Formulas to find Reduction Factor

Mean Spherical Candle Power

Mean Spherical Candle Power is a measure that represents the average intensity of light emitted by a source in all directions within a sphere. It quantifies the overall light output.

Symbol: M.S.C.P.

Measurement: Luminous IntensityUnit: cd

Note: Value can be positive or negative.

Formulas to find Mean Spherical Candle Power

Mean Horizontal Candle Power

Mean Horizontal Candle Power is a measure that represents the average intensity of light emitted by a source along the horizontal plane.

Symbol: M.H.C.P.

Measurement: Luminous IntensityUnit: cd

Note: Value can be positive or negative.

Formulas to find Mean Horizontal Candle Power

Go Solid Angle

ω = \frac{A}{r^{2}}

Go Number of Lamps Required for Illumination

N Lamp = \frac{E v \cdot A}{F \cdot UF \cdot MF}

Go Mean Spherical Candle Power

M.S.C.P. = \frac{F}{4 \cdot π}

Go Mean Horizontal Candle Power

M.H.C.P. = \frac{S}{N Lamp}

How to Evaluate Reduction Factor?

Reduction Factor evaluator uses Reduction Factor = Mean Spherical Candle Power/Mean Horizontal Candle Power to evaluate the Reduction Factor, The reduction Factor of the source of light is defined as the ratio of its mean spherical candle power to its mean horizontal candle power. Reduction Factor is denoted by RF symbol.

How to evaluate Reduction Factor using this online evaluator? To use this online evaluator for Reduction Factor, enter Mean Spherical Candle Power (M.S.C.P.) & Mean Horizontal Candle Power (M.H.C.P.) and hit the calculate button.

FAQs on Reduction Factor
