Section 6.2.B. Frontage Row of Vehicle Display Areas. Lumen Limit. Figure: 60 lumens per square foot Type: technical The limit of 60 lm per square foot is based on efficient lighting design using metal halide fixtures, and allows 150% of the highest illumination level listed in the IESNA recommended practice RP-33-99 Lighting for Exterior Environments (IESNA, 1999). Lighting using white LEDs should be able to achieve approximately 200% of the RP-33-99 recommendation. Section 6.3.B. Service Station Canopies. Total Under-Canopy Output. Figure: 60 lumens per square foot Type: technical The limit of 60 lm per square foot is based on efficient lighting design using metal halide fixtures, and allows 150% of the highest illumination level listed in the IESNA recommended practice RP-33-99 Lighting for Exterior Environments (IESNA, 1999). Lighting using white LEDs should be able to achieve approximately 200% of the RP-33-99 recommendation.
