Residential Product Performance Scale

Version 1.1

LED Lighting Facts developed residential and commercial product performance scales to help partners evaluate and determine if LED products are appropriate for a given application. The scales compare the performance values for the five metrics identified on the LED Lighting Facts label to performance values of standard lighting technologies. The residential product performance scale can also be downloaded and printed using the "Download as PDF" link found above.
 

The Anatomy of the Lighting Facts Label
 

Light Output (Lumens)


Measures light output. The higher the number, the more light is emitted.*
Reported as “Total Integrated Flux (Lumens)” on LM-79 test report.

Note: recommended LED equivalency levels and performance data for incandescent, halogen, and fluorescent products were based on benchmark testing of conventional light sources by Pacific Northwest National Laboratory (PNNL) on behalf of the DOE Solid-State Lighting Program. The levels were used in the development of the initial ENERGY STAR SSL Luminaires and Integral LED Lamps criteria.

* Light output values for luminaires are derived from testing the entire luminaire (light source and fixture) and evaluating and losses that occur.

** The L Prize (www.lightingprize.org) is the first government-sponsored technology competition designed to spur lighting manufacturers to develop highquality, high-efficiency solid-state lighting products to replace the common light bulb. 

† The recommended LED directional replacement lamp lumen level is equal to the target incandescent/halogen wattage multiplied by 10.

Efficacy (Lumens per Watt)


Measures efficiency. The higher the number, the more efficient the product.*

The levels were used in the development of the initial ENERGY STAR SSL Luminaires and Integral LED Lamps criteria.

* Efficacy values for replacement lamps correspond to lamp efficacy, while values for luminaires correspond to luminaire efficacy, which is derived from testing the entire luminaire and takes into account light losses from luminaire optical components.

† The recommended LED directional replacement lamp lumen level is equal to the target incandescent/halogen wattage multiplied by 10.

Color rendition is the effect of the lamp’s light spectrum on the color appearance of objects.

Correlated Color Temperature (CCT)


Measures light color.

“Cool” colors have higher Kelvin temperatures (3600-5500K).
“Warm” colors have lower color temperatures (2700-3500K).
Color temperatures higher than 6500K are outside of the defined region for white light, but may be appropriate for outdoor applications.
 

2700K-4500K: Appropriate for indoor residential applications, 4500K-6500K: Appropriate for outdoor and commercial indoor applications, 6500K-10,000K: Only acceptable for commercial outdoor applications
