How are lights glowing at very hot temperatures like 5000K and 6500K kept relatively cool to touch?

Question

Also, why do their components and things in close proximity not melt or catch fire?

Answer 1

Incandescent lights can very much burn you. They also don’t get above 2700K at the filament – tungsten has a melting point you know.

Cold colored lights generate light using methods other than just heating themselves to glow. LEDs exploit electrons falling to a lower energy state giving off photons, those tube lights excite gases using high voltage, etc.
