1. NEMA Publishes ANSI_ANSLG C78.81-2013
American National Standard for Electric Lamps—Double-Capped Fluorescent
Lamps—Dimensional and Electrical Characters - ANSI_ANSLG C78.81
details the physical and electrical characteristics of the principal types of
fluorescent lamps intended for application on conventional line frequency
circuits and electronic high-frequency circuits. This revision includes the
addition of four new fluorescent lamp data sheets for the following lamps: http://www.nema.org

2. NEMA Publishes NEMA LSD 67-2013 Low Mercury Controllable Fluorescent
Systems - Discusses technical tradeoffs associated with
reduced mercury dosing in fluorescent lighting systems and their environmental
impacts. NEMA members are committed to providing fluorescent lighting systems
that allow lamps to be controlled to save energy, while reducing the mercury
content in the lamps to the extent that it is technically possible without
sacrificing functionality. http://www.nema.org/Standards/Pages/Low-Mercury-Controllable-Fluorescent-Systems.aspx
3. Independence, MO Expects Large Savings with LED Streetlights - The city-owned utility, Independence Power
and Light, has calculated that moving from HID fixtures to the new LED fixtures
it expects to save roughly $450,000 per year in energy and maintenance costs.
The new lights will give off a white light, improving the quality of light, and
when citizens were informally surveyed, more than 75 percent gave a favorable
rating to the new lights. The estimated cost of the project is $4.2 million,
and the city said it will use $250,000 in funds from the federal stimulus bill
to help pay for the streetlight LED project.

4. PSNH Downplays City Savings of Converting to LED Street Lights -
Public Service of New
Hampshire is downplaying the savings that Manchester might realize by
converting to efficient LED street lights. The city has nearly 9,000 street lights and is by far PSNH's largest
municipal customer. Its electric bill to PSNH to keep the street lights on is
approximately $1.4 million annually. But under the tariff structure proposed by PSNH the city it would only see an overall estimated reduction
in costs of 8 percent. This is because
the city already uses HPS
lights, which are considered relatively efficient, consuming 50-70 watts; LEDs
consume 40 watts. Under PSNH's proposal, communities would bear
all the costs associated with the purchase and installation of lights. At a
cost of $300 per light, the
purchase of 9,000 lights could cost nearly $3 million. 12/24

Lighting Controls Handbook by Craig DiLouie - Intended for energy managers, electrical engineers, building managers,
lighting designers, consultants, and other electrical professionals, this book
provides a practical description of major lighting controls types and how to
apply them. It's a comprehensive step-by-step educational tour of lighting
automation technology and its practical design and application, with useful
discussion about the purpose and benefits of lighting controls, emphasizing the
achieving of relevant energy savings, as well as support of occupant visual
needs and preferences. http://ecmweb.com/lighting-controls-handbook
6. USGBC Certifies 20,000th LEED Commercial
Project - The
20,000th LEED certification for a commercial building has been awarded to the
Green Mountain Coffee Roasters plant in Knoxville, Tennessee, under LEED for
Commercial Interiors. The Knoxville plant is the seventh LEED-certified facility
for Green Mountain, based in Waterbury, VT. http://www.usgbc.org/articles/us-green-building-council-certifies-20000th-leed-commercial-project
7. The University
of Minnesota's Lighting Retrofits - The University of Minnesota campus in
Minneapolis is poised for major changes. As with so many other institutional and commercial
facilities, the university is looking high and low for new technology
applications that will help hold down costs related to building operations and
maintenance. A sizable part of the attention being paid to savings relates to
retrofits of existing buildings involving LED lighting. http://www.facilitiesnet.com/ See the video at: A Closer Look Online

DOE
Issues Guidelines for Conducting and Sample Test Results for Highly Accelerated
Life Tests Known as "Hammer Testing" - While
lifetime in LEDs is how long an LED lasts until it emits no light, it is the
useful lifetime that is important. A number of organizations have come out with
procedures that give a good estimate of average lifetime based on a test of
lumen maintenance. This is used to estimate useful lifetime usually referred to
LM-79. The DOE has published the detailed protocol for "Hammer
Testing” luminaires along with an explanation of their usefulness and rational. http://www.sslighting.net/news/?id=123669#top
9. WattStopper
Publishes New Product Selection Guide (PSG) - A comprehensive catalog of
energy-efficient lighting controls and services that help enable a net zero
future. The PSG is available in print and as an eBook, and for the first time
the content is also available as a mobile app.
10. Electricity
Costs and Economics Report - Electricity is the most important energy source in the modern age but
also the most ephemeral, a source that must be consumed as fast as it is
produced. This makes modeling the economics of electricity production more
complex than carrying out the same exercise for other products. This report examinesthe optimum balance between renewable
and conventional power generation in a carbon-constrained world. Available
