PureSpectrum, Inc. Has Perfected Technology That Will Enable First Fully Dimmable CFL

Newly Developed Ballast Circuitry Represents First Truly Dimmable CFL bulb

SAVANNAH, GA--(Marketwire - January 29, 2008) - Independent testing has confirmed that PureSpectrum, Inc. (PINKSHEETS: PSPM) has developed ballast technology that will allow lamp manufacturers to produce a fully dimmable CFL bulb that will perform better and cost less to manufacture than any commercially available dimmable CFL bulb.

In photometric tests conducted at a NVLAP-certified laboratory in Colorado, a PureSpectrum prototype was dimmed at five percent increments from 100 percent of perceived light output down to below 10 percent. At every interval, the prototype functioned without interruption and showed no signs of instability.

The PureSpectrum prototype was tested against market-leading dimmable CFL bulbs made by GE and MaxLite. Neither brand name bulb dimmed in proportion to power input, the MaxLite extinguished at 60 percent of perceived light out while the GE extinguished at around 40 percent of perceived light output. The PureSpectrum prototype continued to operate through the full range of light output (see inset chart).

The tests were performed using a two-wire dimmer specially developed by PureSpectrum's engineering team to be compatible with a fully dimmable CFL bulb. When PureSpectrum began development of its dimmable CFL bulb, it was quickly discovered that there was not a commercially available dimmer which was built to work with a truly dimmable CFL bulb.

"In many ways, we started from scratch and created something that did not exist before we began work on this project," said PureSpectrum president and CEO Lee Vanatta. "It is not an overstatement to say that this is one of the most important breakthroughs in the history of the development of CFL bulbs. We have basically created the technological gateway to the first and only truly dimmable CFL bulb that functions the way a consumer would expect a dimmable bulb to function."

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. In addition to the performance benefits gained through PureSpectrum Technology, the PureSpectrum ballast model contains only 25 electronic components compared to 69 parts for the GE dimmable CFL and 30 parts for the MaxLite dimmable bulb. The lower component count should allow manufacturers to build the bulbs for a lower cost and drastically reduce the cost of dimmable CFL bulbs.

"The two major impediments to the growth of the CFL market have been an instant-on capability and the inability for CFLs to dim," said lighting industry expert David Gordon, president of Channel Marketing Group. "Dimmable CFL bulbs have consistently underperformed and have been too expensive to be consumer friendly. There is no question that PureSpectrum's technologies for CFL bulbs will accelerate CFL sales once the technologies are integrated into lamp manufacturer's product lines."

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.
