Description: MH lamps or metal halide lamps provide bright and powerful illumination, suitable for large areas that require ample lighting. Metal halide lamps consist of two vital components, which are the inner arc and outer bulb. The inner arc houses the mercury and metal halide salts. When you turn on the lamp, the electricity will heat-up the gas and salt. This will cause a reaction between the elements in which they are transformed into gas and eventually to white light. Whether you need a metal halide lamp or an LED light bulb, you can get it here MRO Supply.
