Procedure for Determining Luminaire Efficacy Ratings for Fluorescent Luminaires

NEMA LE 5-2001 | Status: Active | ID: 100137

Establishes a luminaire efficacy rating based on rated lumens per watt and organizes luminaires into categories that will reasonably represent the characteristics of high-volume luminaires. Serves as the basis for the National Voluntary Information and Rating Program for widely used luminaires.

When rating a fixture in accordance with EPAct 1992, use this Standard. For other purposes, see NEMA LE 6, a newer Standard for luminaire efficacy that supersedes the LE 5 series.
