Roleadro LED Grow Light, Reflector-Series 600W Red Bule Full Spectrum Grow Lamp with Timer, Dual-Chip Plants Lamp for Hydroponic Indoor Plants Vegetative and Flower Reasonable Spectral Ratio and Upgraded Dual-Chip: 84 full-spectrum reflectors and 12 blue spectral reflectors form a reasonable spectrum. This design can ensure the most useful spectrum for plants growing in all stage and the blue spectrum can maximum the speed of leaves growing. 2 chips in each reflector for enhanced light intensity. White Flame-Retardant Plastic Case & 60 Reflector Cup: This light is made of a white flame-retardant casing, and the appearance is beautiful, generous and simple. It is safe and reliable in use. 60 reflector cup to perfectly reflect all dispersed light on plants, effectively reduces light loss compared to traditional lumen beads, and the illumination area and brightness level can be increased. Convenient Daisy Chain: 2-3 lights can be chained in a line, space saving and keep grow tent tidy, more convenient and safer in use. Efficient Heat Dissipation and Quiet: High-quality fans and aluminum heat sinks ensure efficient heat dissipation and extend life. The lower noise makes it not affect your life. Reliable Warranty and Professional Service: 12 months warranty and 30 days money back guarantee. Any questions, please email us, we will got a reply within 24 hours. We always stand behind and assist you. REFLECTOR CUP DESIGN: Maximizing diffusion light source within a scientific range. Ensure higher light intensity of uniform coverage on each plant, increase the efficiency of light and can promote growth, REASONABLE SPECTRAL RATIO: The wavelength type is rich, which coincides with the spectral range of plant photosynthesis and photomorphology; the spectral wave width is half-width narrow, and pure monochromatic light and composite spectrum can be obtained as needed; the light of a specific wavelength can be concentrated to illuminate the crop evenly. LESS HEAT: By using aluminum heats sink design to maximize heat dissipation area, the LED grow light maintains a cooler temperature even after 24 hours of continuous use. WIDE APPLICATION. Widely used in greenhouses, plant factory, greenhouse farming, flower farming, indoor gardens, water soluble breeding, pipeline cultivation, grow tent, farm, potted plants, tissue culture and so on. 1*600w Led Grow Light 1*Timer with Power Cord 1*Stainless steel hanger 1*Users Manual Product Dimension:   12.17* 8.44* 2.87 inch Product Weight:  2.43 lb LEDs QTY: 96*2 pcs Average Operating Power: 165W5% Ratio&amp;layout: Full Spectrum : Blue = 7 : 1 (Value spectrum to make plants thrive) Input Voltage: AC100-140V Working Current: 120mA/group Lifespan: 50,000 Hours CertificationsCE/RoHS Approved Working Temperature: -20to 40
