Rosslyn, Va.-based National Electrical Manufacturers Association (NEMA) has published ANSI C136.37, "Solid State Light Sources Used in Roadway and Area Lighting."
The first solid state lighting (SSL) standard produced by ANSI-accredited standards committee C136.37, this standard defines interchangeability and some requirements for SSL source fixtures (also referred to as luminaires and LED or light-emitting diode fixtures). References to existing regional and international SSL standards are used to recommend guidance to utilities and manufacturers for harmonized solutions and expectations. C136.37 includes requirements for operating temperature, correlated color temperature, mounting provisions, dimming, ingress protection, and wiring and grounding. In addition, C136.37 sets protocol for surge-test waveforms, the basic insulation test, and specific product ratings.
