Lumen Output Calculator

Formula

The formula to calculate the lumen output (LO) is:

\[ LO = E \times P \]

Where:

\( LO \) is the lumen output (lumens)
\( E \) is the efficacy of the light source (lumens per watt)
\( P \) is the power consumption of the light source (watts)

What is Lumen Output?

Lumen output is a measure of the total amount of visible light emitted by a source. The higher the lumen output, the brighter the light. This measure is important for determining the suitability of a light source for a given application, such as indoor lighting, outdoor lighting, or specialized environments.

Example Calculation

Let's assume the following values:

Efficacy of the Light Source (E) = 100 lumens per watt
Power Consumption of the Light Source (P) = 10 watts

Using the formula to calculate the lumen output:

\[ LO = 100 \times 10 = 1000 \]

The Lumen Output (LO) is 1000 lumens.
