Yellow CFLs

>Asking for objectivity
>For something that is subjective

I mean shit, it's almost like you have different color temperatures for different tasks.

Like I'm not going to light my hospital with goddamn 2700K lights, and i'm not going to try to make a comfy lounge with 6000K lights.

I personally like 4000K for everyday tasks, it doesn't look blue/yellow to me.

I have LED lighting. It works well. Two fixtures are temperature adjustable via wifi; thinking about getting more and doing RGB but that's because I want to make a cyberpunk aesthetic bar.

Daylight CFLs, everything looks like it suppose to be

LED at 2700K for normal rooms and 6500K for bathrooms.

5000K+2700K LED pair looks the best.

I'm a painter and if it isn't perfect northern skylight temperature, I ain't interested.

Nobody on this site understands what that word means; it basically a red flag for idiots at this point.

When will 'hur durr LED is bettur' meme stop?
Whole city changed comfy yellow bulbs to led, now streets are darker and ugly.

Phillips hue wifi bulbs that can be activated via siri, i sit down at my rig with iphone docked and tell siri to activate a scene and then it dims everything in /comfy/ colors to set the mood.

It also is connected to my alarm clock so the light slowly wakes me up instead of a shrill alarm.

its some HAL 9000 shit.

>it's Sup Forums's fault that a government bureaucracy ruined your nostalgia and made your city look like las vegas for poor people

>When will 'hur durr LED is bettur' meme stop?

But LEDs are better than CFL garbage.

CFL

Sup Forums was behind G(n)U24

ended up getting controllable bulbs for me room. it's pretty neat but pricey. wouldn't recommend it unless you want to burn that money.

nice way of changing the temp when getting to sleep, then waking up to a light on alarm.

using 2x 12W LED 1050lm 6500K
works as expected desu senpai

I don't understand, I hate light bulbs because none seem to get good amount of light to not fuck up with eyes.

I keep hearing LED last 20+ years apiece but after converting all of mine they still seem to fuse with fair regularity. Am I just crazy or does anyone experience the same?

oh great, here too
I guess this is /mechanical lights general/ now

god you people are idiots

I use IKEA LEDs. They are cheap and objectively are best in their class.

Metal Halide lamps best lamps

reflect the light off the ceiling or have a diffuser between you and the light.

>When will 'hur durr LED is bettur' meme stop?
When someone invents a light bulb that is more energy efficient than LED that can be mass-produced at a reasonable cost.

Get on it, user.

This.

>en.wikipedia.org/wiki/GU24_lamp_fitting
>Use of the GU24 fitting provides compliance with a 2008 ruling by the California Energy Commission under Title 24 (California Building Standards Code) to require high-efficiency lighting on all residential remodels and new construction. The GU24 fitting maintains the energy efficiency of the light by preventing an occupant from using an incandescent bulb instead of a CFL. Adapters to use incandescent bulbs in a GU24 fitting are illegal in the State of California as they would be a fire hazard in fixtures designed for the lower heat output of a CFL bulb.[1]

What the fuck Sup Forums?

>Whole city changed comfy yellow bulbs to led, now streets are darker and ugly.

Go to you're local city/town hall meeting and complain that you miss the warm color lights. All they have to do is order yellow LED replacements in the future.

>buying overclock version for normal rooms
What are you doing nigger?

I love how these redards try to fight households wasting money on lighting while the state allows 27 water bottling manufacturers to take water from a drought state and sell it to other states.

or you know, the remaining 77% of commercial electrical use.

>LED at 2700K
Enjoy your rentinal degradation from blue light exposure.

GE reveal incandescents. STOP USING LED AND CFL FOR YOUR MAIN LIGHTING IF YOU SIT IN A ROOM ALL DAY they have shit color range and flicker at 60hz and give you headaches

okay got it pal but don't you ever scream at me again or I will end you

But 2700K is on the yellow side of the spectrum

>flicker at 60hz

Who the fuck doesn't use a bridge rectifier to get 120Hz? Even chink shit without a smoothing cap uses full wave rectified input.

I have all three types in my room currently. That way they all blend together and cancel out each others faults.

What flaws do they have?

Incandescent or halogen for reading and working

LED in the kitchen and bathroom etc.

It's a long running joke actually. People have been asking for objective opinions on subjective things explicitly for a long time here on Sup Forums. It's a 'meme' just like "what is the best Y and why is it X?"

Now the typical Facebook/reddit/imgur user like yourself may find it very strange and unfunny to repeat the same joke over and over.
But that's how we were. This place is but a husk of what it used to be of course. Thanks to you.

The thing about LED's, especially LED's with promises of saving energy (which municipal or any government inevitably will go for), is that they dim quickly. Fresh installs may be perfectly fine but after a while you can barely see your hand in front of your face.

Oh and to be clear. Good LED's lose brightness very slowly, so you likely won't notice a difference in that case.

But poor quality LED's lose brightness and simultaneously draw less power. So marketing gets its hands on these facts and put their spin on it.

Which is why packaging must say how long the LED will remain above 70% of their original brightness which is like 13.7~22.8 years (@3hr/day)

>which is like
For some LED's sure. But for the cheap junk your government buys in bulk and puts in the lampposts?
Probably not.

>muh colors
>muh flickering

Read the thread.

I went to frys and got these orange candle like bulbs

Shit is so cash my room looks like a sunset at night I love it

How new are you guys. Seriously, I am legitimately curious.

If you have been here quite a while, how haven't you noticed that people always ask for objective rankings of subjective things. It is a running joke. Did you really not notice this or am I being baited?

>led cheap dog
>same price as old cgl
>says it produces the same amount of light as cfl
>use it, get the shitty light angles room looks dank cause led light angles are shit

>LED's
Apostrophes do not form plurals. The correct phrase is LEDs.

user, you do know orange lets other queers know that you're "open", right?

...

Every autist thinks his opinions are objective truths of the universe.

I want to like LEDs, but:
1. they're usually not strong enough, at most you get like 12W (talking about affordable E27 ones)
2. they have narrow light beams

So I still use CFLs, which are pretty decent overall, if you can deal with the slow startup time.

The retrofits from OSRAM (maybe now distributed by LEDVANCE) and Philips are pretty good, designed to be homogeneous across a wide angular emission, and also for colour-homogeneity. They're usually more expensive than the cheapshit/supermarket LED retrofits; not by much, but you get what you pay for, especially for tasks where actual engineering/optical design is required instead of just slapping LEDs into a housing and calling it a day.

>Buy shitty LEDs
>Surprised that they turn out to be shit
>Swear off LEDs altogether

A few days ago someone posted some French consumer report/test of E27 LEDs and some Philips ones did very poorly, while cheap ones from Ikea did good, for example.
(I also have a cheap-ish Emos LED and it's pretty good from what I can see.)

Just picked up an E27 6W filament type 2700K 810 lm bulb for ~$4. I hope it turns out alright. I'm going to put this in place of my CFL which I hate (weak light, probably the wrong type).

>6W
>810lm

doubt it

Yeah I know. I'll report back with a review in a few hours.

>Grow lights
>Not even full spectrum
Come on user.

There's no way LED dimming is a thing, right?
Big clive would have totally mentioned it if it was...
Anyway, just don't overdrive the things, problem solved.

>LEDs
>Not lighting a room
Come on, this is a single fluorescent light replacement tube.

Main lights: 6500k

Desk lamp / accent lighting: 3500k or lower.

Hungarian scum

Honestly I hate lights. Sunlight is painful to my eyes.

The only lights I use in my NEEThovel are the flashlight on my cellphone when needed and the light on my stove. Other wise I live in complete darkness.

What's that, Iancu? You still have incandescents in your shed? You still can get them because you are not in the EU right?

There are people here who light their homes.
THE VERY PLACES THEY LIVE IN @ over 3000k
With a mere handful of lumens.

>no heat sink
>probably no smoothing capacitor

It's going to be shit.

