A light bulb radiates energy in form of electromagnetic waves. Most of them are in the infrared part of the spectrum (heat), some visible light and some in higher regions of the spectrum (ultraviolet), especially bulbs with very high filament temperature (halogen).
Another answer
A light bulb does not "produce" energy it uses electricity or more specifically changes electrical energy to electromagnetic waves in the forms of thermal and light.
Thermal (or heat) waves at invisible infrared frequencies
Light waves at visible frequencies and invisible ultraviolet frequencies
Further note
Electromagnetic radiation that has a wavelength in the range from about 4,000 (violet) to about 7,700 (red) angstroms may be perceived by the normal unaided human eye.
It produces a mechanical energy that makes the?æcircuit flow. When the electrons return to its original energy level, they release the extra energy in the form of photons.?æ
The two forms of energy that a light bulb produces are light energy and heat energy. More efficient bulbs will produce more visible light per watt of power used and less heat.

Both heat and light. These are radiant energy.
A light bulb produces heat and light. A more efficient bulb produces more light and less heat.

Electricity is the source of energy in a light bulb.
A light bulb uses electrical energy, and produces light, as well as heat.
A light bulb IS not a form of energy, it CONVERTS energy. A lightbulb converts electricity into heat and visible light.

actually, the rare-earth phosphors lining the tube.
Compared to other types of light-bulb, energy-saving light bulbs will create less heat. This is because any wasted energy is converted to heat.
Yes, leaving a light bulb will damage the environment because the energy used to light the bulb comes from a coal fired station and whilst the light is on, coal is burnt which releases carbon dioxide into the air which may contribute in global warming.
In a light bulb, electrical energy is transformed into light energy and heat energy.
Electricity is the source of energy in a light bulb.
Most of the energy in a light bulb is heat energy.
A light bulb uses electrical energy, and produces light, as well as heat.
light and heat energy occur in a light bulb when it is turned on.
In a light bulb, electrical energy is transformed into light energy and heat energy.
A light bulb is not an example of electromagnetic energy, but the light which the bulb gives off is an example of electromagnetic energy.
