NEMA publishes LE 6-2009 for luminaire target efficacy ratings

November 5, 2009 | By Anthony Capkun


The National Electrical Manufacturers Association (NEMA) has published LE 6-2009, “Procedure for Determining Target Efficacy Ratings for Commercial, Industrial, and Residential Luminaires”, which was last published in 2008.

LE 6 provides a procedure for determining of the target efficacy rating
(TER) for luminaires under laboratory test conditions, and describes
categories or types of products used in common indoor/outdoor lighting
applications. It does not apply to luminaires for specialized
applications, such as products intended to be aimed, accent luminaires,
rough- or hazardous-use luminaires, or emergency lighting. It is
recommended to be used only as a guide to help in the selection of
luminaires since TER does not address application characteristics such
as colour, uniformity, glare, etc.

The 2009 revision includes updates to the calculation of the
energy-effectiveness factor and clarifications to the luminaire types
and classifications.
