PureSpectrum Technology Makes True Dimmable CFL Bulb a Reality

Innovative Electronics Will Enable CFL Bulbs to Be Dimmed With Existing Lighting Controls

SAVANNAH, GA--(Marketwire - January 3, 2008) - Engineers from PureSpectrum, Inc. (PINKSHEETS: PSPM) have developed an electronic ballast circuitry design which enables Compact Fluorescent Lamps to be fully dimmable using a standard dimming device.

"This technology addresses a serious issue consumers have had with CFL bulbs, because this kind of functionality is not currently available for CFL bulbs," said PureSpectrum president and CEO Lee Vanatta. "We are continuing our trend of identifying needs within the marketplace and developing technology which provides a solution. During the past year, we have researched the limitations of CFL bulbs according to consumers and that data has shaped our development strategy."

PureSpectrum currently owns the rights to a family of patents and patent applications related to improved electronic ballast technology and circuitry designs for ballast driven lighting applications. In 2007, PureSpectrum Technology was able to confirm through independent testing that its ballast circuitry improves energy efficiency for linear fluorescent lamps and enhances multiple performance areas for CFL bulbs. PureSpectrum's proprietary ballast topology tested in CFL bulbs made by lighting manufacturing giants such as GE, Westinghouse and Sylvania produced sizable gains in both start time and run-up delay time while maintaining comparable energy efficiency.

The most recent engineering breakthrough allows for previously unattainable dimming capability and lighting control compatibility for CFL bulbs. In addition to enabling a CFL bulb to be dimmed to below 10 percent of perceived light output with a standard dimming switch, PureSpectrum's unique circuitry design also allows a CFL to function side-by-side with incandescent bulbs and mimic performance characteristics such as low light starts.

While most leading brand name lighting manufacturers include a dimmable CFL in their product lines, the popularity of these bulbs among consumers has been hindered by performance volatility and a prohibitively high price point. The bulbs often could not be dimmed lower than 20 percent of perceived light output and frequently did not function properly with existing lighting controls built to dim incandescent bulbs.

The high retail cost of dimmable CFL bulbs resulted from additional components in the bulb's electronics which enabled dimming to occur. In contrast, PureSpectrum's more efficient circuit topology will benefit both manufacturers and consumers.

PureSpectrum's ballast model has a component count similar to a standard non-dimmable CFL bulb and features high power factor built into the ballast. The reduced component count would increase manufacturing efficiencies and allow retail prices for dimmable bulbs to be in line with non-dimmable CFL bulbs.

PureSpectrum is currently conducting photometric testing on the initial dimmable prototype at leading lighting testing facility Intertek. The test results will include a performance comparison between the PureSpectrum prototype and dimmable CFL bulbs from MaxLite and GE.

"Our ballast uses a different circuit topology which will allow a CFL to dim just like a standard incandescent," said PureSpectrum director of engineering Ray King. "Furthermore, once this technology is introduced into the marketplace by a manufacturer, consumers will be able to place a CFL bulb in the same socket as an incandescent bulb and achieve the same dimming characteristics from very bright light to very low light. Our ballast can dim a CFL through the full range of light output, so we believe our technology will give end users an immediate option to purchase a truly dimmable CFL bulb."
