GREEN ISLAND, NY -- March 21, 2013

Crystal IS, Inc., the leading manufacturer of proprietary, high-performance
ultraviolet light emitting diodes (UVC LEDs) for monitoring, purification, and
disinfection applications, has announced today that they achieved more than
65mW in optical output at 260 nm from a single UVC LED operated in a
continuous mode. The details of this breakthrough were recently published in
Applied Physics Express.

"This achievement is a technological milestone in the continued development of
brighter, more efficient and reliable UVC LEDs. By employing die thinning and
encapsulation techniques, we were able to increase the photon extraction
efficiency to over 15%, “said Leo Schowalter, founder and CTO. "By fabricating
our LEDs on our home grown aluminum nitride substrates, we continue to set the
pace of what is possible for the combination of highest efficiencies and
longest lifetimes in the 250-280 nm wavelength range, far surpassing diodes
fabricated on sapphire."

“This R&D accomplishment represents a more than 6-fold increase in performance
from just one year ago,” said Larry Felton, CEO. “Our progress in business
operations continues on a like pace, readying us and our LEDs for commercial
success.”

UVC refers to ultraviolet light with wavelengths between 200 – 280 nanometers
(nm). Light in the UVC wavelength can be used for disinfecting water,
sterilizing surfaces, destroying harmful micro-organisms in food products and
in air, and for spectroscopy applications. Yole Développement estimates the
UVC lamp market to be nearly $200 Million in 2012, with lamps being replaced
increasingly by UV LEDs.

"Our products will address some of the most pressing health concerns of our
time,” said Therese Jordan, Senior Vice President of Business Development. “We
are seeing demand in both water and air for the disinfection and quality
monitoring aspects of UVC. Similarly, spectroscopic instruments are also
taking advantage of the high light output available in a UVC LED. Unlike UV
lamps, UVC LEDs are mercury-free, compact, rugged and robust, lending
themselves to an array of designs and hold the promise of long life and
environmentally friendly end-of-life disposal.”

Engineering samples of UVC LEDs are available from Crystal IS.
