Quality of light is very important in the workplace, schools, greenhouses and public buildings. Too little light (or luminous intentsity) affects the quantity and quality of performance of both people and crops. HANNA's light meter uses special optic filters to mathc the spectral sensitivity of the human eye.
Luminous intensity is measured and reported in foot-candle or lux (lx). Light meters are commonly referred to as lux meters. One lux is equal to one lumen per square meter and one foot-candle is equal to one lumen per square root.
foot-candle = 10.764 lux
lux = 0.0929 foot-candle
