post everything about lighting technology, light bulbs

light bulb types:
-incandescent
-halogen
-LED
-arc

Many (((governments))) ban sale of incandescent, even though they offer highest color quality.

how the FUCK to buy fucking LIGHTING (bulbs) that don't fry your eyes?
typical bulb is 600lm which is insane
I want lighting for night
the lowest I found are 15-25W incadescent/halogen bulbs which are 100-200lm
there are still very powerful and not suitable to keep them on for long time
I want some minimum ambient light, how to achieve that?

I thought halogen was even better color quality? I don't like LED light because it glares like sun off car windows in front of me.

Nanonymous No.7343 [D] >>7344
>ban sale of incandescent
It causes fires. That's the reason.
Incandescent is still used in some photography equipments, though.
>highest color quality
Yes, they are "black bodies" (just like the sun), but it has downsides too:
- Color temperature unbalanced
- High energy consumption

>>7340
For indoor/house, you should try 6500K lights (yellowish). This might even help your melatonin levels.

LED is the way to go, but if you want quality you should get a high CRI (Color Rendering Index) LED (>95), since normal LED light has a green/blue cast:

that is a voltage regulator?

>I thought halogen was even better color quality?
not sure if better is possible, both incandescent and halogen have 100% CRI
but halogen can have higher color temperature (colder) than traditional incandescent, so maybe that's preferable

>>7343
>- High energy consumption
not a problem for low intensity light or small rooms

>For indoor/house, you should try 6500K lights (yellowish). This might even help your melatonin levels.
I don't care about color temperature much, I just want low intensity light, even weakest LED have 250lm or more

Yes, a rheostat. I forgot the pic name wouldn't transfer on post. Then you can make incandescents as dim as you like.

If you have one, sure. If you have a big house and need 20+ of them, then it might make a big impact on your energy costs.
>I don't care about color temperature much
Well, you probably should. This is relevant for sleep quality.
>never seen them, at any shop
Normally you buy those online. Example: https://www.yujiintl.com/

The "color quality" meme is bullshit.
LEDs can be ANY color you want them to be, including "Incandescent" (which is 2700K).
Just get some cheap ass 2700k LED bulbs and you are good to go.
The "non-dimmable" kind are usually cheaper.

>I want some minimum ambient light, how to achieve that?
You probably want a dimming switch, and some dimmable LEDs. Or maybe a really dim LED with very few lumens.

>LMAAAAOOO WHY NOT JUST GET A INCANDESCENT OR HALOGEN, THEY R CHEEPER

More bullshit, LEDs use less energy (they have made measuring bulbs in watts useless, use lumens like a real man), which costs less on your electric bill, and live forever. Most Halogens and Incandescent use way more energy, produce heat (LEDs don't), and fail much sooner.

>THE GLOW IN THE DARK LEDS CAUSE CANCER
This is true only if you use so much blue light you don't get any sleep (cities or business signs will use white LEDs which are terrible and produce lots of blue light), and because you don't sleep you get a higher risk of cancer.
This is why you use blue light filters on computers/devices.

>CFLs bro, nobody mentioned those
CFLs are just worse LEDs.
They produce heat, use more energy, and usually have a "warm up" period as well.
Still better than Halogen or Incandescent though.

LEDs are the best followed by, CFLs, Halogens and finally Incandescents.

Red or green light is best for sleeping, as it's only one band of light devoid of blue. Some animals can't even see them.

it's not a meme and you are a retard
you post image with color temperature. it has nothing to do with color quality
https://en.wikipedia.org/wiki/Color_rendering_index
incandescent and halogen have 100% CRI, typical LED 80% (but there are special LEDs that are better)
there is also some other metric of color quality which is better than CRI metric

>You probably want a dimming switch, and some dimmable LEDs. Or maybe a really dim LED with very few lumens.
how to get whatever of those

>LEDs use less energy which costs less on your electric bill
but they cost few times more so you will need years to save any money

>and live forever
sure, LED shill. I don't know any electrical device that lives forever

>produce heat (LEDs don't)
LEDs do produce heat, althrough few times less

>This is why you use blue light filters on computers/devices.
why can't devices just not produce so much of it?
instead of filters I would prefer just to dim the screen, it wil lower the blue light and other light

>CFLs are just worse LEDs.
>Still better than Halogen or Incandescent though.
CFLs are not just worse LEDs. they give horrible unnatural light, they destroy your eyes, they contain mercury which poisons the environment and also poisons you if you damage the bulb
CFLs are the worst type of lighting and should be illegal.

