Fluorescent light lux calculation.
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.
Use the light table to find out how many lux or footcandles you need.
Watt and lux units represent different quantities so you can t convert watts to lux.

Footcandle fc is the amount of light flux density.
Choose the area of the house that you want to illuminate.
For the whole kitchen it is 108 lux and for the counter detailed tasks 538 lux.
Watts to lux calculation with area in square feet watts to lux calculation with area in square meters.
Multiply the area in square meters by the lux or the area in square feet by the footcandles.
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.
Check the optimal lighting level.
You can calculate lux from watts luminous efficacy and surface area.
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.
