Total Luminous Flux Calculator

This online calculator is used to calculate the total luminous flux (in lumens) emitted by a light source. Determining the total amount of light emitted from a source is important in the design and performance evaluation of lighting systems. This Total Luminous Flux Calculator allows users to quickly and accurately calculate the total luminous flux by entering the power and luminous efficiency of the light source.

When using the online Total Luminous Flux Calculator: you can calculate by entering Maximum Luminous Intensity and Cone Full Angle.

How is Total Luminous Flux Calculated Using Our Calculator?

Total luminous flux measures the total amount of light emitted by a light source and is expressed in lumens (lm). You can follow the steps below to calculate the total luminous flux using our Total Luminous Flux Calculator:

1. Determine the Power of the Light Source: Input the rated power (watts) of the light source.
2. Determine the Luminous Efficiency: Input the luminous efficiency of the light source (lm/W).
3. Calculate Total Luminous Flux: The calculator will automatically multiply the power by the luminous efficiency.

Expressed as a formula:

For example, if the luminous efficiency of a 10 watt LED bulb is 100 lm/W, the total luminous flux can be calculated as follows:

This way you can calculate the total amount of light emitted by the light source in lumens using our Total Luminous Flux Calculator.

What is Total Luminous Flux?

Total Luminous Flux is a term that measures the total amount of light emitted by a light source. It refers to the total power of light emitted from the light source and is measured in lumens (lm). Total luminous flux determines the lighting capacity of a light source and indicates how bright the light source is.

Total luminous flux is directly related to the power and efficiency of the light source. A light source with high power and high efficiency will have a higher total luminous flux, resulting in brighter lighting. Total luminous flux is an important parameter in lighting design and determining lighting requirements. For more related calculator click here.
