For outdoor flood light fixtures, the Clear He Footcandle was the original measurement system for measuring light intensity on a square foot surface from a uniform light source. In other words, candlelight is a light that is one foot away from the candle. With human-centered lighting design principles in mind, IES, the largest association of professional lighting designers, provides recommendations on how many foot candles a human needs to perform different tasks and comfortably occupy various spaces.
For example, for dishwashing, they recommend that your lighting provide 20-foot candles 2 feet 6 inches from the floor. This is also called a horizontal target.
