PureSpectrum Dimmable Ballast Technology Compatible With Daylight Harvesting and Sensor Lighting

Low Manufacturing Cost Makes Innovative Dimming Circuitry Perfect Fit for Green Lighting Programs

SAVANNAH, GA--(Marketwire - April 22, 2008) - Daylight harvesting and other sensory lighting control programs are often mentioned as the future of environmentally friendly artificial lighting, and PureSpectrum, Inc. (PINKSHEETS: PSPM) has developed proprietary dimming ballast circuitry which would lower the cost to manufacture these innovative lighting technologies.

Daylight harvesting refers to the recently introduced practice of regulating artificial light according to the available amount of ambient or natural light in a room. A dimmable ballast equipped with a sensor detects the amount of ambient light and reduces electric light when more sunlight is available. Because less light is needed during daylight hours, energy cost and consumption are both dramatically decreased.

Until the development of PureSpectrum's dimming technology for linear fluorescent ballasts, the high cost of dimmable ballasts has kept daylight harvesting and other sensory lighting control systems on the fringes of the lighting industry. PureSpectrum executives expect the company's unique and innovative ballast technology to bring daylight harvesting into mainstream usage by making it more affordable to implement for large commercial settings with abundant natural light.

Fluorescent lighting dominates the general lighting market and will continue to expand its market share as new technologies are developed to improve energy efficiency, affordability and performance. With more than a billion electronic fluorescent ballasts in use in the United States alone, the electronic ballast market already exceeds $10 billion per year and more than one hundred million new electronic ballasts are produced each year. About 35 percent -- 30 million -- electronic ballasts in use are near external light sources, making daylight harvesting an ideal option to significantly decrease energy usage. However, per unit prices of more than $100 for dimmable linear fluorescent ballasts has prevented the widespread adoption of any dimming control system featuring linear fluorescents.

PureSpectrum's dimmable ballast is expected to be substantially less expensive to manufacture than conventional dimmable ballasts for linear fluorescents, because it only contains about 30 electronic components compared to well more than 100 components found in conventional dimmable electronic ballasts. The PureSpectrum ballast is operated by approximately the same number of parts found in inexpensive, non-dimmable ballasts for linear fluorescents.

"The secret to our technology is in the circuitry rather than the expensive individual components and pieces," said PureSpectrum president and CEO Lee Vanatta, who said PureSpectrum's preproduction prototypes were built for less than $10 in components cost without bulk purchasing discounts and using readily off-the-shelf electronic components. "When coupled with photovoltaic daylight harvesting controls, this technology would enable the installation of a lighting control system to regulate energy usage without an enormous up-front capital investment. The cost savings in production for the manufacturer would ultimately be passed on to the end user, making the use of daylight harvesting a more viable energy conservation solution in the short term."

Recent independent testing showed that a two-tube, 32-watt T8 prototype bulb powered by PureSpectrum's proprietary ballast circuitry surpassed the requirements for the National Electrical Manufacturers Association's premium efficiency ballast program. The circuitry addresses any fluorescent lighting application, enables linear regressive dimming and features high power factor correction.
