about 50,000 lumensAs a side note: A 400-watt HPS luminaire initially supplies about 50,000 lumens. The rule of thumb is to reduce the HPS lumen output by half to determine the LED lumen output, which would be 25,000 lumens in this case.
How high should HPS be?
HPS lights should not be placed inches from the plants, as you would place fluorescent lights; you should set HPS lamps higher, generally between 5 and 8 feet from the plants. Whether you have a reflector with your HPS light makes a difference for how close you can keep it from the plants.
