I asked him “what color were the clouds back then?” and he said they were white. I asked him what happens if I take an orange light and light up something that’s white with it. He ignored me. He went on about how everyone in his age group remembers the Sun being orange, and by me questioning him, I’m calling him and all his peers liars and I’m stupid because I’m younger than him and vaccinated.
But the sun is hot. You can feel the heat radiating from it.
LEDs are not hot - that’s pretty much the main reason that they’re energy efficient, they don’t waste energy as heat.
It’s not suddenly gotten colder, so if they did switch to LEDs, then they’re also artificially compensating for the heat. Which would completely defeat the purpose of switching (presumably from an incandescent bulb) to LEDs.
Also, I’m super intrigued about who is supposedly behind this sun-bulb maintenance, and more interestingly, what could possibly be powering it
Someones never accidentally touched an LED array.
I can guarantee you an LED array as big as the sun would generate enormous amounts of heat.and would need massive amounts of cooling.
LED chips can’t get above 150 °C or they fail. So high-power LED lights need appropriate cooling. And the heatsink is big and thermally conductive, making it feel hotter to the touch than it is (it delivers more heat to your finger over time). Meanwhile, the glass of some bulbs can exceed 300 °C but cools down to safe levels in a minute (or less if you touch it with something) because it’s thin.
Also, 150 °C (420 K) objects do radiate heat as black-body radiation but not that much, also it’s far-IR so only detectable with thermal cameras. Meanwhile, a light bulb’s filament is 2700 K (3000 K in halogen ones) and the Sun’s surface is 6000 K, and both produce copious amounts of near-IR light that largely contributes to the heat felt on one’s skin when illuminated (although the visible light does too).
So yes, LEDs are hot.
That’s fair - my experience with handling them basically stops at individual LEDs in electronics and domestic LED lightbulbs.
Have you touched strong incandescent lights?
Sure LED arrays are hot, but cooler than old lights
They also add a radiator to keep the charade
