What is the realtion between candle power and lumens?
Candlepower, also known as candelas (cd), is a measure of luminous intensity. It quantifies the amount of light emitted by a light source in a specific direction. On the other hand, lumens (lm) measure the total amount of light emitted by a light source in all directions, regardless of the directionality.
To relate candlepower to lumens, you need to consider the beam angle or the angular distribution of the light emitted by the source. The total luminous flux in lumens can be calculated by multiplying the luminous intensity in candelas by the solid angle in steradians (sr) that the light is emitted within.
How to Calculate Candle Power?
Candle Power calculator uses Candle Power = Luminous Flux/Solid Angle to calculate the Candle Power, The Candle Power formula refers to a unit of measurement used to quantify the intensity of light emitted by a light source in a specific direction. Candlepower is an older term that has been largely replaced by the more standardized unit of measurement known as the candela (cd). The candela is defined as the luminous intensity in a given direction of a light source that emits monochromatic radiation at a frequency of 540 terahertz (THz) and has a radiant intensity of 1/683 watt per steradian. Candle Power is denoted by CP symbol.
