The reason incandescent light bulbs are considered to be lower efficiency than LED bulbs is primarily related to how they convert energy into light and heat.
The correct answer is:
**a greater percentage of the energy output of the incandescent bulb goes toward heat.**
Incandescent bulbs produce light by heating a filament until it glows, which also generates a significant amount of heat. As a result, most of the energy consumed by incandescent bulbs is wasted as heat rather than being converted into visible light. In contrast, LED bulbs are designed to produce light more efficiently, with a smaller percentage of energy lost as heat, making them much more energy-efficient overall.
