Energy efficient light bulbs

Abstract

BFC stands for Compact Fluorescent Lamp. These lamps are commonly called light bulbs. The only real difference between a traditional fluorescent tube and a BFC is its size, which makes it point the light emitting source, decreasing its efficiency in lighting. The first device ancestor of the fluorescent lamp was the Geissler tube, producing a bluish light thanks to a noble gas. The main advantage of BFC versus an incandescent lamp is energy efficient. Roughly estimated a savings of 25% for a similar light. The main disadvantage is that the brightness of the lamp depends crucially on the emitting surface, ie the cylinder surface illuminated.
