NEMA, or the National Electrical Manufacturers Association, is responsible for developing and maintaining safety standards for the proper manufacturing of electrical-based equipment, including the production of lighting, wire, cable and power-generating equipment in the United States. NEMA has developed a floodlight lighting specification, which categorizes floodlights according to the specific amount of light distribution.

There are seven types of NEMA flood lighting classifications, which are rated according to the beam spread degree, or amount of light distribution. Type 1 is classified as very narrow, with a beam spread of 10 degrees up to 18 degrees. Type 2 is classified as narrow, with a beam spread of 18 degrees up to 29 degrees. Type 3 is classified as medium narrow, with a beam spread of 29 degrees up to 46 degrees. Type 4 is classified as medium, with a beam spread of 46 degrees up to 70 degrees. Type 5 is classified as medium wide, with a beam spread of 70 degrees up to 100 degrees. Type 6 is classified as wide, with a beam spread of 100 degrees up to 130 degrees. Type 7 is classified as very wide, with a beam spread of 130 degrees or more.


There are more than 60 manufacturers operating in the United States, producing NEMA-certified floodlighting, spotlights and other high forms of intensity lighting. Some well-known examples include: Siemens Corp., Americord, New Pig Corp., Ruud Lighting Inc. and Bulbworks, Inc. Common examples of floodlights include: portable clamp lights, fluorescent lights, spotlights, stick lights, tripods and retractable lighting.


NEMA-certified floodlighting, spotlights and high-intensity lighting are typically used by emergency-response vehicles and personnel in large-scale emergency situations, such as search and rescue missions, large-scale auto collisions and emergencies. Floodlights are often used to increase the visibility of construction workers while stationed on bridges, highways, parking lots and other night-time work sites.
