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

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

Answer 1

The correct response is:

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

Incandescent light bulbs are less efficient because most of the energy they consume is emitted as heat rather than light. In contrast, LED bulbs convert a higher percentage of the energy they use into visible light, making them more efficient.
