Light Net Weight: 3.2kg , 7lbs. Light Dimension(inch): 23.6(L)x14.2(W)X4(H). CMH²PS FULL SPECTRUM: We use 3500k white light as seedling and VEG spectrum (B:GY:R:FR=15%:45%:35%:2%), this spectrum is same as CMH/CDM on RGYB rate. When Flower Booster Switch ON, this spectrum(B:GY:R:FR=12%:30%:48%:8%) get more red and far-red light , this spectrum is same as HPS on RGYB rate. Professional growers know that CMHCDM is great at the seedling and VEG stage, and HPS is able to ensure a very good harvest.High PPF efficiency Design: Our light get 2.7µmol/J PPF efficacy even it get 50% R, and CMHCDM is 1.6 µmol/J, DE HPS is only 1.8µmol/J. We use SANAN 2235 dual chip , its chip area is almost twice the size of Samsung LM301B, and consume only 240W with 576 LEDs , and we use only 1% light decay nano-waterproof coating. All of these will let grower get 40% higher yield compare to old LED grow light. Uninterrupted Actual Planting Test: We set up some grow tents in our factory , we test our lights with pepper planting from germination to fruit. Using CMH and DE HPS to grow together , constantly adjust spectrum and efficacy with our led light , try to design best led grow light. FOOTPRINT : In veg stage , 4X4ft just need 2pcs this lights , hanging 20in from the plant. In Flower stage, 4X4ft need 2-3pcs this lights , hanging 20in from the plant, and the harvest will very cost to best 1000W HPS. It must be noted that if you want to get a good harvest, try to keep your grow room at a temperature between 68°F and 86°F , especially in winter, because the heat of LED light is low.
