Which light bulb is known for consuming more energy and converting most of it to heat?

The incandescent light bulb is known for consuming more energy and converting a significant portion of that energy into heat rather than light. This is due to its design, which typically involves heating a tungsten filament until it glows, producing light as a byproduct of the heat generated. Approximately 90% of the energy consumed by an incandescent bulb is lost as heat, with only about 10% actually converted into visible light. This inefficiency is the primary reason incandescent bulbs have largely been replaced by more energy-efficient alternatives such as LED and compact fluorescent bulbs, which convert a higher ratio of energy into light rather than heat.
