are satisfied because it's no longer dark
the other 1% are people who put "luminiferous design enthusiast" on their resume

>White LEDs are ultraviolet LEDs with white phosphor.
No. Blue LEDs with a yellow phosphor.

Depends on your climate.

wat

cold peeps like "warm" yellow, warm peeps like "cold" white, so that's what stores carry.

99.999% of all white LED are blue LEDs. The only exception is Yuji that makes violet based 98+cri LEDs.

UV LEDs are still at a premium and quite rare. Even some "black light" LEDs in stores are really just 405nm violet leds (though they still cause things to fluoresce) and not sub400nm actual UV.

why don t you plug in your computer to the sun then ?

Jesus christ can everyone in this thread stop sperging and tell me what lights I should be using

5778K sunlight LEDs

Get some kind of LED bulb.

has nothing to do with cold vs warm. The only difference is the proportion of blue to yellow. Same blue pump, same yellow phosphor. Read the data sheets.

the cheapest ones they sell and a good return policy
no one actually notices notices any of the shit in this thread unless they make a point of obsessing over it.
light + dark area = illuminated

>99.999% of all white LED are blue LEDs. The only exception is Yuji that makes violet based 98+cri LEDs.
True, and they're both half as efficient and get the high CRI as kind of a cheat (moving the 'hump' of the pump color into a region the classic CRI charts don't check for).

The hump isn't a problem so much as the missing deep red spectrum and to a lesser extent the missing violet and intermediate blue spectrum.
