Thread 106578701

(((they))) took this from you

>>106578701 (OP)
200 lm/W would have required a significant compromise in color rendering to achieve. Or they were just overdriving the diodes which would reduce their useful life.

>>106578701 (OP)
>dubai
I don't want it.

>>106578701 (OP)
use case?

>>106578751
if you only knew how bad things really are

>>106578751
they are significantly underdriving the diodes to get that efficiency, thats why they need 12 of them for only 600 lumens

>>106578791
>dubai
the guys who use this lamp probably have shat in the mouths of all your female family members (unless they're ugly)

>>106578807
Overpriced burger/coffee place

>>106578701 (OP)
They also took Tesla's wireless electricity inventions

>>106579145
they are

How do would someone obtain and use them in the US?

>>106579219
OP here, they actually sell them as "ultraefficient"
not sure if they are nearly as underpowered but efficiency numbers are similar

And? I can get 1600 lumen 95+ CRI bulbs that can be fine tuned to whatever color temp I want for only $15 each.

>>106578701 (OP)
>Warm white
Isn't the real Dubai lamp always cold white because Arabs love the tacky look?
I also assume it doesn't have English on it and West-Arabic numerals?

>>106579266
The point is they're more efficient and should last crazy long because they run much cooler.
It's a bit nonsense because normal LED's are already plenty efficient and long lasting, but I think it's more the principle that they could be even better if they didn't skimp on the number of LED's per bulb.

>>106578701 (OP)
Incandescent or it's nigger.

>>106579336
>normal LED's are already plenty efficient and long lasting
LEDs last a long time, but get dimmer over time. Sure it will last 30 years, but it will be barely usable after 5
The Dubai light NEVER gets dimmer because it is not severly overvolted like other LED bulbs
Dubai basically told the light bulb companies to fuck off and make ir right or they won't be making any bulbs in Dubai
Now ever bulb Dubai buys is permanent
It will never die
Capitalists are seething about it

>>106579367
why not both

>>106578701 (OP)
Just get one of those edison meme bulbs.

>>106579336
I know what it is, and I don't give a shit since it's only 80CRI, non-dimmable, and locked to 3000K or 6500K

Then why is the L70 value half that of an equivalent lamp? >>106579408

>>106579408
redpill me on CRI

>>106579496
Dubai lamps are somewhat outdated, the lifetime limitation is likely driver or capacitor related.
Philips Ultra efficient is newer with a 50k lifetime.

All bulbs kinda suck really still. Horticulture fixtures are 50K hours until L90, lifetime is basically indefinite

>>106579564
It can be easily gamed by bumping up specific color values emitted by the phosphor. You can have decent color rendering at 80 CRI, or absolute dogshit rendering at the same value. TM-30 is the new standard but isn't as widely used yet.
Here's an easy to understand explanation.
https://www.dmflighting.com/tm-30-simplified/

All LEDs are shit for ambient lighting, everywhere, forever
No matter how you cope with low wattage, or color wavelength, you will never get around the flickering issue which is present in every single LED ever made because they fundamentally do not emit light with burning metal like the Sun, they are a demonic mockery of the Sun which is divine perfection

>>106580231
It's actually solved, but the big consumer brands are indeed run by satanic assclowns who don't care about quality.

>>106580254
it was actually solved by not being schizophrenic

>>106580231
what the fuck are you talking about?
You stare directly at a goddamn screen all day.

>>106578791
It's called a Dubai lamp because Dubai realized light bulb companies were scamming people with higher power use bulbs that burn out quicker, to use less LEDs in each. So instead of listening to the (((reasons))) this was necessary they told the companies fuck you, make it properly or you can't sell it here.

>>106580423
its called the dubai lamp because the government held a gun to the companies head and made them do something different to what consumers actually want

now people are forced to pay more money for something they don't want

other companies see this sovereign risk and are less likely to invest in dubai, destroying any perceived economic benefit from the regulation

>>106580441
dubai lamps are in such demand people fly to dubai to buy them and take home

>>106580448
they are not in demand at all

i use incandescent and halogen
you are paying for cucked inferior light that daamges your retinas. it's the equivalent of watching youtube on 480p and no hdr but for your eyes irl

>>106579367
Based as fuck.
There are literally no good reasons to use LEDs except in a commercial application to light a very large indoor space without windows.
For home users, incandescent lights are more than good enough.

>>106580496
LE bulbs do not damage your retinas

>>106579266
are those lightbulbs running some kind of esp32 or something?

LABUBU DUBAI CHOCOLATE LAMP

Each adult human now has a spoonful of microplastics in their brain.

