Record brand: Whiterose.<div style="font-size:14px;font-family:Roboto Regular;">Features:&nbsp;</div><div style="font-size:14px;font-family:Roboto Regular;">CMH&sup2;PS &nbsp;FULL SPECTRUM: We use 3500k white light &nbsp;as seedling and VEG spectrum (B:GY:R:FR=15%:45%:35%:2%), this spectrum is same as CMH/CDM on RGYB rate&nbsp;.&nbsp;When&nbsp;Flower Booster Switch ON, &nbsp;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 .&nbsp;Professional growers know that CMHCDM is great at the seedling&nbsp;and VEG&nbsp;stage, and HPS is able to ensure a very good harvest.High&nbsp;PPF&nbsp;efficiency&nbsp;Design: Our light get 2.7&micro;mol/J PPF efficacy even it&nbsp;get 50% R, and CMHCDM is 1.6&nbsp;&micro;mol/J, DE HPS is only 1.8&micro;mol/J.We use SANAN 2235 dual chip , it's chip area is almost twice the size of&nbsp;Samsung&nbsp;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 &nbsp;compare to old LED grow light.Uninterrupted&nbsp;Actual&nbsp;Planting&nbsp;Test: We set up some grow tents in our factory , we test our lights with pepper planting&nbsp;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&nbsp;20in&nbsp;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.&nbsp;It must be noted that if you want to get a good harvest, try to keep your&nbsp;grow room&nbsp;at a temperature between&nbsp;68&deg;F&nbsp;&nbsp;and&nbsp;86&deg;F&nbsp;, especially in winter, because the heat of LED light is &nbsp;low.MOST SAFE LIGHTS:&nbsp;Power drive is the core guarantee for long-term reliable operation of LED plant growth lamps. With many years of experience in LED power supply development, we know that the control device is in a low temperature and moisture proof state. It is a guarantee for stable and long life of the LED power supply, and it is also a guarantee to avoid fire when the power supply fails. Aluminum shell filling thermal adhesive is our standard for plant lamp power supply, which can meet the requirements of high humidity, high safety requirements and long working time.BEST SERVICE- We are a professional LED light manufacturer with strong R&amp;D team and many light tester. 3 years warranty plus 30 days money back guarantee.
