The ZELION HL300 are 100W - 600W tunable LED fixtures designed for all horticulture applications where supplemental lighting is required. These fixtures emit light in the photosynthetic active region of the visible light spectrum and can withstand the harsh environments of most modern production greenhouses over the life of the product. The optimized fixture design makes them easy to install and provides the smallest shadow footprint as compared to other fixtures in the same LED fixture class. The ZELION HL300 is the catalyst to achieve optimum photosynthesis for plant productivity and is an ideal replacement for 1000W HPS and Metal Halide systems. There are 3 fixture options available in addition to PC based Control Systems that allow for tuning and dimming of the fixtures.
