PureSpectrum Dimmable Linear Fluorescent Ballast Meets Standards for NEMA Premium Efficiency Electronic Ballast Program

Testing Shows That PureSpectrum Ballast Exceeds Requirements in Three Critical Performance Categories

SAVANNAH, GA--(Marketwire - April 17, 2008) - Results from independent testing definitively indicate that a dimmable ballast for linear fluorescent lamps designed by PureSpectrum, Inc. (PINKSHEETS: PSPM) exceeds performance standards set forth by the National Electrical Manufacturers Association (NEMA) Premium Efficiency Ballast Program.

The tests were conducted at Independent Testing Laboratories, an independent, non-affiliated facility in Colorado, and the data generated from the testing series shows that a 32-watt T8 prototype bulb powered by PureSpectrum's proprietary ballast circuitry design surpassed the requirements for a premium efficiency ballast in NEMA's critical performance categories: ballast frequency, power factor and total harmonic distortion.

The NEMA Premium Electronic Ballast Program provides the recognized method for identifying the most efficient T8 fluorescent ballasts available in the market and identifies ballast models and designs which are consistent with the Consortium for Energy Efficiency (CEE) specifications for high performance lamps and ballasts.

The PureSpectrum prototype tested was the first iteration of technology engineered to create a dimmable electronic ballast for linear fluorescent bulbs which would enable true linear regressive dimming. The innovative circuitry topology is applicable for any fluorescent lamp design, features very high power factor correction with no loss of light output and enables PureSpectrum's electronic ballast to perform comparably or outperform brand name linear fluorescent ballasts. Compared to standard dimmable electronic ballasts, PureSpectrum's ballast also contains significantly fewer electronic components, and the company anticipates the cost to manufacture will be substantially lower than the cost to make a conventional dimmable ballast with more than one hundred electronic components.

"Our development process has always been geared toward producing technology of the highest possible quality that can be manufactured and sold for a reasonable cost," said PureSpectrum president and CEO Lee Vanatta. "Our technology has now met the internationally recognized standard for excellence for electronic ballasts, and our dimmable ballast has a parts count comparable to a non-dimmable electronic ballast. Essentially, we have built a dimmable electronic ballast that can be manufactured and sold for the same price as a non-dimmable electronic ballast. Ultimately, a lighting manufacturer will be able to sell a truly dimmable linear fluorescent ballast for the same price as a non-dimmable linear fluorescent ballast."

PureSpectrum is at the leading edge of a wave of innovation in the rapidly growing $10 billion electronic ballast industry driven by the increasingly urgent demand for improved energy efficiency. Manufacturers attempting to retain brand loyalty have already begun the search for new technologies which will meet the price points and performance standards of an increasingly impatient consumer population.

Linear fluorescent lighting is the most prevalent product for lighting commercial and other non-residential settings, but until now the high retail cost of dimmable ballasts prohibited the widespread adoption of dimmable linear fluorescent bulbs. Until recently, linear non-dimmable fluorescent bulbs were powered by inexpensive and inefficient magnetic ballasts, but the U.S. Federal Minimum Energy Standards enacted for fluorescent lights by the U.S. Department of Energy has forced the commercial lighting industry in the U.S. to shift rapidly toward more energy efficient electronic ballasts.

"My major effort with this ballast was in the dimming linearity and heat reduction of the inductor," King said. "With this first version, I did not focus as much on efficiency or power factor, but both of those performance categories were still satisfactory. That tells me that this new circuitry has come a long way in a short time, and there is still room for improvement going forward."
