Abstract

A reflector lamp may be made with a reflector and base holding a hermeticy sealed bulb. The bulb encloses a filling and a light source, the light source being a high voltage or medium voltage light source in which an operating voltage of at least 80 volts is present. The reflector consists of a basic body with a reflector contour and a neck part attached to a rear portion of the basic body, and a base which is joined to the neck part and which has at least two metallic contact pins with cylindrical seals on an end farthest from the bulb. A current feeder system makes an electrical lead available for use by the light source. The base is formed completely from the same material as the neck part and as an integral part directly on the neck part of the reflector.
