Light Output Information
What is Footcandles/LUX
Foot-candle and lux are units for measuring illuminance—the amount of light that reaches a specific area, and at a specific distance. The difference being that foot-candle (fc) is a U.S. Customary/British Imperial unit, whereas lux (lx) is an SI (metric) unit. As a result, one foot-candle is equal to one lumen per square foot, and one lux is equal to one lumen per square meter.
