The formula to calculate Lumens (\(lm\)) from Lux (\(lx\)) is:
\[ lm = lx \times A \]
Where:
Lux (lx) is a measure of illuminance, the total amount of visible light illuminating a point on a surface. Lumens (lm) measure the total amount of visible light emitted by a source.
The area is the surface over which the light is spread, measured in square meters.
Let's assume the following values:
Using the formula:
\[ lm = 500 \times 10 \]
Evaluating:
\[ lm = 5000 \]
The Lumens is 5000 lm.
