Newest Electronic Ballasts Cut Energy Costs by Up To 45%

The NEMA Premium Electronic Ballast Program is another industry effort to widen the use of high-efficiency products.  Late in 2009, NEMA published BL 2-2009 Energy Efficiency for Electronic Ballasts for T8 Fluorescent Lamps, which revised the 2007 version.  NEMA’s BL 2 contains energy-efficiency requirements for evaluating electronic ballasts designed for use with four-foot 32W T8 fluorescent lamps with a lumen output greater than or equal to 3100 lumens. It covers definitions, requirements, and markings.  NEMA’s Ballast Program provides the method for identifying the most efficient T8 fluorescent ballasts available in the market.
