FREMONT, Calif., 2013-05-16 18:08 CEST (GLOBE NEWSWIRE) --
Removing barriers to the widespread adoption of LED lighting, Soraa announced
today 230V GU10 and 100V E11 versions of its new perfect spectrum SORAA VIVID 2
and PREMIUM 2 LED MR16 lamps—the first ultra-efficient replacements for 65-watt
and 75-watt halogen lamps. A technological breakthrough made possible by
Soraa's world-record performance gallium-nitride on gallium-nitride (GaN on
GaN™) LEDs, the new SORAA LED MR16 lamps deliver the industry's highest light
output, while rendering vivid colors, richer reds and whiter whites,
transforming ordinary lighting in any space into extraordinarily vibrant,
brilliant and energy efficient lighting. Today's announcement comes on the
heels of Soraa's new lamp line availability announcement for the North American
market.

"The SORAA VIVID 2 and PREMIUM 2 lamp lines represent a tipping point in the
widespread adoption of LED MR16 lamps — we now have 65-watt to 75-watt
equivalent lamps that produce full visible spectrum light and consume 80% to
85% less energy," said Dr. Tom Caulfield, President and COO of Soraa. "And
what's amazing is that we have just scratched the surface in terms of
performance gains from our GaN on GaN LED technology. Look out halogens — your
days are numbered." 

Most LED lamps available today are based on LEDs made by depositing GaN on
foreign substrates like sapphire, silicon carbide or silicon. Consequently,
these LEDs have high crystal defect densities that limit the amount of current
densities they can handle, thereby limiting the amount of light they emit per
unit area. These high defect densities also constrain the LEDs to much lower
temperatures in order to operate reliably. Both these limitations are amplified
when these LEDs are used in a small form factor like an MR16 lamp, which is
frequently installed in constrained or enclosed fixtures, and is used in
applications that require very high light output. The lamps that use these LEDs
have to make compensating design choices like using multiple LED light sources
to generate the required amount of light, and active cooling mechanisms to keep
the LEDs within their operating temperature range. 

In contrast, the SORAA VIVID 2 and PREMIUM 2 lamps' GaN on GaN LED technology
leverages the 1000x lower crystal defect density advantage of the native
substrate, thus emitting substantially more light and allowing reliable
operation at much higher temperatures. This enables a very simple and robust
MR16 lamp design that uses a single LED light source and a simple heatsink,
while producing 65W to 75W halogen equivalent light output and operating
reliably at lamp temperatures of up to 120°C, a requirement for use in the most
constrained fixtures. 

"I believe the SORAA VIVID 2 and PREMIUM 2 lamp lines will have a profound
effect on lighting design — smaller-form-factor, high-output LED MR16 lamps
will now replace larger lamp types like PARs," added Dr. Caulfield. 

The SORAA VIVID 2 LED MR16 lamp has a CRI of 95 and R9 of 95 and is available
in a complete suite of beam angles, color temperatures and lumen outputs; and
the SORAA PREMIUM 2 LED MR16 lamp has a CRI of 80 and is available in multiple
beam angles and color temperatures. 

Experience the SORAA VIVID 2 and PREMIUM 2 LED MR16 lamps at Soraa's booth
(#P72) at The ARC Show in London, UK on May 19-21. For more information on all

About Soraa

Pioneering lamps using LEDs built from pure gallium nitride substrates (GaN on
GaN™), Soraa has made ordinary lighting extraordinarily brilliant and
efficient. Soraa's full spectrum GaN on GaN™ LED lamps have superior color
rendering and beam characteristics compared to lamps using LEDs created from
non-native substrates. Founded in 2008, Soraa is located in Fremont California,
where it manufactures its GaN on GaN™ LEDs in the company's state-of-the-art
facility. For additional information, please visit www.soraa.com.
