Light bulbs are technology

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.

>>58568090
Daylight CFLs, everything looks like it suppose to be

>>58568090
LED at 2700K for normal rooms and 6500K for bathrooms.

>>58568090
5000K+2700K LED pair looks the best.

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

>>58568118
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.

>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]

It's a long running joke actually. People have been asking for objective opinions on subjective things explicitly for a long time here on 4chan. 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.

>>58570978
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.

>>58571610
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.

>>58571610

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)

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.

>>58572315
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.

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.

>>58568090
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.

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.

>>58584980
>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.

>>58578972

Xenon is best.

>>58585046
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.

>>58584980

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.

>>58585189
I prefer gas mantle lights, everything else is too unnatural to me.

>>58568445
Funny thing is, the orange/yellow sodium lights were better because they helped preserved night vision and minimised light pollution.

>>58585086
>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.

Because most people don't know the difference between projector and compound headlamps. And anon is angry at he source instead of the type of enclosure and lending.

Anon is also probably young enough that they don't realize most of the lamps that have a high color temp are actually still xenon HID. Keeping in mind that the average car lasts 11 years and LED headlamps have only been in mass market vehicles for a few years. Not to mention they're still an expensive option in most cases.

>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?

Personal preference. Bathrooms (and often kitchens) are very commonly equipped with cooler fluorescent sources. So people are used to it.

I'm actually an architect that works for a lighting design consulting firm. We never change the color temp from either 2700K or 3000K in a residence. The only time I can think that I've specified anything over that in the last few years was a hotel parking lot where ownership wanted to match the neighboring property's 4000K pole mounted area lights. Otherwise we would have kept them 3000K like the rest of the landscape fixtures.

>>58568445
>comfy yellow bulbs

Low pressure sodium lamps really, really suck for color reproduction. They only emit light on a few specific wavelengths bunched closely together. In fact, because of that, you'll have ordinances around observatories that ban any other form of exterior sources because it's easy to filter out those wavelengths and allow the telescope to see through the light pollution. And as >>58585219 notes, warmer sources are generally less disruptive to a person's night vision. They're less disruptive to wildlife as well.

In reality, cities use higher color temperatures because they can get more light out of the diodes. All LEDs start out as a blue diode with a phosphor over it. So the closer to blue, the less phosphor is needed, and the better the efficiency (lumens per watt). Cities are all about squeezing every last drop of budget, so that's what we get. But there's a growing backlash, so hopefully we'll go back down to sub 3000K sources in the future.

my city recently replaced a sodium HP lamp with an LED light. absolutely fucking disgusting.
- the light's horribly cold compared to EVERY other lamp in the area (including CFL)
- the beam is more down directed, resulting in the surrounding area being fucking dim while what's lit being three times as bright as before.
- the lack of a diffuser makes it blinding

That's not even possible unless they have a coating that is eliminating a huge portion of the light output towards the red side of the spectrum.

CFLs being worse doesn't make LED flicker okay. LED bulbs can be made with virtually zero flicker. The only reason it's an issue at all is because of manufacturers cheaping out to save pennies on designs/components.

In the residential realm, lighting typically makes up one of the smallest portions of energy usage, even when full incandescent. Plus, most people tend to be more wasteful by leaving lights and other devices on unnecessarily.

I use the most efficient incandescent lighting possible, and I'm diligent about turning off lights and other things when not in use. I try hard to minimize my usage of resources, and I'm a huge advocate of building things to last and refusing to buy things designed to fail or be thrown away when they don't have to be.

I feel I'm doing my part well without making sacrifices to my light quality. I hope some day to make the move to LED completely, but that day won't come until I'm either satisfied with the offerings or run out of incans and can't buy them any more. Maybe if it comes down to it I'll have to learn how to build my own lights with autism-quality LEDs proper drivers.

It's insignificant when compared to the cost of running a fridge or stove. Especially if you dim them. And some people are willing to pay a few dollars a month extra to have better quality light.

Costco sells LED tube lamps for $30. They are amazing, I bought 4, and hung them in my garage. I have fucking everything lit up now.

Years ago I spend like $120 on a pair of shitty CFL tube things, they converter thingy or whatever its called burned out after 8 months in both. and they flickered like shit.

Comfy light:

Efficient energy use:
LED > CFL > incandescent

So depending on what you want out of those I'd say either LED or incandescent is superior.

If incandescent was a bit more energy efficient and the bulbs lasted longer I would use nothing else.

I used those 1000 lumen Ikea bulbs, I think the new ones are smaller and generate less heat

>>58590713

I'll would be more worried about LEDs as they vent all their heat in the base. Meanwhile, incandescents don't really get all that hot at their base.

>>58591421
No. Go fuck yourself.

>>58591495
>Especially if you dim them
Dimming makes incandescent lamps exponentially less efficient, actually.

Sure, you save some power, but you'd save a lot more power for the same light level by using a lower wattage bulb without dimming.

