I bought this light not expecting much after testing the PAR output of a blurple light. I tested this light as well as a 600watt hps. This 200w light really does give more umol/(m^2/s) than a 600watt HPS in the usable area. The 600watt HPS has a larger cover area, the effective coverage of this light is 2x2. Outside of that, your plants get almost nothing. Inside of that, you get as much light as your plant can theoretically ever handle.
I've used 600w HPS for a long time and had not found any LED lamps that were really comparable, but this one is. You would need 4 of them to effectively fill a 4x4, though.
