Incandescent light bulbs

Incandescent light bulbs transform heat of the electric chain into light.

The incandescent light bulbs function transforming into light the heatthat the electric chain produces when passing for its filaments.

But 6% of this heat are transformed into visible light.

About 75% of the expended energy it is lost in infra red radiation and 0.25% in ultraviolet.

19% remains are wasted for the environment.
