Incandescent light bulbs are considered to be lower efficiency than LED bulbs primarily because:
**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, a process that is inherently inefficient as a significant portion of the energy is converted to heat rather than visible light. In contrast, LED bulbs convert electrical energy directly into light with far less energy wasted as heat, making them much more efficient in terms of light output per watt of energy consumed.
