Maintenance Factor Solution

STEP 0: Pre-Calculation Summary
Formula Used
Maintenance Factor = Final Illumination/Initial Illumination
MF = Ifinal/Iinitial
This formula uses 3 Variables
Variables Used
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.
Final Illumination - (Measured in Lux) - 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.
Initial Illumination - (Measured in Lux) - 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.
STEP 1: Convert Input(s) to Base Unit
Final Illumination: 6.2 Lux --> 6.2 Lux No Conversion Required
Initial Illumination: 3.1 Lux --> 3.1 Lux No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
MF = Ifinal/Iinitial --> 6.2/3.1
Evaluating ... ...
MF = 2
STEP 3: Convert Result to Output's Unit
2 --> No Conversion Required
FINAL ANSWER
2 <-- Maintenance Factor

15 Illumination Parameters Calculators

Number of Lamps Required for Illumination
Go Number of Lamp = (Illumination Intensity*Area of Illumination)/(Luminous Flux*Utilization Factor*Maintenance Factor)
Index of Refraction
Go Refractive Index of Medium 1 = (Refractive Index of Medium 2*sin(Refracted Angle))/sin(Incident Angle)
Luminance
Go Luminance = Luminous Intensity/(Area of Illumination*cos(Illumination Angle))
Luminous Flux
Go Luminous Flux = (Area of Illumination*Luminous Intensity)/(Length of Illumination^2)
Reduction Factor
Go Reduction Factor = Mean Spherical Candle Power/Mean Horizontal Candle Power
Mean Horizontal Candle Power
Go Mean Horizontal Candle Power = Sum of Candle Power/Number of Lamp
Solid Angle
Go Solid Angle = Area of Illumination/(Radius of Illumination^2)
Maintenance Factor
Go Maintenance Factor = Final Illumination/Initial Illumination
Illumination
Go Illumination Intensity = Luminous Flux/Area of Illumination
Mean Hemi-Spherical Candle Power
Go Mean Hemi Spherical Candle Power = Luminous Flux/(2*pi)
Mean Spherical Candle Power
Go Mean Spherical Candle Power = Luminous Flux/(4*pi)
Lamp Efficiency
Go Lamp Efficiency = Luminous Flux/Input Power
Candle Power
Go Candle Power = Luminous Flux/Solid Angle
Lumens
Go Lumen = Candle Power*Solid Angle
Depreciation Factor
Go Depreciation Factor = 1/Maintenance Factor

Maintenance Factor Formula

Maintenance Factor = Final Illumination/Initial Illumination
MF = Ifinal/Iinitial

Why is Maintenance Factor used?

Maintenance Factor is used to determine depreciation of a lamp or a reflective surface over a period of a time.

How to Calculate Maintenance Factor?

Maintenance Factor calculator uses Maintenance Factor = Final Illumination/Initial Illumination to calculate 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 calculate Maintenance Factor using this online calculator? To use this online calculator for Maintenance Factor, enter Final Illumination (Ifinal) & Initial Illumination (Iinitial) and hit the calculate button. Here is how the Maintenance Factor calculation can be explained with given input values -> 1.935484 = 6.2/3.1.
