10/24/08 DOE Announces
Webinar on LM-80
On
September 30, 2008, the last remaining critical test procedure for the
U.S. Department of Energy’s ENERGY STAR Solid-State Lighting Program
was finalized by the Illuminating Engineering Society of North America
(IESNA), LM-80-08 Approved Method for Measuring Lumen Maintenance of
LED Light Sources.
The
finalization of this test procedure has resulted in a number of
questions by partners interested in how the test procedure will be used
for ENERGY STAR qualification. As a result of these questions, DOE is
hosting a webinar on October 30, 2008 from 2 – 3pm EST to review the
LM-80 test procedure and how it will be used in the ENERGY STAR
qualification process for SSL products. Presenters Jeff McCullough
(Pacific Northwest National Labs) and Kevin Dowling (Philips SSL
Solutions) will answer the following questions:
• What does LM-80
measure?
• How is the LM-80 test
conducted?
• How long does the test
take?
• What are the results
and how are they used by ENERGY STAR?
Registration is limited; please register ASAP
to receive information on the Webinar.
10/03/08 DOE Report Estimates
LED Savings in Niche Markets
DOE has released analysis
findings for niche markets where light emitting diodes (LEDs) compete
with or are poised to compete with traditional lighting sources (e.g.,
incandescent and fluorescent). The September 2008 report provides
estimates of current energy savings plus potential savings if these
markets switched to LEDs overnight.
Twelve niche markets were
analyzed, comprising four colored-light applications (traffic signals
and pedestrian crossings, decorative holiday lights, exit signs,
electric signage); six indoor white-light applications (recessed
downlights, refrigerated display cases, retail displays, task lights,
office undershelf lights, kitchen undercabinet lights); and two outdoor
white-light applications (street and area lights and step, path, and
porch lights).
LEDs in these markets are
already saving consumers nearly $1 billion in electricity costs. If
these markets switched to LEDs overnight, energy savings would be the
equivalent of taking 18 million residential households off the grid and
could save consumers more than $22 billion in electricity costs. To
download a PDF of the report, go to www.netl.doe.gov/ssl.
