September 11, 2008 - PureSpectrum, Inc. testing dimmable three-tube electronic ballast for popular commercial use CFL fixtures

September 11th, 2008

SAVANNAH, GA – At the request of two major lighting fixture manufacturers, ballast technology developer PureSpectrum, Inc. (Pink Sheets: PSPM) has developed a dimmable three-tube electronic ballast that will operate three standard wattages for pin-based Compact Fluorescent Lamps (CFL).  

The company, which developed and owns multiple ballast circuitry designs, has completed successful internal testing for a dimmable ballast model specially built to power 15-watt, 26-watt and 42-watt pin based CFL lamps. Pin-based CFL bulbs have gained enormous popularity in the commercial and industrial lighting market as an energy efficient alternative for down lighting, and PureSpectrum’s market research indicates that a better ballast for these wattages is being aggressively sought by high volume fixture manufacturers. 

“The pin-based CFL application is extremely important to the commercial and industrial light fixture market, and manufacturers of this application are seeking product improvement strategies to distinguish themselves in an increasingly crowded marketplace,” said PureSpectrum president and CEO Lee Vanatta. “Our CFL ballast technology was initially designed for an Edison-design socket, but the technology is flexible and scalable enough that we were able to make minor modifications and generate positive internal test results with pin-based CFL lamps.”   

According to industry analysts, CFL lamps are expected to be the fastest growing segment of the lighting industry through at least 2012 due to technology performance improvements, cost reductions and the worldwide quest for energy conservation. During 2006 more than two million bulbs valued at approximately $1.5 billion were produced, and production of CFL bulbs has grown by at least 35 percent annually since 2003 and grew by 43 percent in 2005 alone.  

PureSpectrum’s ballast would provide manufacturers with multiple marketing and performance benefits. With a multifunctional ballast, manufacturers could offer distributors one product to fit three separate lamp wattages. And while a wide range of purportedly dimmable CFL bulbs have been introduced in the last decade, the bulbs have been plagued by poor performance and questions about bulb longevity. PureSpectrum’s ballast model allows for true linear regressive dimming capability without shortening the life of the lamp, enabling commercial end users to take full advantage of energy conservation strategies such as daylight harvesting and occupancy sensory lighting.  

PureSpectrum has engineered multiple breakthroughs in electronic ballast circuitry for fluorescent lighting during the past two years and filed a patent earlier this year for a dimmable Edison-design screw-base CFL bulb. PureSpectrum’s technology advances have elicited strong interest from several global lighting manufacturers, and Vanatta said the company and its partners will continue to refine the technology and identify new potential avenues for revenue generation. 

“Our successful demonstrations with lighting manufacturers and data produced through independent performance testing have generated additional interest in the lighting community,” Vanatta said. “We have gained notoriety in the industry as a company that is truly engineering to improve lighting products and more fully meet the needs of consumers. We have addressed negative issues that dimmable CFL lamps must overcome, and the industry has responded with genuine interest in our technology.”
