Variables

Candle Power

Candle power is an older term used to describe the intensity of light emitted by a source, but it has largely been superseded by the SI unit candela for modern illumination measurements.

Symbol: CP

Measurement: Luminous IntensityUnit: cd

Note: Value should be greater than 0.

Formulas to find Candle Power

Luminous Flux

Luminous flux is a measure of the total amount of light emitted by a light source in all directions. It quantifies the overall brightness or output of the source.

Symbol: F

Measurement: Luminous FluxUnit: lm

Note: Value can be positive or negative.

Formulas to find Luminous Flux

Solid Angle

Solid angle is a measure of the extent of a cone-shaped region in three-dimensional space, originating from a point and defined by its vertex angle. It quantifies the spatial coverage.

Symbol: ω

Measurement: Solid AngleUnit: sr

Note: Value can be positive or negative.

How to Evaluate Candle Power?

Candle Power evaluator uses Candle Power = Luminous Flux/Solid Angle to evaluate 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.
