- Commercial Lighting Technologies
Commercial lighting is the use of light as a means to fill the needs of business, meaning that it is a tool to increase profit. It also refers to light fixtures in stores, offices and other non-residential buildings. Applications are as diverse as the variety of businesses – thus designers and manufacturers of commercial lighting fixtures keep the needs of their consumers foremost for the mutual benefit of both. Architects and interior designers, in conjunction with electrical engineers, develop commercial lighting plans to balance functionality with aesthetics.
There are a number of lighting technologies available for commercial use. They vary widely in efficiency, application and energy consumption.
Incandescent lighting, invented in the 19th century, uses lamps that are energy inefficient compared to other technologies, emit heat and have a relatively short lifespan. Their use in commercial applications stem from their low upfront costs, availability and the fact that the light they produce is similar to natural sunlight.
Fluorescent lighting was commercially introduced in the 1930s and quickly became popular because of their energy efficacy, long lifespan in comparison to incandescent lighting and lower overall cost.
High Intensity Discharge (HID) lighting, or metal halide lighting, is commonly used in industrial applications such as warehouses or factory grounds. They produce a large amount of very bright light, enabling the coverage of wide open spaces. Older high pressure halide lights are relatively inefficient but modern low pressure sodium models are comparable to fluorescent lamps in their consumption of energy. High pressure sodium light has a pink-orange glow and is used when good color rendition isn’t critical. Metal halide provides clean white light and better color rendition.
