Opened October 6, the Nancy Rutchik Red Maple Rill is the newest and premier addition to the Dallas Arboretum. The 2 acre rill features a collection of over 80 varieties of 200 signature Japanese Maples that follow a winding stream and paved walkways leading into the Martin Rutchik Concert Lawn. Rather than using the R40 175W mercury vapor lamps that would have required ballast boxes to be mounted to trees, Lighting Science Group worked with Unique Lighting of Texas to illuminate the area with the Definity PAR30 LED bulbs.

“While the gardens are beautiful during the day, at night the lighting is so wonderful it makes you feel as though you are in a magical land,” said Nancy Rutchik, commissioner and funder of the maple grounds.

The LED bulbs used beautifully highlight the trees without costing the Dallas Arboretum unnecessary electricity and maintenance expenses; the entire system consumes only 1830 watts.  That’s about the same amount of watts used for any average hairdryer and is dwarfed by the 21,350 watts figure required by a mercury vapor lamp substitute.

Visitors now continue to return to the gardens to see them lit in the evenings during the Arboretum’s Concert in the Garden series and for various after hour’s events and wedding receptions.

Lighting Science Group Corporation today notified the U.S. Department of Energy (DOE) that it has developed with Light Prescriptions Innovators, LLC (LPI) a highly efficient, high output and low cost 60-watt replacement LED bulb, and will submit it for testing to win the Bright Tomorrow Lighting Prize (L Prize) competition. The bulb design is based on patented and patent-pending technologies developed by both companies.

The Energy Independence and Security Act of 2007 established the L Prize to promote the development of a highly efficient, high quality LED replacements for the traditional 60-watt light bulb—the most widely used light bulb in America. Incandescent lights are wasteful and energy-hungry—DOE estimated that lighting accounted for 25% of all electric energy use in the U.S. in 2009—offering a rapid and practical path for significant energy savings from LED lighting.

The L-Prize criteria seemed futuristic when first announced, requiring a light bulb that works in current sockets and gets six times the energy efficiency (measured in lumens of light produced per watt of electricity used) of an incandescent and almost double the efficiency of a compact florescent lamp, while meeting other high standards for color rendering, life, quality, cost and availability.

“This bulb is yet another example of how Lighting Science Group is revolutionizing the science of light to produce state-of-the-art LED products that deliver on the promise of LED technology and further it’s widespread adoption, right here in America,” said Fred Maxik, founder and chief technology officer of Lighting Science Group.  “We are confident that our LED bulb developed in partnership with LPI meets or exceeds all of the criteria for the L Prize, making it a strong contender to win the competition, but we also believe that developing this product will further accelerate the transformation of the lighting industry to highly efficient LED technology.”

“This LED bulb will help accelerate America’s shift away from inefficient, dated lighting products to innovative, high-performance products,” said Roberto Alvarez, chief executive officer and president of LPI. “We applaud the U.S. government for challenging the industry through this contest to develop affordable and ultra-efficient LED bulbs that meet real-world user demands.”

In addition to a significant cash prize, the first manufacturer to fully meet the competition’s requirements will also be in consideration for federal purchasing agreements, utility programs and other incentives. However, the stakes are much higher than that. Energy efficiency means cost savings for the consumer, but on a national scale it also means less reliance on imported fossil fuels, greater national energy security, reduced pollution, and more innovation-driven clean-tech American jobs. According to DOE, an LED replacement for the approximately 425 million 60-watt incandescent bulbs sold each year could save 34 terawatt-hours of electricity in one year, enough to power the lights of 17.4 million U.S. households and avoid 5.6 million metric tons of carbon emissions annually.
