High-intensity discharge lamp

A lamp that produces light by passing an electrical current through a gas or vapor under high pressure. HID lamps have a long life and consume little energy to produce a great amount of light. However, they distort the color rendition of objects and are used mostly as ambient lighting for commercial interiors. Ballasts are required to start the lamp. Types include mercury vapor lamps, metal-halide lamps, and sodium vapor lamps. The different types contain different gases, which produce different colors of light.

This interim' partnership will aim to strengthen the capacity of countries worldwide to store mercury, reduce stockpiles of mercury originating in primary extraction of the heavy metal, promote risk awareness and projects to reduce the use of mercury in non-industrial mining operations (where it is estimated that ten million miners and their families are exposed) and reduce the use of mercury in products such as thermometers and high-intensity discharge lighting systems and in processes such as certain types of paper manufacturing and the production of plastics.
