In contrast a typical led might produce15 visible light and 85 heat.
Led light bulbs no heat.
Especially with high power leds it is essential to remove this heat through efficient thermal management.
Instead of heating up the bulb to produce light the led uses semiconductors that bond atoms with surrounding diodes to create power.
An incandescent light bulb creates light by warming up the filament that throws off light.
