VividGro™ Indoor LED Grow-Light by Lighting Science® Anticipating Accelerated Growth of Cannabis Market Following Legalization in Six U.S. States

Demand for Cutting-Edge LED System Increased More Than 100 Percent in
12 Months

WEST WARWICK, R.I.–(BUSINESS WIRE)–#LED–With ballot results confirmed in three U.S. states for the recreational
use of marijuana, and three for medical use, the increased demand on
energy consumption in pro-cannabis territories is expected to skyrocket,
continuing the trend towards LED “grow light” solutions that curb energy
consumption and reduce energy costs to growers. Lighting
Science’s^® patented VividGro^™
LED lamp is proven to increase yields by up to 30% while using 45%
less energy. Today, the company announced that sales of their VividGro
LED indoor grow lights increased by more than 100 percent over the past
year alone. The cannabis industry is anticipated to jump from $6 billion
to $50 billion by 2026.

Since its introduction in 2015, VividGro has obtained rave reviews from
growers and distributors across North America, recently being named
One of the Top 5 Lighting Products by Marijuana Business Daily. With
the successful ballot initiatives to legalize the recreation use of, and
growing and manufacturing of marijuana in California, Nevada, and
Massachusetts, and with Florida, North Dakota and Arkansas approving
medical marijuana initiatives, the potential for energy saving
technologies are being embraced by the business and agriculture
community on an accelerated scale.

“Cannabis is one of the most energy-intensive industries in the world,”
said Pete Rumsey, Executive Vice President of Business Development at
Lighting Science. “Statistics show that one percent of all electricity
used in the United States today is used by indoor marijuana growers, to
the tune of almost $6 billion¹ annually. As the cannabis
industry continues to mature, grow facilities are increasingly turning
to LEDs to reduce energy costs and boost profits.”

LEDs Offer Energy Efficient Alternative to HIDs

Lighting Science was one of the first on the scene to offer an energy
efficient alternative to high-pressure sodium (HPS) lighting, which have
been draining the grid, as well as bank accounts. VividGro has been
particularly popular in the cannabis-friendly Pacific Northwest,
Michigan and Canada, where mom and pop grow facilities are quickly being
scaled up to lucrative multi-million-dollar business operations. A surge
in sales has been seen in the last six months, as the industry continues
to grow exponentially.

“We found that standard HPS lights were really cutting into our
profits,” said Ralph Sherman, a local grower of medical grade marijuana
in Oregon. “We literally couldn’t afford to keep the lights on. By
switching to LEDs we were able to cut our energy costs, increase plant
yields and even increase THC levels, which increased the value of the
product by 5 times.”

Sherman says the use of HPS lights aren’t just a financial concern, they
are having a real impact on the local grid. “We see PGE, the local
energy authority, struggling to meet the high demand. It’s causing real
problems. It’s nice to find a solution that is environmentally
innovative and that also helps our bottom line.”

About VividGro

Tailored to the indoor agriculture and horticultural markets, the
state-of-the-art VividGro product line delivers optimized
photosynthetically active radiation (PAR) to maximize plant growth and
PAR efficacy, while also providing light suitable for the human visual
system and excellent color penetration. VividGro’s patented light
spectrum has been proven to speed crop development and increase crop
yield. In addition, unlike other LED grow lights, VividGro distinguishes
itself from its industry peers by creating a “white light” working
environment for grow house employees. These commercial LED solutions are
highly adaptable to both urban and agricultural environments, including
greenhouses of any scale. Lighting Science continues to experiment with
the technology and spectrum to enhance the plant growth at different
stages and has plans to launch its next generation VividGro 3 in early
2017.
