FOOTNOTES: 1 Lumen maintenance is based on lamp manufacturer's stated data 2 Design System Lumens is the fixture lumens at 40% of rated lamp life and is calculated as Quantity of Lamps x Lamp Lumens x
Lumen Maintenance x Fixture Efficiency x Ballast Factor 3 S/P Ratio is the lamp manufacturers stated Scotopic/Photopic Ratio; accepted by some lighting designers to adjust for the relative strengths of scotopic
and photopic vision, not yet adopted by IESNA 4 S/P Adjusted Lumens calculates the brightness perception scotopic/photopic ratio as Design System Lumens x (S/P)^ 0 5 based on 5000K lamps 5 LER (Luminaire
Efficiency Ratio) is an accepted method of comparing fixture performance
