Kinda crazy to think about considering that LEDs are so efficient that they typically do not produce any significant heat at the use cases we're used to.

The part that emmits the light doesn't produce heat radiation like a incondecent bulb, but the circuits driving them do.

[–] [email protected] 4 points 4 months ago

That's not exactly true. The LED itself also emits heat. In most cases, this is more than the driver.

LED bulbs for vehicles also usually have at least a heat sink. Some of them even have a fan or other active cooling.

I've only seen it in enthusiast level flashlights lol.

I have a few that will hurt your hand after a bit, and most have a heat cutoff sensor.
