Commercial Lighting

Commercial lighting is designed to illuminate commercial and industrial environments. There are many different types of products. Examples include incandescent, halogen, fluorescent, high intensity discharge (HID), low pressure sodium (LPS), light emitting diode (LED), and neon. Light fittings, lighting controls, and lighting requirements are also important specifications to consider. Commercial lighting suppliers may describe their products as architectural lighting or decorative lighting; outdoor lighting or security lighting; and factory lighting or warehouse lighting. Flood lights, high intensity lighting, office lighting, and solar lighting are commonly available.

Commercial lighting may use incandescent light, halogen light, or various forms of fluorescent light. Incandescent lighting is relatively inexpensive, but is also the least efficient form of electric lighting. Halogen lights have a longer life than incandescent lights, but are not as efficient as fluorescents. There are three main types of fluorescent lamps in commercial lighting: halophosphor, triphosphor, and compact fluorescent. Halophosphor or standard fluorescent lighting uses 70% less electricity than incandescent globes. Triphosphor tubes are even more efficient, and provide better color rendering. Compact fluorescent lamps (CFL) have electronic ballasts and starters. CFLs use the same bayonet or screw bases as incandescent globes, but are up to five times more efficient than incandescents.

High intensity discharge (HID) lighting is a type of commercial lighting used in outdoor applications, and in buildings such as warehouses and factories which have high ceilings. HID lights contain compact arc tubes that enclose various gases and metal salts. There are three main types of products: mercury vapor, metal halide, and high-pressure sodium (HPS). Mercury vapor lamps emit light as the result of the passage of an electrical current through ionized mercury vapor. Metal halide lamps produce light from not only mercury, but also halides of metals such as sodium, scandium, indium, and dysprosium. HPS lamps are also available. This type of commercial lighting emits a strong yellow light of a single wavelength.

Commercial lighting includes low pressure sodium (LPS) or sodium oxide lamps, LEDs, and neon lights. LPS lighting has a very long rated life and a light output that remains stable over time. They have poor color characteristics, however, and are mainly used in applications where lights quality is not a primary consideration. Light emitting diodes or LEDs are used in commercial lighting application as well as for signs, traffic signals, and stop lights. Neon lights are not very energy efficient, and are used mainly in decorative applications.
