PRESS RELEASE

David Friedman to Lead Lighting Science^® Horticulture Division

WEST WARWICK, R.I.–(BUSINESS WIRE)–Lighting Science announces the appointment of David Friedman as President of VividGro^®, the horticultural division of Lighting Science Group Corporation, a leader in advanced applications of LED technology. Lighting Science’s mission is to bring life-changing products in human health, agriculture, and infrastructure to market. Their extensive technology and intellectual property portfolio includes nearly 400 LED technology patents, from biological circadian LED technology solutions to VividGro’s expanding range of products for cannabis and indoor agriculture.

Friedman is no stranger to the cannabis industry. An industry veteran and experienced venture capitalist, he founded Panther Funds in 2014, which has invested in 20 cannabis companies. He is also the former CEO of MJIC, which was initially a venture fund for the cannabis space. Friedman successfully managed the company’s restructuring in 2015/2016 into a diversified operating company in the cannabis space and co-created the current algorithm for the MJIC Marijuana Stock Index. MJIC is expected to IPO on the ASX in August of 2017. His background also includes 25 years as an investment and operating executive in venture capital, mergers & acquisitions and corporate finance.

“It’s a privilege to be able to lead such an experienced and accomplished team,” said Friedman. “The years of research and development, strong investment partners and product acceptance in the market are unique in the nascent cannabis space. The commitment by LSGC to dedicate these resources to the VividGro division validates the tremendous opportunity our industry represents.”

Lighting Science has long been investing in the research and development of urban agriculture, including working with NASA for almost a decade and the U.S. Scientific Research Station to establish indoor food production at the South Pole. Since establishing VividGro in 2014, LSG’s offerings have remained one of the most popular products in cannabis and large-scale indoor farming production. Lighting Science was one of the first LED companies to offer an energy efficient alternative to high pressure sodium (HPS) lighting. Their patented VividGro LED lamp is proven to increase yields by up to 20% while using 45% less energy. In addition, unlike other LED grow lights, VividGro distinguishes itself 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.

The VividGro team will be led by Friedman and Emil Radkov, a veteran of the horticultural lighting industry. Backing them up are a team of scientists and sales and marketing executives who all have lighting industry and cannabis industry experience. Friedman will be expanding the team over the coming months as they look to continue their aggressive growth strategy.
