Variables

Maintenance Factor

Maintenance factor refers to a multiplier or percentage used to adjust the initial illumination levels of a lighting system to account for degradation and dirt accumulation over time.

Symbol: MF

Measurement: NAUnit: Unitless

Note: Value can be positive or negative.

Formulas to find Maintenance Factor

Final Illumination

Final illumination refers to the level of light or brightness achieved in a particular space or area after all lighting fixtures and sources have been installed and turned on.

Symbol: I_final

Measurement: IlluminanceUnit: lx

Note: Value can be positive or negative.

Formulas to find Final Illumination

Initial Illumination

Initial illumination refers to the starting level of light in a given area when the lighting fixtures are initially turned on before any adjustments or changes are made.

Symbol: I_initial

Measurement: IlluminanceUnit: lx

Note: Value can be positive or negative.

Go Mean Spherical Candle Power

M.S.C.P. = \frac{F}{4 \cdot π}

How to Evaluate Maintenance Factor?

Maintenance Factor evaluator uses Maintenance Factor = Final Illumination/Initial Illumination to evaluate the Maintenance Factor, The Maintenance Factor formula is defined as the ratio between the illumination under normal working conditions to the illumination when everything is clean. Maintenance Factor is denoted by MF symbol.

How to evaluate Maintenance Factor using this online evaluator? To use this online evaluator for Maintenance Factor, enter Final Illumination (I_final) & Initial Illumination (I_initial) and hit the calculate button.

FAQs on Maintenance Factor
