Extech LT510 Light Meter
Lux is the unit measurement of illuminance and luminous emittance in the International System of Units (SI). One Lux (Latin for “light”) is the amount of illumination provided when one lumen is evenly distributed over an area of one square metre.
One foot-candle is equal to one lumen per square foot or approximately 10.764 Lux. In practical applications it is sufficient to think of one foot-candle as about ten lux as is typically done in the lighting industry.
