The formula to calculate lumens (\(L\)) is:
\[ L = \frac{E_{av} \times L_{room} \times W_{room}}{0.32} \]
Where:
Average illuminance is the total luminous flux incident on a surface, per unit area. It is measured in lux (lx).
Lumens measure the total amount of visible light emitted by a source. It is measured in lumens (lm).
Let's assume the following values:
Using the formula for lumens:
\[ L = \frac{300 \times 5 \times 4}{0.32} \approx 18750 \, \text{lm} \]
The lumens are approximately 18750 lm.
