SP1000 LED Grow Lights achieve a high energy efficiency of 2.7 umol/J and improve the light transmittance. The LED Growing Lights consume only 120W of power, which assures a 60% more return than the old HPS/MH lights and saves up to 70% more energy than other led grow lights. Veg Coverage: 3.5x3.5 ft, Flower: 3x3 ft. Full-spectrum Sunlike Lighting: These LEDs deliver optimal light-spectrum coverage (660nm, 730nm, 3000K, 5000K), offering more power for your blooms and maximum PAR output at various distances; The cool white light (5000K) promotes germination rates, the warm white light (3000K) peeds up blooming time, and the red light (660nm) improves the plant production; The lights can get through the surface of plants and deep into them to increase yields. Quiet & Durable: SP1000 3x3 grow light is designed with a high reflective and noise-free fanless professional LED grow system.
