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.

Stabilization,e lamp and the voltage across the lamp. Over a wide range, the lamp voltage . is almost independent of the lamp current .; with increasing current the voltage decreases slightly for low loaded lamps and increases slightly for high loaded lamps (see Fig. 1.14).
