The inverse square law
Every time you double the distance between your plant and its light source, the power it receives is quartered. One of the benefits of LEDs is that they are relatively cool, so you can move them closer to the plants.
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.
