Collision

High Pressure Mercury Vapour Lamps for General Lighting Purposes,The fact that the high pressure mercury vapour lamp could be introduced successfully as a practical light source, is due to the favourable spectral light distribution, the high luminous efficiency, the relatively small lamp dimensions and the possibility of an extensive range.
