Watts to Candlepower Formula
The formula used to calculate candlepower (C) from watts (W) is:
\[ C = \frac{W \times PF}{12.57} \]
Where:
- \( C \) is the candlepower (candela)
- \( W \) is the wattage (watts)
- \( PF \) is the performance factor of the bulb (lumens per watt)
How to Calculate Candlepower from Watts?
To calculate candlepower, follow these steps:
- Multiply the total wattage by the performance factor (lumens per watt).
- Divide the result by 12.57 to obtain the candlepower in candelas.
What is Candlepower?
Definition:
Candlepower, also known as luminous intensity, is a measure of light intensity in a specific direction, typically measured in candelas (cd). It represents how much light is emitted in a particular direction and is often used in the context of lighting performance.
