PureSpectrum Introducing the First Dimmer Designed for CFL Bulbs

Truly Dimmable CFL Bulb Not Possible Before Creation of Two-Wire Dimming Device

SAVANNAH, GA--(Marketwire - January 30, 2008) - One of the most consistently damning complaints about Compact Fluorescent Light (CFL) bulbs among consumers has been that the bulbs cannot be dimmed, but engineers from PureSpectrum, Inc. (PINKSHEETS: PSPM) have developed a solution that will allow CFL bulbs to be dimmed just like incandescent bulbs.

As part of its market driven development model, PureSpectrum, Inc. engineered a fully dimmable CFL bulb and the first ever dimming device specifically engineered to operate a fully dimmable CFL bulb. The two-wire dimmer was recently used in independent testing conducted on PureSpectrum's dimmable CFL prototype and dimmable CFL bulbs made by GE and MaxLite.

Using the PureSpectrum dimming device enabled PureSpectrum's dimmable CFL to be dimmed in linear progression from 100 percent of perceived light output down to five percent. In contrast, the MaxLite bulb extinguished when power input was reduced to 60 percent and the GE bulb was unable to dim lower than about 40 percent.

While brand name manufacturers have promoted dimmable CFL bulbs in their product lines for years, a truly dimmable CFL bulb has never been manufactured. Consequently, there has never been a need for a dimming device designed to be compatible with a CFL bulb engineered to be truly dimmable. The supposedly dimmable CFL bulbs currently on the market have limited performance capacities, do not function well with existing dimming devices and fall well short of satisfying consumer standards.

The innovative PureSpectrum dimmer is a universal mechanism that is most effective when paired with PureSpectrum's CFL dimming ballast technology, but it will also operate incandescent bulbs and brand name dimmable CFL bulbs comparably to existing dimming devices. Additionally, the introduction of a fully dimmable CFL bulb and CFL dimming device would create opportunities for CFL bulbs to be used in residential and commercial retrofits as well as with new technologies such as daylight harvesting.

"The dimming device is critical, because true dimming capability would not be achievable for CFL bulbs without this dimming device," said PureSpectrum president and CEO Lee Vanatta. "With these technologies combined, there are virtually unlimited possibilities to diversify the application of CFL bulbs. Standard dimming devices for incandescent bulbs and the dimmable CFL bulbs sold today were never made to be compatible, resulting in the misconception that CFL bulbs cannot be dimmed. Our test results prove that CFL bulbs with the right ballast electronics and the right dimming device can be dimmed just like an incandescent bulb."

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 proprietary ballast topology produced sizable gains in both start time and illumination delay time while maintaining comparable energy efficiency in CFL bulbs made by lighting manufacturing giants such as GE, Westinghouse and Sylvania.
