Lighting Science of West Warwick, Rhode Island USA, has added a T8 LED grow lamp to its VividGro product line. The VividGro T8 grow lamp directly competes with a T8 grow lamp from Philips. The T8 lamp also brings the company into the vertical farming space.
Vertical farming grows crops in vertically-stacked layers, often indoors. The method carefully controls factors such as light, humidity, and nutrients to maximize crop output and quality. Although relatively new to the United States, vertical farming has already taken off in countries including England, Singapore, and Japan.
According to The Vertical Garden author Dr. Dickson Despommier, “The vertical farm concept is about maximizing plant density to enable large numbers of people living in the built environment access to healthy, fresh vegetables year-round that are herbicide and pesticide-free.”
Lighting Science says that the new T8 like other members of the VividGro product line, features high output, low heat radiation, and the firm’s patented grow spectrum. The T8 puts this performance into a flexible 4-foot linear design.
“Providing lighting solutions for indoor food crop production was a logical extension of our VividGro product line,” said Pete Rumsey, Executive Vice President of Business Development for Lighting Science. “Unlike traditional high-pressure sodium (HPS) and fluorescent lighting, our new VividGro T8 emits very little radiated heat and can be used in close proximity to the plant canopy. It provides the same micromoles that our VividGro PAR 38 is known for, but with a thin profile that makes it a real problem-solver for vertical farming space constraints.”
Since its introduction in 2015, Lighting Science’s VividGro product line has provided growers a low-cost and energy-efficient alternative to fluorescent and high-pressure sodium (HPS) grow lights. According to Rumsey, the new VividGro T8 uses about 50 percent less energy and lasts about ten times longer ( an L70 of 50,000 hours) than comparable fluorescents, which typically require replacement every 8-10 months.
Lighting Science asserts that VividGro’s proprietary spectrum technology also ensures that plants receive the ideal levels of (photosynthetic photon flux) PPFD at each stage of growth. Research conducted by the University of Guelph showed that VividGro’s light spectrum accelerates the photosynthetic process, increased the nutritional density of crops by 10-12 percent, and improved crop yield by up to 30 percent.
The ballast bypass design of the VividGro T8 gives indoor horticulturists significant flexibility. The lamp can be hung individually, either vertically or horizontally, and with single-ended connectors. Also, the VividGro T8 can be installed in 1, 2, 3, 4 and 6 lamp, 4-foot troffers and can be hung in a direct wire troffer combo.
Lighting Science says that its new VividGro T8 is suitable for indoor commercial growers and do-it-yourself horticulturalists and is also adaptable to both agricultural and urban environments, including greenhouses of any size.
Lighting Science intends to introduce its next generation VividGro 3 later in 2017.
