Full Spectrum 300W Dimmable LED Grow Light Red/Blue/White/UV/IR For Hydroponics Indoor Outdoor Greenhouse Grow Tent Plants Grow Input:AC220V or AC110V 50/60HZ Power:300W, Dimension: 210*190*30mm, Net weight: 480g , Lifespan: 50000hours Working Temperature: -20 to 40 Degree Celsius View Angle: 120 degree Lighting Coverage:1.6 – 13 square meters Recommended Height: 0.3 m- 2 m Actual power consumption:30-35W ; Recommended Coverage:One COB for 1-3 square meters, Spectrum:380-840nm Is Dimming: Yes Waterproof：IP65 NOTE：We use the insulated heat conducting shim isolated from the outer shell and chip, resistant to high voltage 4KV, safe and reliable. Package include: 1 x led grow light 1 x messenger wire Recommended Lighting Time: Vegetative Stage: 14-18 hours on. Flowering Stage:10-12hours on. Fruit stage:6-10hours on. Waterproof grade: IP65,Not only indoor gardens and greenhouses use but also for outdoor vegetables use. Highlights: 2 Modes of use, not only can use the hanging kit to hang it and Irradiate plants from the top side, also can be used as a spot light/floodlight projects from the lateral side. Notice: UV IR likes dark and deep,that is normal.they are important for your plant… It is hard to see the lights of the IR led clearly by eyes.Please don’t think it is not working. Instead, it plays an very important role in the flowering and fruiting stages of plants. Features: Optimum YIELDS—Optimized Driving Current Increases Diode Efficiency and Output, Resulting in a Brighter, Higher Yielding Footprint Optimum SPECTRUM—Proprietary 12 Band Complete “Perfect Full Spectrum” including both IR & UV diodes. Optimum INTENSITY—Optical lens lens and Increases Irradiation area, as well as Canopy Penetration By Up to 200% Optimum Optimum heat dissipation —The use of ultra-thin aluminum shell convection cooling structure to heat, no need to add motor fans to dissipate heat, no noise, reduce the failure rate; weight is very light, easy for installation, more secure. Optimum Lamp life —Integrated intelligent IC driver, without external drive power supply, reduce the failure rate caused by power supply, compatible with SCR dimming, lamps more longer life.