Anedotally, I've had LED bulbs last shorter than fluoresents that came before. Phillps and Osram btw

>>106578701 (OP)
They're basically the same as their "Ultra Efficient" range.

>>106580530
I'm running the equivalent of 600W of incandescents in a single room right now and it's still only barely bright enough. Even if you don't pay for your own electricity, incandescents get way too hot for any reasonable light level.

>>106581636
wtf
are you a potted plant, anon?

>>106580231
This is the same argument that audiophools tend to give as to why digital media will never be as good as analog.

Meanwhile, the reality is that incandescent bulbs oscillate (not strobe, but still) at mains frequency, while quality LEDs are electronically driven at frequencies that are way higher than that and are well beyond perception limits. It's the same shit with digital audio - you can crank the sample rate to the point where it is for all intents and purposes indistinguishable from a smooth analog curve.

>t. someone who can actually see the flicker of sodium lamps and certain LEDs.

All the bulbs in my house look like that, are you not allowed to have them or something?

>>106581636
try painting your walls and ceiling in a colour other than black

>>106581655
that's a nice bulb

>>106581642
Do you ever go outdoors? I'm only in normal office lighting range, not even overcast day outdoor lighting tier. Home lightning standards are way too low. It's the future, you don't have to sit in semi-darkness like a medieval peasant any more.

Walls are already white, carpet is beige.

>>106580231
>flickering issue
LED lamps with linear regulators (like the Dubai lamps) have zero flicker. Incandescent lamps have visible flicker when run on AC.

>>106581690
Mini display port is the worst interface for lighting

>>106581680
this is bait, right?
also you dont express luminosity in watts, but in lumens

>>106581636
>I'm running the equivalent of 600W of incandescents in a single room right now and it's still only barely bright enough
let me guess, you have this type of spotlights shining through keyholes in the ceiling

>>106581706
I mentioned the power in watts because it all ends up as heat. I'm running 44W of LED lighting. 44W isn't so bad. But if I used incandescents it would take 600W, which is like running a space heater all day.
>>106581711
Philips Ultra Efficients on a chandelier type fixture.

>>106581704
all digital ports are ass. the DVI to VGA converter is the only way to achieve full color rendering, but the problem is the cards that come with DVI these days only output like 120 lumens

>>106581727
something must be fucky wucky somewhere
i used 600w in a fucking growbox
and worked with 200w halogens

whats the area of your room?
is it square?

>>106581727
>>106581757
>somthing weird
after second thought, i think its your maths
iirc the equivalent of a 60w incadescent is ~17w in LED
so if youre running 44, you would need ~ 160w in incandescent

>>106581757
Roughly square, medium size. I just have higher standards than you. It's only like 300 lux at my desk (edge of the room), it's not even all that bright.

>>106581770
>I just have higher standards than you
maybe check you math standards too

>>106581769
>iirc the equivalent of a 60w incadescent is ~17w in LED
Modern LEDs are a lot more efficient than that. Philips Ultra Efficient, which is basically an updated version of the Dubai lamp, is 210l/W. Their 60W equivalent runs at 4W.

none of these bulbs produces deep reds, so they're worthless

>>106581791
is it what youre running?
>>106581770
>I just have higher standards than you.
i think you might have nyctalopia instead

>>106581205
Yea, they obviously have a microcontroller.
High cri ledvance i took apart has a bk7231n(risc 120mhz, 2mb flash, 256kib ram, wifi 4, bluetooth le 5.2) which is smaller and probably cheaper when bought at scale.
I've seen esp8266 used in some Chinese light switches but never esp32

>>106581829
>High cri ledvance i took apart has a bk7231n(risc 120mhz, 2mb flash, 256kib ram, wifi 4, bluetooth le 5.2) which is smaller and probably cheaper when bought at scale.
what the complete fuck
theres more in a modern lightbulb that sat in the apollo guidance computer

why?

>>106581812
9210 lumens from 6x Philips Ultra Efficient 100W equivalents. This is not excessive. Normal offices are lit to around this level. Even before LED lighting, offices had lots of big fluorescent tubes. Outdoor lighting is much brighter. You don't have to accept the low standards of the incandescent era when bright lighting would make the room too hot.

>>106581838
cheaper to use such a chip than design one with just exactly what you need for the smart features

>>106581844
its not a matter of stadnards
its a matter of necessity
which i dont have

you must be fucking blind anon
conversely i have excellent night vision
so you might be legit nyctalope

>>106581855
>smart features
ah, ok
i thought the tech was superfluous

i mean, it completely fucking is
but not from the standpoint of customers wanting a certain feature

>>106581869
yeah it's to have all these you can do, and probably more with some other apps

>>106581862
It's a matter of enjoyment not necessity. As luxuries go, moderately bright indoor lighting is a cheap one.

