Soraa Introduces GaN on GaN LED-based MR16 Lamp

Soraa, which was founded by Shuji Nakamura and Steve DenBaars, announced the
launch of its flagship product, the Soraa LED MR16 lamp. Soraa claims that new
replacement lamp is the first single-LED design to provide illumination equivalent
to a 50-watt halogen MR16. Pricing was not announced, but is intended to provide
a retrofit payback of routinely less than 1 year in standard commercial usage.
Soraa says that its flagship product, the LED MR16 lamp based on GaN on GaN
technology represents a revolutionary lighting technology hence the moniker,
LED 2.0.

Soraa reportedly leverages decades of expertise from the two GaN LED lighting
innovators who have done much of their research work during the last decade
at the University of California, Santa Barbara. The company is headquartered
in Fremont, California, where it houses the world’s first GaN on GaN light-chip
fabrication facility and their lighting products design lab. Soraa claims that
its pure GaN crystal is up to one thousand times purer than GaN on sapphire
or GaN on silicon carbide substrates, allowing both the power density of the
chip to be increased, and the chip size to be substantially reduced compared
to standard LED devices.

“Our technological foundation enables Soraa products to emit more light
per LED material and handle more electric current per area than competitors,
providing the highest quality light that makes for a perfect, more energy efficient
replacement for traditional halogen lamps,”
said Soraa CEO Eric Kim. Soraa
says it chose the MR16 format because it has been the most difficult LED lamp
to do correctly, given its small size and intense, high quality brightness requirements.
Khosla Ventures, NEA Partners, and NGEN Partners are backing Soraa with over
$100 million in funding.

Luxeon High Power

Soraa’s MR16 LED lamp offers what the company describes as a bright, highly-focused,
controlled beam with the ability to produce a high color rendering index and
center beam candle-power to match a standard halogen lamp. An efficient thermal
design does not require a mechanical fan or other active cooling, and the form
factor is fully conformant to the MR-16 envelope. In addition, the lamp’s single-source
LED design offers crisp object definition with solo shadow, uniform color and
beam pattern. Additionally, the Soraa LED MR16 lamp features optimized electrical
design for broad compatibility, making it suitable for use with all common transformers
and dimmers, both indoors and outdoors.

“Lighting affects the way we see the world, and good light can make anything more compelling,” said Co-Founder Shuji Nakamura. “At Soraa, we are proud to create efficient lighting products that do not compromise on performance, offer the highest quality available, and greatly reduce energy waste. We believe that with GaN on GaN, we have truly entered the next chapter in LED technology: LED 2.0.”
