LUXADD Express T5 Retrofit Kit: Greener, more efficient fluorescent lighting saves up to 73% on energy costs with a rapid 1 year ROI (Return on Investment).

Miami, FL (PRWEB) April 26, 2012

LUXADD – maker of the only Made-In-The-USA T5 Retrofit Kit for older, T12 fluorescent lights that are being phased out in the U.S.– will be introducing their energy-saving lighting technology to a large group of energy professionals attending the EMC show.

The West Coast Energy Management Congress(EMC) is the largest energy conference and technology expo held on the U.S. West Coast specifically for business, industrial and institutional energy users. It brings together the top experts in all areas of the field related to energy efficiency, facility optimization and sustainability. This is the perfect event for presenting LUXADD lighting and energy-conservation technology to members of the Association of Energy Engi…………… continues on Seattle Post Intelligencer

DC-Powered LED Lighting Could Lower Electricity Bills, Study Says
News from Environmental Leader:

A direct current electrical power system may be the most economic way to power lights in commercial buildings, according to a paper by Carnegie Mellon University researchers.

For more than a century, electric power has been produced and distributed using alternating current technology. But the DC system, pioneered by Thomas Edison in the 1880s, could have particular benefits for buildings that use solar photovoltaics, according to Edison Revisited: Should we use DC circuits for lighting in commercial buildings?, published in the journal Energy Policy.

CMU researchers examined the economic feasibility of operating several lighting technologies and scenarios in a 48,000-square-foot building using either a central DC power supply or traditional AC grid electricity.

They found that using DC instead of AC for fluorescent lighting yields the same or slightly higher costs. But if LEDs are installed instead of fluorescent lamps, the CMU researchers found a savings of $ 24,000 per year using DC. If the LEDs are powered with solar PV power augmented with grid electricity, even bigger savings can be gained by using DC, according to the research.

And as the cost of…………… continues on Environmental Leader