>>106581886
>have one controller per lightbulb instead of one controller for the room
>buy a new controller each time you change the lightbulb
even if i wanted these features its an inferior solution

but not when youre a skill-less consumer who values convenience over anything else
normNIGGERS exist to be abused.
it should become legal for tech people to just beat up random passer-bys in the street

>>106581887
i wouldnt even notice it
and like i said, i worked with halogens
i worked in places way brighter than even your current setting bc construction, and plastering, then painting.
you use powerful halogens during the process to make any defect much more visible

>>106579111
No, they are driving it normally. It's other lamps that overvolt the diodes, so they burn out faster and you can buy a new lightbulb. Not much business in it for multinational companies if a bulb lasts forever.

>>106579145
To be fair if I was as rich and powerful as a dubai sheik, I'd probably piss in the mouth of women too. Best of all it would be a portable solution.

>>106580441
>the government held a gun to the companies head and made them do something different to what consumers actually want

Other way around, they held a gun to the company head and told them to make something that's actually good for the consumers: a lamp that isn't artificially broken so you have to buy new ones much more often than you otherwise should.

>>106578701 (OP)
so what light bulb should i get instead then

>>106581757
I have a 3x5m room and a single 200W halogen stick makes it look like the sun is still up. I actually had a lot of problems trying to find a LED equivalent a few years ago. You can get COB LED today that can equal it, but I had to make do with one of these ugly shits.

trying to find a G9 led bulb that fits in my reading lamp is also really fucking annoying, every led bulb is 3x as long as a halogen one.

>>106578701 (OP)
Don't these things have ultra garbage power factors because they use capacitive droppers?

>my entire total electricity bill, which includes PC and an oven and a bunch of old halogen lamps, is $20 a month
>I had a LED lamp fail exactly once in my life
>but you can improoooooooooooooooooove
Are you niggers retarded? I literally don't care if I need to replace my lightbulbs five times or two times in my life, shit is cheap anyway, and most likely I'll change the light setup anyway before any lightbulb fails. Like, I have an entire box of still working halogens and LEDs because I replaced much of that with Hue because colors. I really don't care that these old lightbulbs still have 10 years of potential lifespan.

Also, I don't care about lightbulbs lasting 30 years if I'll move to a different house in 10 years anyway and I'll need to redo the lighting anyway.

Again, I don't care how much energy it consumes, normal non-Dubai lighbulbs are already efficient enough.

>>106582379
>$20 a month
Clearly you aren't paying 0.2€/kWh like most French people are. The worst thing is that Kraut delusions are mostly to blame for this stupid situation.

>>106582379

>>106582386
>my broke-ass country's high energy prices is the fault of another country
nigger your entire power grid will be toast within 10 years and your government has zero ability to replace all your power plants with new ones
you're going to switch to renewables purely because you can't fucking afford nuclear because your retarded government gave half the country to rich corpos and the other half to retired old fucks and (you) are the one paying all of it. fuck you

>>106582343
Good LED lamps don't use capacitative droppers, but the power factor is still usually low. I just tested one of my Philips Ultra Efficient lamps on a cheap power meter (no traceable calibration but seems accurate enough to me) and got 0.55 power factor, which is about what I'd except. It's irrelevant for home use where you only pay for real power and the wiring is a lot bigger than it needs to be for these kinds of loads.

>>106582271
consumers know what is good for them, not big daddy government

>>106581642
He's a weed, who gained sentience.

>>106582470
I know that I'm paying for real power, but still, it's not good for the grid. The ones that use linear regulators are usually a bit better than the ones that use capacitive droppers, but really, the only way to get a good power factor is to use an SMPS, and these days, only powerful bulbs use these.

>>106582601
>it's not good for the grid
who the fuck cares

>>106578751
This is standard now. But why is Dubai 60W only 600 lumen?

>>106582394
>>106582386
Ok I just checked.

My actual electricity bill is €40 a month. The reason why I didn't know the actual number is that I literally don't care, because whether it's €20 or €40 or whatever it's all same shit more or less.

I have been using such a color led lamp as that anon for 5 years now. In the same time I would have had to switch a normal light bulb 4 to 5 times

Tbh I struggle finding LEDs and screens with 0 flicker... im insanely sensitive to flicker and it just wrecks my eyes. OLED screens on phones are problematic as well... ironically my Quest 3 which flickers like hell (checked via camera) doesnt bother me all that much... I guess there is a sweet spot in pwm frequency for me

>>106582257
Source on this degeneracy?

