Almost all surfaces reflect light to some extent. Walls, floors, ceilings, tables, computer screens, machines, and the materials being worked on can all be sources of indirect glare for a worker. The key to reducing indirect glare is the proper positioning of the luminaire in relationship to the task or surface, and low surface brightness of the luminaire. Color - Color rendering is also a critical element in industrial lighting systems. As lamp technology has evolved, the ability to get good color rendering without sacrificing efficiency has vastly improved.
Metal halide is the dominant source for indoor industrial lighting today.
The metal halide lamp's combination of high efficiencies and good color rendering make it one of the best choices for general industrial lighting. However, if color is critical, the new tri-phosphor fluorescent lamps, available in a variety of color temperatures and color rendering indexes, also provide outstanding efficiency and produce the highest color rendering for color sensitive industrial lighting applications. Ballast Systems - HID systems are used in a myriad of industrial applications. How they are used in your facility will depend upon the unique environments found there. Take a moment to review some of the important environmental factors involved in selecting HID Ballast Systems.
