In an incandescent light bulb, electrical energy is converted into heat energy due to resistance in the filament, and the heat energy is then transformed into light energy. Overall, the energy transformation process involves electrical energy being converted into both heat and light energy.
The energy present in a lighted lamp is primarily electrical energy, which is converted into light and heat energy. The electrical energy is used to power the lamp's filament, which emits light and produces heat when it becomes incandescent.
Light bulb: Electrical energy is converted into light and heat energy. Electric heater: Electrical energy is converted into heat energy. Television: Electrical energy is converted into light and sound energy. Electric fan: Electrical energy is converted into mechanical and sound energy. Computer: Electrical energy is converted into heat and sound energy, as well as processing and display energy.
Electrical energy from a light bulb is converted into light and heat energy. The electrical energy is transformed into light energy that illuminates the surroundings, and a lesser amount is converted into heat energy that is dispersed into the environment.
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.

In a LED, electrical energy is converted directly into light energy, resulting in a decrease in electrical energy and an increase in light energy. This process is much more efficient than traditional incandescent bulbs, which waste energy as heat.

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.
In a lamp, electrical energy is converted into heat due to resistance in the filament of an incandescent bulb, and into light due to the radiation emitted by the heated filament or by the excitation of gases in a fluorescent or LED bulb.
The job of a light bulb is to convert electrical energy into visible light energy. (Not ALL of the electrical energy a bulb uses is converted to light energy. Their efficiency is quite low. An incandescent light bulb is more efficient as a heater than as a source of visible light. Fortunately, our eyes are very sensitive.)
Electric energy is converted into light and heat energy in an incandescent lamp. The electric current passing through the filament of the lamp heats it up, causing it to emit light as well as heat.
