NEMA’s LE 6-2014 Determines Target Efficacy Ratings for Luminaires

NEMA

The National Electrical Manufacturers Association (NEMA) has published LE 6-2014 Procedure for Determining Target Efficacy Ratings for Commercial, Industrial, and Residential Luminaires. The revised procedure now includesLED technology.

The procedure’s purpose is to

• provide the lighting design community and procurement officials with a practical and uniform method for calculating a metric to evaluate and compare the energy effectiveness of luminaires
• enable construction or renovations to focus on sustainable design by evaluating the energy performance of luminaires
• provide electrical utilitieswith way to establish performance criteria for luminaires, to use with energy-savings rebate programs
• provide a methodology that considers lamp and ballast components as well as the effectiveness of the luminaire optics to deliver light to an intended task
• define categories for types of luminaire products based on function, physical or dimensional attributes, and optical characteristics of luminaires to enable qualified energy comparisons within a category of product
• preserve for the luminaire manufacturers and the lighting industry the right to use laboratory facilities, testing methods, and completed test data that currently exist and are in accordance with approved industry standards
