Footcandle fc is the amount of light flux density.
Fluorescent light lux calculation.
Footlambert fl is defined as the luminance of a surface reflecting transmitting or emitting one lumen lm of illumination per square foot of area in the direction being viewed or the conventional unit of brightness.
The total output of visible light from a light source is measured in lumens typically the more lumens a light fixture provides the brighter it is.
You can calculate lux from watts luminous efficacy and surface area.
Using the foot candle calculator.
It is the unit of measure used when describing the amount of light in a room and is expressed in lumens per square foot.
The amount of light that is cast on a surface is called illuminance which is measured in lux this can be thought of as light intensity within a specific area.
