Lumens per Room Calculator

Formula

The formula to calculate the total lumens needed for a room is:

\[ TL = A \times LSF \]

Where:

\(TL\) is the Total Lumens Needed for the Room
\(A\) is the Room Area (ft²)
\(LSF\) is 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.

Example Calculation 1

Let's assume the following values:

Room Area (\(A\)) = 150 ft²
Lumens per Square Foot (\(LSF\)) = 20

Using the formula:

\[ TL = 150 \times 20 = 3000 \text{ lumens} \]

The Total Lumens Needed is 3000 lumens.

Example Calculation 2

Let's assume the following values:

Room Area (\(A\)) = 200 ft²
Lumens per Square Foot (\(LSF\)) = 15

Using the formula:

\[ TL = 200 \times 15 = 3000 \text{ lumens} \]

The Total Lumens Needed is 3000 lumens.
