ABSTRACT:
A metal halide lamp includes a cast ceramic reflector almost completely comprised of alumina. A conventional metal halide bulb is positioned within the reflector. A glaze and then a dielectric coating are applied to the inside surface of the reflector, such that appreciable amounts of infrared radiation from the bulb are absorbed into the glaze and ceramic and not reflected into the beam.
