Specification: 1. High lumen, high PAR, detailed data is above. 2. 60 90 120 degree lenses for your choice, maximum photosynthetic penetration from plant top to base, considerably increasing ¡°under canopy¡± production and yield 3. Bigger lighting area than other 3watt led grow light, detailed data is above 4. Lower noise and Lower temperature, we take the lower noise fan, which is specially designed for led grow. 5. Unique apperance design. Characteristics: 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 lower 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. Patented product, reaching UL GS standard. 10. Environment-friendly, no mercury and other harmful heavy metal, all material meet requirement of RoHS.
