Abstract: A halogen incandescent lamp is operated in convection-free conditions. Light efficiencies of about 15-20 lm/w may thus be achieved with a service life of about 2,000 hours. The important parameters are the size of the bulb, the size of the luminous element and the properties of the filling gas.
