There isn't enough information there to answer the question. I doubt that it is what it is advertised to be, since it makes the claim that it pays for itself many times over every year in energy savings. I would take it seriously if it said, "provides 100 micromols per square meter per sec of PAR at a distance of 12 inches" or something comparable to that. Since it uses 225 LEDs they have to be very low wattage, low lumen output LEDs. If it used the currently available 1 watt LEDs it would cook the plants!
