Enter the room area in square feet and the lumens per square foot into the calculator to determine the total lumens needed for a room. This calculator helps in planning the lighting requirements for a space.
Lumens Per Room Formula
The following formula is used to calculate the total lumens needed for a room.
TL = A * LSF
Variables:
- TL is the total lumens needed for the room
- A is the room area in square feet
- LSF is the lumens per square foot, which varies based on the room type and desired brightness
To calculate the total lumens needed for a room, multiply the room area by the lumens per square foot.
What are Lumens?
Lumens measure the total amount of visible light emitted by a source. The higher the lumens, the brighter the light. When planning for lighting in a room, considering the lumens is important to ensure the space is well-lit according to its use. Different activities and room types require different levels of brightness, which is why lumens per square foot can vary.
How to Calculate Total Lumens Needed for a Room?
The following steps outline how to calculate the total lumens needed for a room.
- First, determine the room area (A) in square feet.
- Next, determine the lumens per square foot (LSF) based on the room type and desired brightness.
- Use the formula from above = TL = A * LSF.
- Finally, calculate the total lumens (TL) needed for the room.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Room area (A) = 150 square feet
Lumens per square foot (LSF) = 50 lumens per square foot
