Myth busting: Spectrum
Red, having the shortest wavelength of the visual spectrum, will saturate leaf surfaces. So there is a maximum amount of red that a plant will take. Yellow and Green have a bit more energy than Red, and so they are able to penetrate deeper into the leaf (in the case of red, orange, yellow), or deeper into the canopy (in the case of green, or far red), and excite chloroplasts lower down.
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.
