What Is Candela to Lux Conversion?
Candela (cd) measures the intensity of light in a specific direction.
Lux (lx) measures how much light falls on a surface.
To measure how bright a surface appears, you need to convert candela to lux.
How to Convert Candela to Lux
The conversion is simple.
You only need the candela value and distance in meters between the light source and the surface.
Our calculator does this for you in seconds.
Candela to Lux Formula
Here’s the formula:
Lux = Candela / Distance²
So if a light source has 100 cd intensity and is 2 meters away:
Lux = 100 / 2² = 25 lux
This shows the surface gets 25 lux of light.
Is 1 Lux Equal to cd/m²?
No, 1 lux is not equal to cd/m².
They measure different things.
- Lux is for light falling on a surface (illuminance).
- cd/m² is for light emitted or reflected from a surface (luminance).
