The Lumens Candlepower Calculator is an essential online tool that facilitates the conversion between two fundamental units of light measurement: lumens and candlepower. Lumens measure the total amount of visible light emitted by a source, useful in quantifying the brightness that a light fixture disperses throughout a space. Conversely, candlepower quantifies the intensity of light at the source, focusing on the strength of light emitted in a particular direction.
Purpose and Importance
This calculator helps users:
- Understand the intensity of light sources in lumens when only candlepower ratings are available.
- Compare light sources by converting candlepower (intensity) to lumens (brightness).
- Make informed decisions in purchasing and installing lighting solutions, ensuring the appropriate intensity and brightness for their needs.
Formula of Lumens Candlepower Calculator
The conversion formulas between candlepower and lumens are straightforward yet pivotal for precise calculations:
Converting Candlepower to Lumens
Formula: Lumens=Candlepower×12.57
This formula implies that one candlepower is equivalent to 12.57 lumens.
Converting Lumens to Candlepower
Formula: Candlepower=Lumens / 12.57
These formulas are essential for professionals in fields where light measurements are critical, such as photography, cinematography, and interior design.
Conversion Table
| Candlepower (cp) | Lumens (lm) |

This table serves as a quick reference for converting common candlepower values to lumens without manual calculations.
Example of Lumens Candlepower Calculator
Scenario
A projector emits a light with an intensity of 50 candlepower. What is the luminosity of this light in lumens?
Calculation:
Using the formula: Lumens=50 cp×12.57=628.5 lm
Interpretation
The projector’s light has a luminosity of 628.5 lumens, providing ample brightness for presentations in medium-sized rooms.
Most Common FAQs
Lumens measure the total visible light emitted by a source in all directions, whereas candlepower measures the intensity of light in a specific direction. Lumens provide a comprehensive view of a light’s output, while candlepower focuses on its intensity.
Enter the value you know (either in lumens or candlepower) into the calculator, select the appropriate unit, and the tool will convert it to the other unit instantly.
No, the Lumens Candlepower Calculator specifically converts between lumens and candlepower. Converting lumens to watts, which measures power consumption rather than light output, requires a different calculation depending on the efficiency of the light source.
