If you live in Dubai, you can have even less.

Bulbs aren't mant to be used bare.
You're supposed to either use them in a frosted fixture or aimed at a wall/ceiling in a fixture that blocks direct sight.

Which brings me to the point that bulbs are deprecated and should be replaced with panels.

>>109705293
They just drive the LED's at a lower voltage.
Meaning the production cost is about doulble, but on the other hand they also last many times longer.
>>
>>109705293
>Or lamps supposed to be this efficient without jewish trickery?
Basically yes. Conversely to incandescent bulbs, where their efficiency increases with power, LEDs are most efficient when barely any current is run through them. So, 1000 low-power LEDs run at 1A will produce vastly more light than a single high-power LED 1A. Those Dubai lamps are shifted towards the larger array end of the spectrum by a factor of like 2-3, so they'll produce as much light with half the power that Jewish bulbs require, and the LED filaments will probably last something like 5x-10x as long.
That said, the shitty "cost-optimized" power delivery circuitry will probably fail long before the LEDs themselves do, like all LED lamps.

Probably, yes.
But by requiring less power the power circuity could also be made to last several times longer than less efficient bulbs.

how does /g/ read that is that a 227 lamp

>>109705334
warm ultra efficient leds are greenish and you can basically look at them directly without flinching
there's a reason none of those ultra efficient leds have any sort of CRI rating on them

That depends on the lumens

Watts good enough for Edison is good enough for me.

>>109705293
LEDs are more efficient when they run cold.
Most LED lights cheap out on the number of chips absolutely grill them to within an inch of their life for maximum light output. That's also why they often fail early, despite LEDs having claimed lifespans of 20+ years.
Dubai chose to exercise their influence/money to strongarm manufacturers into making actually good lamps for their new construction.

>Bulbs aren't mant to be used bare.
Says who?
>should be replaced with panels
You mean the ones where you have to throw out the whole hardwired fixture when it fails after a few years? How about no.
Unless there's a new alternative socket standard that's as widespread and easy to use as the Edison socket, it's not happening.

IIRC those Dubai lamps have some duplicate circuits so they could continue working even after some of them fail.

Ultra-efficient LED bulbs suck because they use a very simple driver circuit, and because the LED string drops almost all the input voltage, any change in the line voltage ends up being visible in the light output. For example, if my GPU is running hard on a shared circuit with these bulbs, you will see them flickering. It's fucking annoying.
>>
>>109709477
Anon I think you should be worrying if a load as small as a GPU causes enough voltage drop to be visible in the lights. I would understand if it's some 2-3kW space heater or something but a GPU is what, 600W max if you have the hungriest piece of shit out there?
