NOM-031-ENER-2019: Energy efficiency of LED luminaires for roads and public outdoor areas. Specifications and testing methods

Last updated: 12 April 2023

The standard establishes the specifications and test methods for efficient use of energy in lighting with light-emitting diodes (LEDs), intended for lighting roads and public outdoor areas.     


The main features of the update include:       

- the use of self-generating sources in alternating and/or direct current, with a nominal voltage up to 480V in alternating current and up to 100V in direct current    

- increasesing the energy efficiency values (lumens per watt)    

- increasesing the number of samples to be evaluated and hours that a lighting point must be tested for (maintained luminous flux test) to obtain the initial certificate
