What is Lux?
Simply stated, the lux is the metric unit for measuring
the amount of light that falls on an object, and is the
European equivalent of the British foot-candle (or lumen).
Specifically, 1 lux equals the amount of light that falls
on a one-square-meter surface that is one meter away from
a single candle. 10 lux equals the amount of light produced
by 10 candles one meter away.
