1. Replace 3-5 times of HPSL power, 80% electric energy saving than tradition HPSL and MHL. 2. High lighting effect, 90% light will be absorbed by plant, but to the tradition HPSL and MHL, that light effect is just 8% - 10%. 3. These LED grow lights use only about half the electricity as HPS lights, and produce much more yield per watt. 4. Cooling system: Aluminum plate, quiet fan makes up better cooling system, one day later, that led grow light temperature is below than the same power in market. 5. The lighting area and the height are changeable according to different plants and environments, the same as the parameter 7. The unique appearance make it more exquisite and convenient to ship. 9.
