Incandescent light bulbs are not energy efficient, as much of the energy they use is converted into heat rather than light. Only about 10% of the energy they consume is actually turned into light.
Around 90% of the energy consumed by an incandescent light bulb is converted to thermal energy, with only around 10% converted to visible light. This inefficiency is one of the main reasons why incandescent bulbs have been largely replaced by more energy-efficient alternatives.
Incandescent lights also produce heat energy as a byproduct of their operation. This heat energy is often an inefficient use of the electricity powering the light bulb.
Incandescent lights produce heat energy in addition to light energy. This heat energy is a byproduct of the light-producing process and is why incandescent lights can become hot to the touch when operating.
Only about 10% of the electrical energy used to light an incandescent bulb is converted into light energy. The rest is mostly given off as heat.
Aerobic Energy Pathway
Efficiency of a respiration pathway refers to the amount of energy produced by the pathway relative to the amount of energy input. A highly efficient pathway will produce more ATP (energy) per unit of substrate consumed, resulting in greater energy yield for the organism.

Most of the energy of an incandescent bulb is given off as heat rather than light. Incandescent bulbs are not very energy efficient compared to other types of lighting, as they convert a large portion of electrical energy into heat instead of light.
