About Lumens Per Square Foot Calculator (Formula)
The Lumens Per Square Foot (LPSF) Calculator uses the following formula to calculate the luminous intensity or brightness of a space:
LPSF=TL/A
Where:
- LPSF represents the luminous intensity per square foot, measured in lumens per square foot (lm/ft²).
- Total Lumens (TL) is the total amount of light emitted by a light source, measured in lumens (lm).
- Area (A) refers to the total surface area of the space in square feet (ft²).
This formula allows you to assess the brightness of a space in terms of the amount of light available per unit of area. It is a critical metric for determining suitable lighting levels for various environments, such as offices, homes, or commercial spaces, ensuring adequate illumination for tasks and activities.
