No, a light bulb is not an energy source. It converts electrical energy into light energy. The energy source for a light bulb is the electricity that powers it.
When energy runs through a light bulb, it produces light energy. This is a form of electromagnetic energy that is visible to our eyes.
A light bulb typically uses electrical energy to produce light. The electrical energy is converted into heat and light energy by the filament inside the bulb.
A light bulb uses electricity as its source of energy.A light bulb to uses electrical energy which is supplied to a resistor that gives off heat as well as light. The resistor is a thin coiled piece of wire made of Tungsten because it has the highest melting point of any metal.For more information see the answer to the Related question shown below.
A light bulb gives off electromagnetic energy in the form of visible light.
incandescent
When the bulb is lit it uses energy. When there is no bulb, no energy is used even if it is switched on.
This depends on how long it is being used. The 60 Watt bulb consumes 2.6667 times the power of an 18 Watt bulb, but energy equals power times time. There is also an amount of 'hidden' energy: the energy to manufacture and transport the bulb. This depends on how long it is being used.

Uses more energy and power.
Uses more energy and power.
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.)

A light bulb uses energy. It uses electricity.
No, the wattage of a bulb does not determine the amount of energy it gives off. Wattage measures the amount of power the bulb consumes, not the amount of light or energy it emits. The brightness of a bulb is more related to its lumens output, which is a measure of visible light.

A light bulb typically uses electrical energy to produce light. The electrical energy is converted into heat and light energy by the filament inside the bulb.
The power rating for a light bulb (like "40 W") tells how much electrical power the light bulb uses. All of the power used by the bulb is either converted into light or heat. In an incandescent bulb, most of the energy becomes heat. In a fluorescent bulb, more of it becomes light.
