Myth busting: Lumens
A local competitor has started claiming that their products achieve 200-800lm/W. This is nonsense. Maximum luminous efficacy is based on a definition of 683lm/W being the maximum possible, for monochromatic light with wavelength 555nm (green) - i.e. the peak of the human visual spectrum.
UV causes plants to produce oils, antioxidant vitamins and flavonoids to protect themselves from the damaging effects of UV. These compounds produce the vibrant colors, smells and tastes of plants.

How many watts do I need per square foot of grow space?
You will want around 30-40 watts of actual wattage per square foot of grow space. Some LED grow lights require less, while others require more depending on the efficiency. It is best to follow the manufacturer's recommendation because all LED units are designed differently. See this article to learn more.
You shouldn't actually use wattage to determine how powerful of an LED grow light you need. Instead there are other factors that are more important, such as PPFD and footprint uniformity.
