Independent Testing Laboratories, the most experienced independent photometric testing lab in North America, was recently contracted by Hydrofarm to conduct independent testing on eight commercially available, competitive, double-ended horticultural lighting systems. Based on the test results generated by ITL, Hydrofarm’s Phantom Commercial Open Lighting System and the Phantom Commercial Enclosed Lighting System were ranked first and second place, respectively, in all five testing categories (relative efficiency, total µmol/s output, µmol/s per watt, absolute luminous flux and lumens/watt).
These test results mean the Phantom systems have now been scientifically proven to deliver higher PAR than the other leading systems tested. The Phantoms were proven to be more efficient and require fewer fixtures to deliver desired light levels. As a result, they are more cost-efficient than the other six fixtures in the testing group.
The independent photometric distribution testing, spectral analysis and efficiency testing provided by ITL Boulder was performed per the procedures and recommendations of the Illuminating Engineering Society of North America (IESNA). All testing was conducted on commercially available luminaires (units chosen at random from retailers’ stock to ensure they represented off-the-shelf quality and were not modified to enhance performance for testing).
