THE FOOT CANDLE
Unit of Illumination
A FOO'TiCAXTLE is the term used by scien-tist-s for the unit of illumination. Actually, it represents the light given by a eaiidle at a distance of one foot. In the average restaurant or public hall the degree of illumination should be round about 100 foot-candles, .while for a shop window the figure should 'be somewhere between 50 and 100.
Whether any place can be described as well lit or badly lit depends entirely upon the footcandles of the illumination. And how is one able to say just how many foot-candles the illumination of a street, a railway carriage, or a living-room represents’? Tne task is easy nowadays, for a tiny foot-candle meter has been invented which is carried easily in the pocket. This contrivance makes it possible to decide whether lighting anywhere is adequate or otherwise.
