As the recognized technical and educational authority on illumination,
IES annually announces significant new advancements in lighting
products, research, publications, and design tools in its IES Progress
Report. Acceptance is based on an impartial judging process used by the
committee to evaluate each submission on its uniqueness, innovation and
significance to the lighting industry.

SunLike Series natural spectrum LEDs are the world's first LEDs to
produce light that closely matches the spectrum of natural sunlight,
delivering human centric lighting that lowers the blue light peak common
in conventional LEDs. They deliver light that eases eye strain, helps
maintain stable human circadian rhythms, and enhances the color clarity
of objects. Introduced in June 2017, the SunLike Series natural spectrum
LEDs are an advanced light source that combine the latest optical and
compound semiconductor technology of Seoul Semiconductor with Toshiba
Materials' TRI-R® technology to produce light that closely
matches the spectrum of natural sunlight.

According to the results of a study done by the Bio-Information
Laboratory of Seoul National University Hospital in July of 2018,
SunLike Series natural spectrum LEDs have been shown to reduce eye
discomfort and improve sleep patterns. Seoul Semiconductor's SunLike
Series LEDs have been adopted by premium lighting brands in Korea, US,
Europe, China, and Japan to deliver high value human centric lighting
for home lighting, smart desk stands and lamps, offices, hotels, and
public facilities.

In addition, the SunLike Series LEDs are the only 25W single light
source in the world to receive RG-1 level Eye Safety Certification from
the Korea Testing & Research Institute last November. This is the safety
level given to light sources with no photobiological hazards.

"It is an honor for the SunLike Series natural spectrum LEDs, powered by
TRI-R, to be recognized in the 2018 IES Progress Report as one of the
significant developments in the art and science of lighting, validating
our focus on the development of high performance, value added LED
technology," said MinSu Son, marketing vice president of Seoul

"The demand for human centric lighting continues to rise as experts
agree on the importance of quality light for human health," added Son.
"We developed the SunLike Series LEDs to provide lighting designers and
engineers with true natural spectrum LEDs that not only minimizes the
negative health effects of artificial light, but actively enhances the
overall lighting experience."

In May, SunLike Series LEDs were recognized with a 2018 Edison Award
from the influential lighting industry news site EdisonReport as
one of the "Top 10 MUST SEE Products" at the 2018 Lightfair
International conference. In addition, SunLike Series LEDs received the
Gold Award as a Product of the Year from the German electronics industry
magazine, Electronik, in March of this year.
