ABSTRACT OF THE DISCLOSURE A low pressure sodium vapor lamp including a sodium vapor discharge tube within an outer envelope. The outer envelope is par- tially coated by a light reflector defining a light transmission a- perture for desired directional light output. The outer envelope is additionally coated with an infrared reflective coating defining a heat transmission aperture at a location separate from the light transmission aperture. The heat transmission aperture acts as a heat sink. The area of the inner discharge tube corresponding to the heat transmission aperture thus becomes the coolest portion of the dis- charge tube, the "cold spot" of the lamp where excess sodium is con- densed.
