May 30, 2007 - PureSpectrum, Inc. developing technology to improve half-bridge ballast performance

May 30th, 2007

SAVANNAH, GAEngineers from PureSpectrum, Inc. (Pink Sheets: PSPM) have developed a circuitry modification which could change the performance and popularity of Compact Fluorescent Light (CFL) bulbs. 

In response to feedback received during meetings with major lighting manufacturers which took place during Lightfair International in May, PureSpectrum plans to integrate its proprietary circuitry topology with the industry standard half-bridge ballast design which powers most fluorescent lighting. The resulting design is expected to enable more rapid illumination for CFL bulbs while retaining high levels of energy efficiency and without degrading the lifespan of the plasma which lights the fluorescent tube. 

According to recent independent tests performed by NVLAP-accredited testing facility Intertek, PureSpectrum Technology improves the run-up delay time for CFL bulbs manufactured by industry leaders Phillips,

Sylvania and GE by as much as 400 percent. PureSpectrum engineers are nearing the completion of prototypes which splice specific components found in PureSpectrum Technology with existing half-bridge ballasts to create circuitry which will virtually eliminate illumination delays without sacrificing bulb longevity.  

While manufacturers have already demonstrated interest in PureSpectrum Technology as a comprehensive solution, PureSpectrum president and CEO Lee Vanatta believes the introduction of a new technology is important step in the diversification of the company’s product offerings. Vanatta said the capability to license technology that would enhance manufacturers’ existing product lines provides additional incentive to consider a partnership with PureSpectrum.  

“What we are building is a series of pragmatic technological developments which correct what we understand to be recurring consumer complaints about the CFL bulb,” said Vanatta, who said the company plans to file a provisional patent application in the near future to protect the hybrid technology. “We want to aim our technology at directly addressing the demands of the consumers who will be using CFL bulbs. We believe what we are working on has the potential to make the CFL bulb more popular with consumers, ultimately leading to our manufacturing partners selling more bulbs.”
