Best Answer

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.

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.
