Protected Standard Metal Halide lamps feature a robust outer glass envelope that shields the inner arc tube, enhancing durability and preventing damage. They offer reliable performance with good color rendering and are commonly used in outdoor and industrial applications where protection from environmental factors is needed.
Standard Metal Halide (MH) lamps are a type of high-intensity discharge (HID) lighting that produce bright, white light by passing an electrical current through a gas-filled arc tube containing metal halide salts. They offer good color rendering but have slower start-up times and less efficiency compared to pulse-start versions. These lamps are commonly used in street lighting, warehouses, sports arenas, and other large spaces requiring high illumination.
