Question

Why are incandescent light bulbs considered to be lower efficiency than LED bulbs?(1 point)

A smaller percentage of the energy output of the LED bulb goes toward light.

A smaller amount of energy is wasted by the incandescent bulb.

A greater amount of energy is required for the same light output from the LED bulb.

A greater percentage of the energy output of the incandescent bulb goes toward heat.

Answer 1

A greater percentage of the energy output of the incandescent bulb goes toward heat. Incandescent bulbs convert most electrical energy into heat rather than visible light, making them much less efficient than LEDs.
