New LED Lights Boost Greenhouse Production
Spectra Blade LED lighting from Intravision can boost the quality and quantity of indoor vegetable production. The lights are available in multiple lengths, spectrums and styles. They can be adjusted from 0 to 100 or 0 to 200 watts, can be passively or water-cooled, and can be adjusted in size from 4 to 12 pixels. The also come in single or double-sided models.
  “Our lights are being used in greenhouses, as well as in vertical farming and other controlled environments,” says Josh Siteman, Intravision. “We design turnkey systems tailored for specific plants and production facilities.”  
  The basic research for the LED’s is carried out in Norway, where company founder and CEO Per Aage Lysaa has been studying the impact of narrow bandwidth light on living organisms since 2000. The company’s LED systems offer up to 5 times the light intensity of the sun in a compact space.
  The company focuses on light spectrum quality that produces the best results for growers. Light recipes are developed in cooperation with the Controlled Environments Systems Research Facility at the University of Guelph in Canada.  
  “We know that plants have evolved under full spectrum light and that red and blue spectrum lights are the primary drivers of photosynthesis,” says Siteman. “Isolating the reds and blues conserves energy and allows leafy green crops to excel.”
  Tomatoes and strawberries require more complex systems, including ultra violet and infrared spectrums.
  Red light impacts quantity, making larger plants, while blue can affect taste, color and nutritional value. Founder Lysaa says LEDs have the potential to change taste and nutritional values based on the color combinations and intensity selected.
  The slim profile Spectra Blades range in length from 5-ft., 3-in. long to 7-ft., 10-in. While prices vary depending on options, a standard 6-ft., 10-in. light with digital drivers is priced at $550. A 5-ft., 3-in. single side, dimmable unit is priced at $280.
  Spectra Blades are available direct from the company, by themselves or as part of a structural design. In Canada, they are also distributed by Modular Farms (www.modularfarms.co) as lighting units by themselves. Modular Farms also markets a turnkey containerized vertical farm using Spectra Blades. Those units were designed and produced under Intravision supervision.
