Fluorescent light lux calculation.

It is the unit of measure used when describing the amount of light in a room and is expressed in lumens per square foot. Choose the area of the house that you want to illuminate.

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.

Work out how many bulbs you need. Watt and lux units represent different quantities so you can t convert watts to lux. Calculate the amount of lumens you need. Check the optimal lighting level.

Use the light table to find out how many lux or footcandles you need. Multiply the area in square meters by the lux or the area in square feet by the footcandles.

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. Using the foot candle calculator. 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.
