New IEEE Standard – Active. The design of power systems supplying lighting loads of industrial and commercial facilities are covered in this recommended practice. Common power system considerations specifically related to lighting loads are discussed, including voltage drop, transients, flicker, and circuiting recommendations for various applications. General fundamental concepts of lighting design, including common light sources, control methods, and application techniques, are discussed. Industry-recognized lighting design organizations and applicable lighting codes are discussed and identified as further resources for the lighting designer.