>>58588304
>In reality, cities use higher color temperatures because they can get more light out of the diodes. All LEDs start out as a blue diode with a phosphor over it. So the closer to blue, the less phosphor is needed, and the better the efficiency (lumens per watt). Cities are all about squeezing every last drop of budget, so that's what we get. But there's a growing backlash, so hopefully we'll go back down to sub 3000K sources in the future.

Then why are 2700K LEDs cheaper than 5000K?

>>58592024
Would spot light bulbs be better?

>>58592603
depends on the dimmer. most have heatsinks that absorbs the extra energy, and the good ones actually decrease the amperage going to the bulb, and are a lot more efficient.

>>58592402
>Meanwhile, incandescents don't really get all that hot at their base.

They get hot as hell like any bulb type if they're installed base-up in a ceiling fixture. Higher wattages especially.

>>58592637

It's not about the dimmer but the watts. Less current -> filament is less hot -> black body spectrum shifts into the inferred.

>>58592637
I wasn't referring to energy losses at the dimmer itself. There might be some losses in the dimmer system, but it's by far a secondary concern when it comes to dimming incandescent lamps, because the majority of efficiency loss is from the incandescent lamp itself burning with a cooler filament temperature.

When you dim an incandescent lamp, you are reducing the filament temperature, which reduces light output AND power consumption. However, it reduces the light output more significantly than the power consumption, because a cooler filament is inherently less efficient. The dimming method doesn't make any difference as far as the incandescent lamp itself is concerned, because the filament responds slowly to fluctuations. In practice with any decent dimming system, the only thing that matters to the incandescent lamp is the average voltage drop across the lamp.

https://en.wikipedia.org/wiki/Lamp_rerating

The formulas described here are a great place to start for anyone interested in predicting how incandescent lamps will behave with modified specifications.

As an example, let's say you have a 100 watt lamp which produces 1600 lumens. 16 lumens per watt means it has a filament temperature of ~2850K. If you use a dimmer to achieve an average voltage drop of 106 volts across the lamp, the filament will have a temperature of ~2700k, a whole ~150K cooler than before. This reduces light output to ~1036 lumens, while consuming 82 watts of power, which means you end up with an efficiency of only ~12.6 lumens per watt instead of the 16 you get with the lamp powered at its design voltage.

In this real world example, instead of dimming the 100 watt lamp, you could instead use a 75 watt, 1100 lumen lamp without a dimmer to get even slightly higher light output with less power usage.

>>58593009
Continued:

The big advantage to the dimming option is that you quadruple the lifespan of the lamp. However, incandescent lamps are cheap to produce and made mostly of abundent and recycleable materials, so it generally makes more sense to treat them as disposable items and prioritize efficiency to save power consumption and just replace the lamps more often. Obvious exceptions to that would be applications where the lamps are difficult to change or serve a critical purpose where failures must be minimized.

>Costco sells LED tube lamps for $30. They are amazing, I bought 4, and hung them in my garage. I have fucking everything lit up now.

Did you rip out the ballast or got tubes that works with T12 magnetic ballasts?

>>58592889
Dimmers aren't giant resistors, they're phase choppers. They use TRIACs which shutoff at the determined voltage each cycle, effectively reducing the mains voltage.

>>58568090
I use soft white for everything, the kind of white that has a somewhat yellow tint to it. I'm not exactly sure of the color temp.

I basically use anything but incandescents. Anybody who still uses that shit is mentally handicapped. I know many families who still use them for every light because "theyre only 60cents a piece haha why waste money??" but then have to replace them every 2-3 months when they all burn out. Not to mention how much money you're wasting because 1 bulb uses 60 whole watts + the heat output is awful.

I am trying to convert to all LED, I'm almost finished (I still use CFLs in some areas), but I will admit that LEDs do have their issues. One pack I bought started flickering every now and then after about a month so I had to replace them, and I can also hear the whine from some of them, so that kinda sucks.

>>58595407
Yeah, they have nice bulbs.
I just wish someone made decent G8 LED bulbs. I had like 6 drops lights that I still have to use expensive as hell incandescent types.

I don't care how energy efficient my bulbs are because the only thing that significantly affects my utility bill is my central air/heating.

I use soft white incandescents for everything. I don't mind spending an extra $50-$100 a month to warm or cool my house during winter or summer, so I sure as hell don't care about spending $10 a month to have soft, warm, comfortable lighting instead of soul crushing harsh blue light that makes me feel like I'm on a factory floor. I like being comfortable at home, I like having the temperature and lighting exactly how I want it.

I feel like a lot of people ITT think that MORE LUMENS=BETTER

I usually only have a floor lamp and the stove light on in my living room/kitchen area, I only really turn on the main overhead lights when I'm cleaning.

Why not use Xenon instead? You could have the same amount of light with a power consumption of roughly 30 watts. Xenon is gas on power, but at roughly 20k V, the light comes from the burning of the gases. It has similar effects in terms of warmness like regular bulbs.

Anon, it's a couple dollars a month extra to keep using some decade-old bulbs I already have. They provide an objectively better quality of light and usability with my home's dimming system at a minimal additional cost. They do their job better than any of the dozen or so LEDs I've tried. I don't doubt the tech will get there, but it isn't good enough yet.

It doesn't matter what it is.
