WAYNE, Pa., April 10, 2013 /PRNewswire/ — Independence LED, ( a leading U.S. manufacturer of the “Best Built LED Tubes,” today announced that the DesignLights Consortium(R) approved its groundbreaking, energy-efficient four-foot 12-Watt LED Tube.

At 2:23 pm on Tuesday, April 9, Charlie Szoradi, CEO of Independence LED, looked up from his laptop and said, “We got DLC.” He had just received the approval e-mail for DLC Qualified Products, and this benchmark in a 20-year career of energy efficiency including more than $3 million of recent investment in research and development and U.S. manufacturing. Across the conference table, Tyler Simays, one of Independence LED’s youngest energy analysts, beamed in response, “Excellent!”

The DLC listing is a historic benchmark in the “American Energy Revolution,” because it activates a new generation of technology sales. Most U.S. utility companies use DLC as an outside performance metric to guide LED tube rebate approvals. Now, the Independence LED tube has the ultimate triple play: American-made, lowest energy consumption and rebate ready. Some utilities offer up to 50 percent in rebates, making this the proverbial Game Changer.

DLC Qualified Products are also a powerful vote of confidence for facility managers that continue to see weak product engineering from China. The Independence LED tube has the most advanced patent-pending thermal management with aircraft-grade aluminum deep fin heat sinks and external “independent” drivers.

More than 2.3 billion fluorescent tubes are in American ceilings. So, this 12-watt tipping point brings major change to inefficient 40- and 32-watt fluorescent tubes that have dominated commercial lighting since the 1950s.

The Independence LED tube saves 65 percent over fluorescent tubes and last up to 20 years in common applications like offices, schools and retail stores. The company doubled the sale of its LED tubes each of the past four years and has installations ranging from the Fortune 100 to the U.S. government civilian and military. The DLC submission focused on retrofitting common 2-foot by four-foot ceiling fixtures that typically hold up to four fluorescent tubes, and Independence has already submitted additional configurations for review.

Mr. Szoradi said, “I was always inspired by Edison’s quote, ‘There’s a way to do better … find it’ and now, 100 years later, our team has done it. We have engineered and commercialized the best built LED tube. The annual savings are in the billions.”

MORE on DLC Qualified Products for the QPL – Qualified Products List

DLC focuses on the net output of usable light from a fixture (efficacy).

Fixtures such as acrylic prismatic or parabolic impact the output of light in different ways. Overall, fixtures reduce the amount of output from either a fluorescent or LED tube so the net lumens per watt is lower than the output per tube in isolation.

For Independence LED, third party testing on typical 12 Cell Parabolic (2’ X 4’) fixtures, such as the ones used for DLC lighting reviews for the DLC LED category, results in an efficacy of 83% to 88%. In short, 12% to 17% of the light is lost through the fixture. The data sets average to a fixture efficacy of 85% .

By contrast, fluorescent tubes typically only have a fixture efficacy of 65% given that about a third of the light is wasted going up into the fixture vs, toward the floor.

Fluorescent Tubes: 360° with omni-directional light – A portion is wasted going up

LED Tubes: 120° with directional light – The output is focused toward usable areas

The DesignLight Consortium® (“DLC”) Qualified Products List (“QPL”) is for high-quality, high-performing commercial LED products. Each of the products listed on the QPL have met the DLC’s minimum performance and other requirements. DesignLights® Consortium anticipates updating their online Qualified Products List every two weeks.

Buyers and Distributors  ask about DLC Lights relative to the Qualified Products List, and DLC LED tubes are increasingly high in demand within the overall category of DLC LED listed products. Rebates drive the ROI that is the engine of the energy reduction marketplace and the category of DLC Lighting is central to the LED rebates for commercial lighting for many U.S. utility companies.

The first Independence LED submission for the DLC LED within the DLC Lighting category  included all three color temperatures for the  4′ 12 Watt LED tubes, to retrofit fluorescent tubes in 2′ x 4′ troffers that are such common fixtures across the U.S. and around the world. This retrofit configuration is based on a set of four tubes (R4).

For Independence LED, multiple wattage and color temperature tubes are now on the Design Lights Consortium (DLC) Qualified Products List:

Please note that Independence LED’s DLC Listed retrofit configurations are the light engine modules that power retrofits for UL Listed Parking Garage, Low Bay, and High Bay Fixtures. This yields multiple output options to meet the illumination and REBATE needs of different facilities.
