Don’t waste your time on Chinese lighting. I ordered (see photos) 3 full spectrum lights from BangGood (Chinese). Each one was a dismal fraction of it’s listed wattage. Using a PAR/LUX Meter each of these came in closer to “one zero less” than advertised. So; the 1200 Watt light was actually closer to 120 watts than 1200. Continue for each light. These are excellent for clones or seedlings, but they are insufficient for primary lighting.
