Lux
A standard of illumination, q. v., as distinguished from illuminating
power.
It is the light given by one candle at a distance of 12.7 inches–by a
carcel, q. v., at a distance of one meter—or by 10,000 candles at
105.8 feet.
It was proposed by W. H. Preece. All the above valuations are identical.
