WHAT LED is equivalent to 400W HPS?
As 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.
Is MH better than HPS?
In addition, HPS lights provide higher light intensity (lumens) than MH. This can be around 25-40% more lumens/watt than MH lights of the same wattage, and when it comes to flowering; the more light – the better the results.
How much does a 400W HPS yield?
Best marijuana yield indoors In theory, the math is simple. 400 watts of an HPS grow light could lead to 400 grams (14 ounces) of weed at the end of the day. 1200 watts would lead to 1.2 kilos (42 ounces) of marijuana, etc.
