Integrated LED Lamps Testing Results: A Sampling of Products from Major Retailers

Retail LED Lamp Testing
What’s really out there for consumers to purchase?
CALiPER Retail Replacement Lamp Special Reports Anonymous purchases Omnidirectional, directional, and decorative lamps Wide variety of manufacturers and retailers LM-79 photometric testing (sphere only) conducted on three samples of
each lamp
www.ssl.energy.gov 3 | Solid-State Lighting Program
Products purchased July & August 2010 Large disparities between high performing and low performing
products Most of the lamps failed to meet basic performance parameters for use
as replacements for incandescent or halogen lamps
Wide differences among retailers Most carrying (at least some) very low quality products
Differences among manufacturers Some consistent, some very inconsistent in performance across different
products
Summary: Initial Retail Replacement Lamps Study

Retail Replacement Lamps, Take Two!
38 Total Products. 9 Different Retailers. 18 Different Manufacturers.

Not All LEDs Are Created Equal
Range of efficacies continues to be wide, and getting wider Range partly due to numerous product types, with different requirements Maximum efficacy continues to rise year by year Smaller range for replacement lamps, but similar average

CALiPER Test Results
www.ssl.energy.gov 24 | Solid-State Lighting Program
Overall performance generally much improved Higher lumen output and efficacy
Products reach higher lumen output milestones Better color rendering
Substantial increase in performance per dollar Cost still higher than incandescent or CFL
Increased prevalence of product labels
Some products still outside ANSI tolerances
Better at meeting manufacturer data
Equivalency claims not always met, although problems less frequent
There are still some products that would not make good replacements for conventional lamps—careful evaluation is important!
