DRL lamps

Arc mercury lamps of a high pressure (DRL) are used in systems of lighting where application of the light sources with small geometrical sizes possessing high is required

light return and long service life. It defines wide use them for lighting of streets, open spaces, floor spaces, there where great demands are not placed on a color rendition. Lamps are characterized by high light return and long service life. The combination of reliability and usability of this group of lamps provides the potential of use them and in the future.

Lamps of DRL are operated in alternating current mains with a frequency of 50 Hz by a voltage of 220 V, with puskoreguliruyushchy devices (PRA) corresponding to lamp power.

Arc mercury lamps of a high pressure like DRV it is sources of the mixed light. Are used

for illumination of park zones, open spaces, pedestrian zones, and also in life, garages. They are the universal mercury gas - discharge lamps which are not demanding the external puskoreguliruyushchy device, the combining high efficiency and long service life.

Are used for direct replacement of glow lamps which provides economy of the electric power.

Example of designation: DRL 250 (8) - 1: DRL – arc mercury with a phosphor; 250 – power, W; (8) – radiation share in red area of a range, % . DRV – arc mercury tungsten.
