Fluorescent lamp — gas discharge light source in which visible light is emitted mainly by the phosphor, which, in turn, glows under the ultraviolet radiation of the discharge; the discharge also emits visible light, but to a much lesser extent. Luminous efficacy of a fluorescent lamp is several times greater than incandescent lamps of similar power. The lifetime of fluorescent lamps can exceed 20 times the life of incandescent lamps while ensuring sufficient quality of power supply, ballast, and compliance with restrictions on the number of on / off.
