English term or phrase:foot candle power
The term "foot candle power" is a unit of power of electricity. Example: "20 to 30 foot candle power for service area". I am doing a Service Manual for a General Contractor. Any assistance would be very helpful.
Definition of Foot Candle
A "Foot Candle" is a standard unit, established as a reference and used when measuring the quantity of light. One Foot Candle equals the total intensity of light that falls upon a one square foot surface that is placed 1 foot away from a point source of light that equals 1 candle power. The term candela also refers to candle power, 1 candela = 1 candle power.
A light meter is used to measure the foot candle level of a scene. A light meter incorporates a photo-sensitive cell that creates an electrical current when light falls upon it. The metric reference for light level is known as Lux.
