300W LED Grow Light Full Spectrum Hydro Veg Flower Plant Medical Lamp Panel      High Cost-Effictive High Efficiency:Feature afford price with energy-saving. Save 90% energy compared traditional LED Light.Covers a full 2' x 2'/4' x 4' ,easily replace a 300W/600W while consuming 100/200 watts of actual power.Suitable for 100*100*180cm/120*120*200cm grow tent(not included).     New Upgraded LED chips:less heat release than other general grow light led's 1/3,High Par Value and High Lumen,Minimum Heat, Maximum Growth High par value(photosynthetically active radiation)ensured high light absorption of plants to maximize the plant growth and harvest. Higher lumen and long lifespan ensured.     Upgraded New generation PVC-steel Frame:lighter than other general led grow light panels,against friction, pressure,with long service life.high compressive strength and compression strength.Keeping heat off plants is essential.By using self-cooling aluminum and a unique heat sink design to maximize heat dissipation area, the LED maintains a cooler temperature even after 24 hours of continuous use.     Quality Parts-Not Jelly Bulit, Safe to use Light pass Strict quality standard. ETL, UL, CE, RoHS, SAA, PSE cetificate.Stronger hanging kits are available for easy installation. 100% Safe to use, zero risk no worry of fire or security threat,long-life.     Specifications: Chips Qty: 100 Pcs,  Color Spectrum: Red: 620-630nm; Blue: 460-470nm; White: 6000-6500K; IR: 725-730nm; UV: 390-400nm,  Blue LED can be absorbed better by Xanthophyll and Carotenoid so promote the Photosynthetic Efficiency, which is beneficial for the stem and leaf.  White LED improve the brightness and promote the photosynthesis.  UV with wavelength 380nm is good for seeding and sterilization.  IR is good for plant blooming.  View Angle of LEDs: 120 Degree Mixed,  Power Factor: >97%,  Recommended Coverage: 2.5x2ft(Veg) ,2x1.5ft (Bloom),  Recommended Height: Seeding: 24", Germination: (24-30)", Vegetative Stage: (18-24)" ,Flowering: (12-18)",  Recommended Lighting Times: Veg: 18h/6h(on/off) or 20h/4h(on/off) Flower:12h/12h(on/off),  Lumens: 5850lm,  Worldwide Voltage: 85V-265V,  Working Frequency: 50~60Hz,  Working Environment: -20~40℃ 45%~95%RH,  Material: Iron & Acrylic,  Color: White,  Charger: US/EU,     Features: 1.
