## < 7 Methods of Lighting Calculators

Number of Lamps Required for Illumination
Number of Lamp = (Illumination Intensity*Area of Illumination)/(Luminous Flux*Utilization Factor*Maintenance Factor)
Intensity of Light Transmitted
Intensity of Transmitted Light = Intensity of Light Entering the Material*exp(-Absorption Coefficient*Path Length)
Number of Floodlighting Units
Number of Floodlighting Units = (Area to be Lighted*Illumination Intensity)/(0.7*Lumen Flux)
Spectral Transmission Factor
Spectral Transmission Factor = Transmitted Spectral Emission/Spectral Irradiation
Spectral Reflection Factor
Spectral Reflection Factor = Reflected Spectral Emission/Spectral Irradiation
Spectral Luminous Efficacy
Spectral Luminous Efficacy = Maximum Sensitivity*Photopic Efficiency Value
Luminance for Lambertian Surfaces
Luminance = Illumination Intensity/pi

## Spectral Reflection Factor Formula

Spectral Reflection Factor = Reflected Spectral Emission/Spectral Irradiation

## What is luminous reflectance factor?

The LRF is defined as the colour contrast between two material surfaces, and is calculated by mathematical formula that uses the LRV's of each material. As a general rule, the LRF will not be meaningful insofar as a Dryvit application is concerned.