>>106582806
great news, the latest iphone will have the ability to disable pwm flicker

>>106582605
dubai lamp runs on twice as much leds for same lumen

>>106582548
Wrong. Consumers are too dumb to know what's good for them. Corporations herd consumers to inferior products. Corporations are literal tard wranglers.

>>106582873
nope, i know what i want better than someone else

>>106582605
>But why is Dubai 60W only 600 lumen?

Because they don't overkike the led voltages to the point that it shortens their life expectancy. As a result they are not as bright for the same amount of filaments/leds inside, but last far longer.

>>106578701 (OP)
But it's LED. Those lights will prematurely age you, flicker even though you can't see it your nervous system is affected, and cause many other health issues. Switched every light to Chromalux incandescent because they are healthy. Don't be the LED guy.

>>106579367
>>106580530
Incandescent lights are better for the environment.
It's simpler to manufacture, less shit that can't be recycled, and if it could it's which very bad chemical reactions.

>>106582958
>prematurely age you
Assuming you're talking about blue light, most LEDs have lower proportion than sunlight.
>flicker
Get one that doesn't, like in OP pic.
>Incandescent lights are better for the environment.
Maybe if you live in France where they have nuclear power, or Canada where they have hydro. Even if you ignore CO2, burning coal emits a shitload of toxic chemicals.

>>106578701 (OP)
they don't want you to know you could even slash that power usage per lumen by a factor of 3 if you only used green light

>>106583376
i've actually read that it has greenish tint

About 2 and half years.

>>106584372
How are their operating temps in comparison with regular leds? I've had a shitton of them die cause of that and I end up having to strip the malfunctioning leds to keep the rest of the lamp going.

>>106584420
>having to
*wanting to

>>106584420
Noticeable cooler. I scanned one with an IR thermometer on maximum temperature logging mode and the hottest point I found was 17C above ambient. Not sure exactly where this is because it's too bright to read the IR thermometer while I'm scanning it. Probably when I'm aiming it at the controller board through the glass. The glass envelope itself feels barely warm.

>>106578791
The government of Dubai told Phillips they had to make a non shit led and in return they'd have a monopoly. They use less energy, last much longer and are brighter than the equivalent bulbs in other countries. They cost more though.

>>106582605
8 led 4w 840 lumens: 0.5 W 105 lumen per led

>>106580441
>made them do something different to what consumers actually want
Consumers don't want a slightly more expensive bulb that lasts way longer and consumes less power? Because I sure do, but the fucking companies will not sell them to me because then I won't buy another bulb from them for years.

>>106585824
You can just make one yourself with a normal bulb and dimmer. A bulb at perceptual 50% dim is operating at like 1/3 stock power. Finding bulbs that don't flicker like mad under dimming is the real trick.

>>106578701 (OP)
E27 needs to die. this connector maybe made sense 100 years ago when bulbs needed 100W and they were too retarded to manufacture a more compact connector, but it makes no sense in the age of the LED.

>>106585882
there's other connectors

>>106585824
You can easily buy them. Philips Ultra Efficient is even more efficient than their Dubai lamp.

>>106585962
isnt that one with really visible greenish hue?
my plan is to add capacitors as clives videos to regular already decent led lamps
https://youtu.be/ISTB0ThzhOY

>>106578701 (OP)
>(((they))) took this from you
no, they didn't. You could have petitioned your government to mandate efficient LED lights but you didn't

>>106586317
i also want to make a lamp with these leds

>>106586317
>visible greenish hue?
It's subtly greenish and only 80 CRI. I don't care about color accuracy and I don't notice it.
>clives videos
Big Clive has other videos on LED lamp modding. The ones with linear regulators are easiest and unlike the capacitative dropper type they don't flicker (although they sometimes make annoying buzzing noises). They often have two current sense resistors in parallel and if one is removed (Big Clive cuts them with cheap side cutters) it lowers the brightness. It's possible to achieve Dubai-tier efficiency without any green tint.

>>106578701 (OP)

It needs that storage, ram, and processing power to support the BT and WiFi stacks and the HTTP server. Maybe there is some crypto on there too for HTTPS. The actual control code takes up maybe 1% of the resources since all it's doing is configuring a few HW PWMs.

We had a Osram cob in my mom's old floor light.
It began flickering after a year of moderate usage at low dim power.
She returned it to the Obi (Germanys home depot equivalent) and got her money back.
Then we went for a Philips from Amazon which we returned also because it had shit color temperature. (Way too cool)
Finally found a "Müller Licht" one that had a nice temperature and has outlived the Osram by now for half the price.
Thanks for attending my Ted talk.
