What is the Difference Between Metal Halide and Multi Vapor?

Metal halide and multi-vapor lamps are both types of high-intensity discharge (HID) lamps that contain a mixture of gaseous components, including mercury and metal halides. The terms "metal halide" and "multi-vapor" are often used interchangeably, as there is no significant difference between the two. Here are some key points about these lamps:

• Function: Both types of lamps create light by passing an electric arc through a mixture of gaseous components, including mercury and metal halides.
• Metal Halide: Metal halide lamps are a form of light source that creates light via an electric arc within a quartz arc tube containing the gases and the arc. They are similar to mercury vapor lamps but contain more gaseous components along with mercury vapor.
• Multi-Vapor: The name "multi-vapor" is a synonym for metal halide lamps, deriving from the fact that these lamps contain several vapors of metal halides along with mercury.
• Compatibility: Mercury vapor bulbs can be used in metal halide fixtures, but metal halide bulbs cannot be used in mercury vapor fixtures.

Both types of lamps are part of the HID family of bulbs and are known for their high efficacy, excellent color rendition, long service life, and good lumen maintenance. They are commonly used in outdoor applications and commercial interiors.

Comparative Table: Metal Halide vs Multi Vapor

There is no difference between metal halide and multi vapor lamps, as both names describe the same form of lamp. These lamps are a type of High-Intensity Discharge (HID) lamp, which also includes mercury vapor and high-pressure sodium lamps. The following table highlights some key features of metal halide and multi vapor lamps:

In summary, there is no difference between metal halide and multi vapor lamps, as they are the same type of lamp with the same basic components and functionality.
