(pronounced FUT KAN-dehl)

What an odd word, eh? Though it sounds like some kind of homeopathic healing method or a fetish one would find a website dedicated to, it is actually the term for a measurement of light level. A footcandle is standard unit of illuminance that is equivalent to the light intensity made by one candle at a distance of one foot. One footcandle produces a uniformly distributed flux of one lumen per square foot, which is written as lm/ft2. Very historical tech.
