- Fill in the values you know. Fields already contain typical example values that you can overwrite.
- Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
- Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
- A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.
If a value is missing or does not make sense, the field shows a short message explaining what to fix.
Formulas used
This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:
lumens = candela × 2×pi×(1-cos(theta/2))
lux = candela / distance^2
lux = lumens / area

Frequently asked questions
What is the difference between lumen, lux, and candela?
Lumen (lm) measures the total light output of a light source, while lux (lx) measures illuminance, or how much light is received on a surface per unit area. Candela (cd) measures luminous intensity in a specific direction. Together, these units help in understanding light and its application in various environments.
How do I convert lumen to lux?
To convert lumen to lux, you can use the formula: Lux = Lumens / Area (in square meters). For example, if you have 1000 lumens emitted over an area of 10 square meters, the illuminance in lux would be 100 lux.
Can I convert lux to candela?
Yes, you can convert lux to candela using the formula: Candela = Lux × Area (in square meters). This conversion is useful when you need to determine the intensity of the light in a specific direction.
Is there a simple online tool to perform these conversions?
Yes, there are numerous **lumen calculator** tools available online. They allow you to quickly convert between lumen, lux, and candela without complex calculations. These tools can enhance your understanding of lighting requirements in different settings.
Why is it important to understand these measurements?
Understanding lumen, lux, and candela is crucial for achieving the right lighting levels for different applications, whether for home use, photography, or workplace illumination. It ensures optimal visibility, energy efficiency, and atmosphere.
Where can I learn more about lighting and its measurements?
For a deeper understanding of lighting measurements, you can refer to authoritative sources such as the Illuminating Engineering Society (IES) and the National Institute of Standards and Technology (NIST). These organizations provide valuable insights into lighting science and standards.
