Goals of Industrial Lighting
• Provide energy effective lighting for spaces designed for light manufacturing and assembly tasks which require average light levels.
• Industrial tasks require higher light levels, such as cleanrooms or assembly of fine materials.

Quality lighting contributes to the comfort and productivity of warehouse and manufacturing personnel. It also contributes to their safety, especially around moving machinery. Glare control, balanced brightness ratios and reduced lamp flicker or strobe effect must be taken into account to ensure safety and security in the work space.
Brightness, Contrast and Reflectance
The ability to see detail is dependent on good contrast. When the task blends with the background it is difficult to see. If contrast is too great people may experience adaptation discomfort when looking from bright surfaces to very dark surfaces. People are most comfortable when the visual environment is relatively uniform. The following ratios are recommended by the IESNA for areas where reflectance of the work area can be controlled, and where control of the remote surroundings is limited.
Lamp Color Matters
Outdated fluorescent and HID lamps such as cool white and mercury are inferior at coloring rendering and are associated with noisy ballasts that often produced flicker in fluorescent lamps. Pozeen's LED highbay is good to provide high color rendering sources, and if used consistently, will allow people to see color accurately and work in a comfortable and safe environment.
When the brightness ratios exceed maximum recommended values, disturbing or debilitating glare can result. To minimize glare-producing conditions, consider the following:
