Candela to Lumen Calculator

Convert candela (cd) to lumen (lm) for your lighting needs. This tool helps you calculate the total luminous flux of a light source, which is crucial in determining how bright a light will be in a given area.

How to Use

To use this calculator, input the candela (cd) of the light source and the solid angle in steradians (sr) over which the light is distributed. The calculator will then convert the candela value to lumens, which is a measure of total light output.

The luminous flux is: lumens.

FAQ

Q: What is Candela?

A: Candela is the unit of luminous intensity, measuring the power emitted by a light source in a particular direction.

Q: What is Lumen?

A: Lumen is the unit of luminous flux, measuring the total quantity of visible light emitted by a light source.

Q: Why is Solid Angle Important?

A: The solid angle represents the spread of the light emitted by the source. It helps in calculating the total light output based on the distribution of light.

الصيغة

The formula for converting candela to lumen is:

Lumens = Candela × Solid Angle (sr)

Why You Need This Tool

This tool allows you to easily convert candela to lumen, which is helpful when selecting light sources based on total light output. Knowing the total lumens helps in understanding how bright a light source will be in your space and ensures proper illumination.
