/ CORRECTION - Independent Testing Confirms High Power Factor Rating for PureSpectrum's Dimmable Electronic Ballast

SAVANNAH, GA, Jul 23 (MARKET WIRE) --
In the news release, "Independent Testing Confirms High Power Factor
Rating for PureSpectrum's Dimmable Electronic Ballast Technology," issued
earlier today by PureSpectrum, Inc. (PINKSHEETS: PSPM), we are advised by
the company that the second sentence of the secnd paragraph should read
"A perfect Power Factor rating is 1.0, and PureSpectrum's dimmable CFL
ballast technology rated .974 in independent testing performed at a
NVLAP-certified facility at the request of multiple prospective licensing
partners" rather than "A perfect Power Factor rating is 1.0, and
PureSpectrum's dimmable CFL ballast technology rated .0974 in independent
testing performed at a NVLAP-certified facility at the request of
multiple prospective licensing partners" as originally issued. Complete
corrected text follows.

Independent Testing Confirms High Power Factor Rating for PureSpectrum's
Dimmable Electronic Ballast Technology

Technology Addresses Important but Often Overlooked Performance
Characteristic That Could Save Money for Consumers

SAVANNAH, GA -- July 23, 2008 -- PureSpectrum, Inc. (PINKSHEETS: PSPM) has
confirmed through independent testing that the company's proprietary
dimmable ballast technology for Compact Fluorescent Light (CFL) bulbs
rates extremely high in a critical performance area called Power Factor.

Power Factor is a complicated mathematical formula which measures power
quality that is currently unfamiliar to most people, but the ramifications
of this ratio will soon become a high priority in every household in the
United States. A perfect Power Factor rating is 1.0, and PureSpectrum's
dimmable CFL ballast technology rated .974 in independent testing
performed at a NVLAP-certified facility at the request of multiple
prospective licensing partners.

As the incandescent bulb, the primary residential light bulb for more than
100 years, is replaced en masse during the next four years as the 2007
Energy Bill goes into effect, consumers may be surprised to learn that
using energy efficient CFL bulbs with low Power Factor could cause
household energy bills to rise. While CFL bulbs are considerably more
energy efficient than incandescent bulbs, CFL bulbs draw electricity
differently than incandescent bulbs and harmonic distortion created by
electronic ballasts in CFL bulbs can result in harmonic distortion.

Harmonic distortion reduces power quality, and this energy imbalance can
lead to extensive and expensive corrective actions by utility companies.
Furthermore, there has never been a study of the effects of Power Factor
on lighting in the U.S., and with a variety of CFL bulbs with varying
Power Factor ratings being introduced and installed industry experts are
not able to accurately predict the total cost or effect of low Power
Factor CFL bulbs.

"There is no reliable data to represent the final impact that Power Factor
will have on the fluorescent lighting market, but it will certainly be a
competitive advantage for any manufacturer to be able to offer a CFL
product with high Power Factor," said PureSpectrum president and CEO Lee
Vanatta. "We recognize that Power Factor is going to be tremendously
important part of the equation for the lighting industry as lighting
manufacturers and utility companies begin to digest the scope of the
transition that is about to occur. Our research has made us aware the
widespread use of low Power Factor CFL bulbs during the next few years
will damage power quality and result in expensive corrective procedures
for the utility companies and that expense will be passed on to the
consumer.

"We have seen one study that estimated the cost of power factor correction
to be as much as $4 for every 20-watt CFL that is installed," Vanatta
added.

Most brand name CFL bulbs currently on the market in the U.S. have low or
poor Power Factor ratings, and recent research has concluded that the mass
introduction of low power factor CFL bulbs would result in a costly
degradation of power quality. That cost will ultimately be passed along to
the consumer by the utility companies through the introduction of new
meters which measure not only usage but also power factor.

In non-residential settings where fluorescent lights have long been the
standard, utility companies already assess customers for power factor
correction. Lighting industry experts expect a similar power factor
correction penalty to be added to residential energy bills in the future
to offset the "dirty" or unproductive power created by the influx of
millions of low Power Factor CFL bulbs.

Through exhaustive market research during the development of its
technology, PureSpectrum identified performance areas for CFL bulbs which
would need to be addressed by manufacturers in order to accelerate the
widespread consumer adoption of CFL bulbs. Additionally, according to
Vanatta, the company's advance technology engineered ballast technology
that would also address inevitable criticisms such as low power factor.

"From inception, PureSpectrum has consistently stated that we are
developing lighting technology to satisfy the needs of both manufacturers
and end users, and the integration of our ballast into a CFL product line
would enable manufacturers to increase consumer satisfaction," Vanatta
said. "We understand that the lighting industry will be experiencing
substantial upheaval during the next few years, and we also see the big
picture for lighting manufacturers trying to satisfy the demand for more
energy efficiency while also satisfying customers. Our ballast circuitry
represents an immediate solution that addresses all of the foreseeable
problems associated with switching out billions of light bulbs at one
time."
