Lighting control systems in refrigerated cold spaces are more capable now than ever, says Tim Stevens, product manager, Kenall Manufacturing, Kenosha, Wis.
“Analytics and area utilization heat mapping are gaining traction among building owners by providing a better understanding of inactive areas within a facility, bringing savings and efficiency to this expensive real estate,” he adds.
Kenall Manufacturing’s EnviroPro IMP Sealed Top Access LED Luminaire for insulated metal panel (IMP) ceilings is said to reduce IMP ceiling cutout by 40% while protecting the integrity of IMP ceilings. And, the new version is compatible with a wide variety of previous installations where old lamp technology is in place, and boasts a DLC certification, making it suitable for energy rebate programs.
“Fixtures for this industry have improved so greatly that nobody should still be using fixtures more than five years old,” Stevens adds. “The energy savings and rebates have, for some of our customers, paid for the new fixtures before the first year.”
For its part, LumiGrow lighting solutions integrate with a number of smart controls, sensors and cloud-based technology, according to Brandon Newkirk, director of marketing for the Emeryville, Calif.-based company.
For instance, smartPAR, its cloud-based wireless control system, allows growers to adjust light spectrum, intensity and photoperiod of their lights to improve crop production. Plus, smartPAR features a lighting and energy management dashboard that displays lighting analytics, and integrates with the company’s light sensors to read sunlight and use predictive analytics to achieve an ideal lighting environment in greenhouses.
LumiGrow also launched BarLight smart LED grow lights for high-density cultivation in the vertical growing cannabis market. LumiGrow TopLight Hybrid is a smart LED toplight for greenhouse and high-bay applications. And, LumiGrow SporeCam captures, inspects and classifies harmful airborne spores for diseases to optimize disease management practices, minimize yield losses and monitor the effectiveness of their treatments.
“As a whole, LED grow lights have become much more efficient, and are becoming the preferred lighting solutions for commercial horticulture applications,” Newkirk says. “Modern LED grow light technology is built to such a higher quality and efficiency than HPS lighting strategies that we will continue to see growers making the business case for removing their older lighting technology for high-tech lighting solutions that can help them remain profitable in an increasingly competitive market.”
