At Hydrofarm, we value third party testing on our high performance horticultural light fixtures. The performance of our Phantom Photobio LED fixture line has been verified and validated by the leader in independent testing, Independent Testing Laboratories, Inc. (ITL). ITL is truly an independent test lab. It does not have ties to lighting manufacturers or specifying bodies. ITL has a reputation of producing test reports of the highest quality and accuracy. We think it’s important to give our customers independently confirmed performance data.
