Independence LED reports that US DOE found its LED tubes 15% more efficient than competitors

Report also indicates that Independence LED tubes are potentially safer than competitor products

WAYNE, PA -- Independence LED Lighting, the award-winning U.S. manufacturer of commercial LED lighting, announced today that according to U.S. Department of Energy (DOE) report data, Independence LED tubes are 15% more efficient in lumens per watt than the average from the field of over 30 LED manufacturers, including tubes from major competitors Philips, Cree, and Osram Sylvania.

In the report, the DOE found that LEDs are more efficient than ever. The CALiPER Summary Report 21: Linear (T8) LED Lamps concludes: “Compared to previous CALiPER testing of the same product type, there have been notable performance gains. With the efficacy (lumens/watt) of many lamps now equivalent to or exceeding that of fluorescent lamps.” (Section: Conclusions - page 20)

Independence LED has stayed well ahead of the curve. As the below chart indicates, the U.S.-made Independence LED tube is 15 lumens per watt more efficient than the average of the tested field (15.95%) and over 10% more efficient than global lighting companies like Philips, Osram Sylvania, and Cree.

Manufacturer: Lumens/Watt DOE CALiPER Test ID #
Independence LED 109 13-31
Philips Lighting 99 13-29
Cree 96 13-33
Osram Sylvania 94 12-111
Average for test 94 (across 31 tested products)

The 2014 report indicates that, based on their design, Independence LED tubes are potentially safer than competitor products. Typical fluorescent fixtures bring line voltage into the fixture via alternating current (AC), and then convert it through the ballast to lower-voltage direct current (DC). Internal driver LED tubes -- like most of Independence LED’s competitors -- override the ballast, creating a potential safety issue. As the DOE says in their March 2013 CALiPER Report: Recessed Troffer Lighting: “There is ongoing concern in the lighting industry over the safety of fluorescent troffers when they are converted using LED T8 lamps or retrofit kits.” (Section: Electrical Safety and Certifications of Retrofitted Troffers - page 25)

The 2014 CALiPER Report addressed this safety concern directly, specifically citing the Independence LED as a safer option. The report reads: “Two other products [13-31 Independence LED and 13-33 Cree] did not use the sockets for supplying power to the lamps (although 13-31 did use the sockets for supporting the lamp). Like products that can use an existing ballast, these products could reduce safety concerns related to future modifications.” (Section: Electrical Characteristics - page 18).