>LEDs are the best followed by, CFLs, Halogens and finally Incandescents.
as I explained, CFLs are the worst, produce the worst light, are the most toxic. this is more important than 1$ or less of electricity per month

When most people think "color quality" they think like >>7341 by saying
>I don't like LED light because it glares like sun off car windows in front of me.

Which is basically saying "I don't like this particular type of LED bulb".
The CRI is not mentioned or referenced in >>7379.

>how to get whatever of those
Try a major hardware store probably, or maybe online. They look like pic related.

>sure, LED shill. I don't know any electrical device that lives forever
Figure of speech, retard.

>LEDs do produce heat
In shit lamps, yes.

>why can't devices just not produce so much of it?
Ask the hardware companies, I mean color e-ink does exist.

>CFLs toxic and environment
Only for retards that throw them in the trash or for retards that fuck up and break them AND don't use proper safety.
They are recyclable.

>this is more important than 1$ or less of electricity per month
correct

Why would you care enough to say LEDs are the best? They aren't that good.

>muh cheap long lasting expensive bulb

Incadescent is cheap enough and offers best nostalgia for money, plus L.E.D bulbs are factually more gay than regular incandescent ones.

>"OOh there's this new bulb out that you positively must buy because it's so fantastic, it's called the L.E.D light bulb and it does things in lumens and doesn't produce heat which is bad because it causes a fire (you've never experienced a fire from your incadescent bulbs but they happen all the time believe me) and it has a variety of color temperatures and I'm going to marry one because-"

Look, we get it, do you prefer the bayonet cap or the screw?

Bayonet is superior. Screw is a poor attempt at making a "threaded joint", which is very low quality and screams of cheap ch*nkoro engineering, because no one seriously makes threads out of fucking sheet metal.
Bayonet basically just pushes in and turns to lock, and transfers electricity through two dedicated contacts. Bayonet style sockets will never wear out with bulb changes, but screw type ones always get bent or mangled because they are made of thin sheet metal.

It is perfectly reasonable and not even as bright as sunlight.
>I want lighting for night
They are all for night roflmao.
When going to sleep, why wouldn't you just shut all the lights and curtain all the street light instead? Absolute (well, close to) darkness is cozy as fuark.

Replying to your question though, there are probably specialized solutions for that shit, including aforementioned dimmers, which are kinda eh for your purpose IMO though.

it is extremely bright. I don't care about sunlight, implying I ever leave my prison

>When going to sleep, why wouldn't you just shut all the lights and curtain all the street light instead? Absolute (well, close to) darkness is cozy as fuark.
it wasn't about sleep. when sleep I also prefer zero light. it's about using computer or doing other things after sun is not present

Any light will flicker (50-60Hz), unless you use direct-current incandescent lights.

LEDs need DC, so you can probably find fancier ones with a full wave rectifier in them.

Better than Incandescent, except for photography apparently.

>Incadescent is cheap enough and offers best nostalgia for money

>nostalgia
What does that even mean?
If you just want the color tone of Incandescent get 2700k LEDs.

>cheaper
Not really, they use more energy (and thus more $$$ unless you use solar panels or something) and unless they are really high quality ones (Made in Hungary or something) they fail way sooner.

They also make heat.
Yes, LEDs can make heat also, (in shitty lamps) but it's a lot less. Get good lamps if you can afford them.
>lol who cares it won't cause a fire
Didn't even think of that (fire hazard).
The problem with them generating heat is it requires your air conditioner to then work harder during summer.
Or it can just be really uncomfortable if you don't have one or it sucks.
In winter I suppose this wouldn't be problem, but it's still energy being wasted on something a light bulb doesn't need to be doing.