It's p okay so far. Not vibrating, I like the temperature, could be a bit brighter though. Next time I'm going with a 8 or 10 W model.

>Big clive would have totally mentioned it if it was...

He did

Awox Smartlight Color.

Pretty good, but the new one they released is better in some way.

f.lux + yellow CFLs is comfy at night at the battle station.

LEDs are objectively superior, assuming you don't get no name chink shit with piss poor CRI
Ikea bulbs have a high Cri and are pretty damn affordable

Incandescents are too damn power hungry and CFLs are pure eye cancer

Streetlights however should remain HPS, LEDs destroy night vision

Are you photophobic?

How do you read this thread if you live in darkness?

this

that's a lot of lumens

He uses a nook and his stove light, or by candle

I don't think so. Just photosensitive to sunlight/normal light maybe? Computer and screen light doesn't bother me too badly but I have to have the brightness very low.

But all of those are light sources

try explaining the streetlight thing to normies

Pure bright white LED.

Fuck that fake warm shit.

I use 2700K for my bedside lamps and 5000K for my desk lamp.

Light is light

A warm white is ideal
Also, fuck gu24

Usually those are custom made and good quality.

>Honestly I hate lights. Sunlight is painful to my eyes.
>Just photosensitive to sunlight/normal light maybe?

It's possible that, like me, your pupils just aren't capable of closing down enough to cut out bright light. But I've had other eye problems as well and wouldn't know about it if I hadn't needed to see an ophthalmologist since I was four. Not sure how common it is. For most of my life I've had clip-on sunglasses I would carry with me until I eventually got some transitions lenses a few years ago. Though I still have to use the clip-ons in the car because the transition lenses require UV light to work, and laminate windshields block those wavelengths.

UV light from CFLs fuck up plastic/paint/ink/paper/etc around it. They are the worse lights around.

LEDs on car headlamps piss me off big time.

I use superior graphene bulbs made from the hottest meme material in the scientific meme community.

I live in Seattle and a while ago the city partnered with retailers to sell screw type phillips LED bulbs for about 2.50 a bulb. I bought a 3 dozen and replaced every bulb in my house and still have a bunch left over.

Why?

>businessinsider.com/first-graphene-light-bulb-hits-stores-2015-3
>cleantechnica.com/2015/07/05/graphene-light-bulb-hitting-uk-market-soon/

Where are they?

Wew led...

So according to the consensus, is 2700K the optimal temperature for a living room or a kitchen? And 6000K in a bathroom? What's the reason for that?

I'm moving in a few months and I've been thinking about getting all bulbs from IKEA (for warranty reasons mostly). I kind of like the look of filament type bulbs and the fact that they are made of real glass not some opaque plastic shit. But looks like I will have to settle for the Ledare range.

>and the fact that they are made of real glass not some opaque plastic shit

Yeah but you can abuse the shit out of the plastic ones and they won't break.

>LEDs are objectively superior

Yeah, superior at destroying your retinas
ncbi.nlm.nih.gov/labs/articles/27751961/

Xenon is best.

Yeah but it's not like it's in an industrial environment so it needs to sustain abuse of any kind. I screw it in and it sits peacefully im my ceiling lamp of choice.

Also, logic tells me glass is superior because it has better transparency.

>only cold-white, blue, and green leds
>no warm-white LEDs tested
>omg leds radiate too much blue light!

this is fucking stupid

What does that have to do with glass vs plastic?
You can get diffused glass light bulbs and clear plastic bulbs.

I prefer classic bulbs, everything else is too unnatural to me.

I prefer gas mantle lights, everything else is too unnatural to me.

Funny thing is, the orange/yellow sodium lights were better because they helped preserved night vision and minimised light pollution.

>I screw it in and it sits peacefully in my ceiling lamp of choice

You've never dropped a light bulb before? Especially when replacing an awkward ceiling lamp?

And if it's in the ceiling, you're not going to see it all that much anyway. Decorative glass LED make sense only with tabletop lights.
