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 4100K lamps 5 ECT-232-M-EB8/PLUS 2 3100 94% 88% 1.15 5898 1.95 1.68 8236 73
