Mercury vapor lamp
Introduction
High pressure mercury vapor lamps range between 10 and 100 times brighter than incandescent lamps (such as the tungsten-halogen) and can provide intense illumination over selected wavelength bands throughout the visible spectral region when combined with the appropriate filters. These illumination sources are highly reliable, produce very high flux densities, and have historically been widely used in many fields.
Advantages
1. High light efficiency
2. Excellent luminous maintain rate.
3. Color constancy
4. Suit for lighting indoor and outdoor
5. Widely used in Road, factory, wharf, supermarket, Home garages, apartment, floodlighting
