Most DE grow light manufacturers will tell you that a 5% failure rate is common and to be expected. In some cases that number reaches as high as 15%. Gorilla Commercial Lighting is proud to introduce a double-ended fixture that has been over-engineered using only the best components, meticulously manufactured with the tightest quality control standards allowing us to boast an amazingly low failure rate of less than 0.1%. The Gorilla DE Pro Series is more efficient resulting in higher PPF, and less heat than the leading competitor brands resulting in greater quality and yield for all of your grows. It can also run both HPS and CMH* bulbs. This all-in-one fixture utilizes a unique, low-frequency square wave design and optimized heat sinks, effectively increasing the lamp’s performance and making it the best grow light on the market today. The advanced design succeeds in lowering the considerable heat, acoustic resonance, and EMI produced by the leading high frequency, sine wave, DE competitors. *Use only with double arc tube style CMH bulbs.
