I’m trying to get you to stop reducing temperature scale to “anything over 60 °C is hot” because it’s not useful: a clearer distinction should be made between something that regularly causes house fires and something I unscrew while it’s on to put under my blanket when my toes are cold. Human perception of temperature (classic 0-100 °F) just does not allow comparing things an order of magnitude higher (in Kelvin ofc). There’s also more to heat, its effects and how it’s perceived than a single measurement of temperature: thermal mass, conductivity, color (exchange via radiation differs between black and white bodies) etc.
Also, it’s indeed ad hominem but you did choose the username yourself.
Literally all I said is large LED arrays get hot. I did not say that there is nothing hotter in the world than LEDs. I didnt say LEDs were the only source of heat in the universe. I said nothing, but that LED arrays don’t run cold as the original commenter thought.
You’re the one thats spent this entire time trying to “Well ackshually…” and wring your hands in desperate argument to prove a point that no one was making or even talking about.
You’re still being reductive. An indicator LED can work without any part of it more than 10 °C above ambient temperature. No incandescent light bulb can achieve this.
And yes, there are indeed lighting systems that use many low-power LED chips spread over a large area, none of which get hot even by human standards. These cost a lot of money but last extremely long.

Try so hard to desperately disprove my point, and you fail so catastrophically that you fall into the low hanging trap that is my username.
Congrats for playing yourself.

And you want to call me an idiot for it.
