Great post!

Instead, we get Obama's LED garbage.
They're generally capable of producing higher luminosity, but a significantly lower quality of light.
PWM, as implemented by most companies, is destroying our eyes.

"It's time to retire old-fashioned inefficient technologies from the last century. LEDs are the future of lighting. Wasteful throwbacks like this need to removed and updated - forcefully, if necessary (judging by the old white man in the photo)."

It's so simple to write like woketards. You just disengage higher-level thinking and the pretty but stupid sounding words just flow out so easily.

The stress on the light filament happens during the turning on. Pretty much every incandescent that is of standard quality can do the same if you just leave it on.

That's brilliant! Just leave all the lights on, all the time and you'll save a ton of money on light bulbs. Thanks, niggerfaggot. I owe you a solid.

Yes, if WEF plans are going right, we will have limitless cheap solar/win energy to power all the electric cars and lights we could ever want.

But in a 15min city there is no need for a car and your sleeping pod only needs a 0.6 Watt light.

So either way all your problems are solved, be happy.

Plus, the filament in the old-ass bulb is very thick

It's called "Planned Obsolescence“. It's a common business practice and is openly discussed during the design process in many industries.

My dad is an engineering/electrical nerd. He makes his own lightbulbs. He’s been using the same bulbs since I was a kid. When he sells a house, he takes his bulbs with him. My friends used to think it was weird that my dad had a laboratory over the garage. Free light bulbs for life, he keeps me supplied. Not sure they’re as energy efficient as LED’s, but they last forever.

If every light lasted 120+ years, the light manufacturers would go out of business. You wouldn't want to put all of GE out on the streets would you goy? Thomas Edison was a business man first and an inventor second. He understood the need for repeat business. That's why he invented the electric chair and used it to kill elephants. What do you need an eternal light bulb for anyway? Planning on passing the torch to your grandkids? Oy vey, that's antisemitism.

Replacement bulbs are far from being their main source of income, stop being such a stupid fag.

He also understood the need of stealing shit from pesky inventors who would never let his repeated business happen.

Well I want see how fit and glowing you are after making it 120 years.

It's the standard retarded "this is proof things could last indefinitely" and also draw a shit ton of power for the tiny bit of light it puts out. It's basically a heater that also happens to put out a little bit of visible light.

[ - ] HeavyBrain 0 points 2.2 yearsApr 13, 2023 15:29:51 ago (+0/-0)

You do realize that 120 years ago it was a normal glowing light bulb that produced enouugh light that people bothered to put it there and then over the years got weaker but is still functioning unlike "modern" ones that won't do shit after a set amount of hours.

There is always room for improvement, I also like that LED lights dont waste 90% of energy on heat when I look at my electric bill.

The argument its about that shit shouldn't break 5 hours after the warranty is over and as we see it doesn't have to.

Sure it gets dim over time, and when its too dark for you change the bulb, but you should have the decison.

Thx for shedding some light on the matter.

Not like its some 100w globe illuminating a whole room, the element barely glows.

Filament.

That thing glows more like a heater than light globe hence element

[ - ] localsal 1 point 2.2 yearsApr 13, 2023 15:02:56 ago (+1/-0)

That's exactly the thing. This light bulb is run much lower than the rated specs, making it last longer. I don't think it is as much the "high quality" manufacturing that makes it last so long, compared to the limited stress put on it.

For example, if a 100watt incandescent light bulb has an operating temperature of 300c, and can last 1000 hours at that temperature, in a reduced power setting, if the temperature only gets to 50c, the life will be exponentially longer.

They are under-powering it intentionally to extend the life. It runs on DC.

[ - ] Prairie 0 points 2.2 yearsApr 14, 2023 06:20:05 ago (+0/-0)

It runs on DC.

Interesting side-note, people who swear by (normal AC) incandescent lights don't realize they flicker more than high-quality LED bulbs. And if you wanted a DC supply for normal incandescents, you'd be wasting even more energy on heat from the power supply.

You can make a plain old tungsten filament bulb do this by sticking it on a dimmer. One quick trick is to put the lamp in series with a diode, cuts the power by half, reduces the light by a bit more than half, and extends the life by a factor of fifty.

Having lots of weak lights is actually a really nice look but hugely a PITA to install, obviously.

They're already making LEDs that "burn out".

There are some very old computer parts with still-functioning LEDs.

[ - ] NoRefunds 2 points 2.2 yearsApr 14, 2023 02:17:24 ago (+2/-0)

I had 12x 10 year lightbulbs burn out in 8 months.

Some brands I've used are garbage, e.g. EarthTronics' EarthBulb. All failed within a year. I guess they mean it literally, you'll be putting them back in the earth.

[ - ] Prairie 1 point 2.2 yearsApr 13, 2023 13:56:33 ago (+1/-0)

They're making LED bulbs that are cheap because people don't want to pay $10 a bulb for high quality LEDs and sufficient heat sinking in a fixture that has proper air flow.

Meanwhile that tiny LED that puts out a fraction of a what is running cool and naturally lasts for decades. You can actually do this with LED bulbs by dimming them so that they run cool, you'll just need to have more of them to put out sufficient light.

[ - ] herbert_west 1 point 2.2 yearsApr 14, 2023 04:55:25 ago (+1/-0)

I pay around $10 for OSRAM LED bulbs and they only last for a year or two.

[ - ] Prairie 0 points 2.2 yearsApr 14, 2023 06:17:16 ago (+0/-0)

Do they have free ventilation? Do they run continuously all day?

[ - ] herbert_west 1 point 2.2 yearsApr 14, 2023 07:02:05 ago (+1/-0)

I use them at home and they are turned on max. 4-5 hours per day inside one of those panels people normally have on the ceiling. Obviously they are overheating.

LEDs don't burn out, but their light changes tone over time much like this light bulb here.

[ - ] oyveyo 1 point 2.2 yearsApr 13, 2023 20:46:53 ago (+1/-0)

The bulb was originally installed when power was distributed by DC, Tesla's AC came later. They are still running it on DC, but they have lowered the voltage to extend the life. The color it puts out is due to under-powering it.

[ - ] bonghits4jeebus 0 points 2.2 yearsApr 13, 2023 22:47:04 ago (+0/-0)

I guess I got downvoted for commenting on the bulb above. According to manufacturers of LEDs, the lifespan is over when the gamut of the device has shifted a certain amount. They could last longer, but they no longer look good.

Unfortunately, I read, manufacturer descriptions have not yet been standardized making it difficult for consumers to tell the features/properties of a bulb.

[ - ] Prairie 0 points 2.2 yearsApr 14, 2023 06:16:30 ago (+0/-0)

They do burn out when they run hot. One thing that happens in semiconductors at high temperatures is migration of the metals. The atoms literally diffuse.
