PureSpectrum Introduces True Dimmable CFL Bulb

PureSpectrum, Inc. announced that it has developed an electronic ballast circuitry design which enables Compact Fluorescent Lamps (CFL) 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 states that it 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 development allows for what is described as previously unattainable dimming capability and lighting control compatibility for CFL bulbs. In addition to enabling a CFL bulb to be dimmed to below 10% of perceived light output with a standard dimming switch, PureSpectrum’s circuitry design also allows a CFL to function side-by-side with incandescent bulbs and mimic performance characteristics such as low light starts.
