A. Energy Efficiency: LED, induction or some other form of energy efficient lighting should be used whenever possible.
B. Walkways: Illuminance levels for parking lots, sidewalks and other walkways affected by side mounted building lights, and freestanding sidewalk lights (not streetlights) shall not exceed illuminance levels listed in the most current IESNA recommended practices. The city of Hailey recognizes that not every such area will require lighting or lighting to the extent recommended by the most current IESNA recommended practices.
C. Parking Lots: Parking lot lighting shall not exceed an overall average illumination of one and five-tenths (1.5) foot-candles.
D. Streetlights: Streetlights shall be high pressure sodium, low pressure sodium or metal halide, or a more energy efficient type. All streetlights within all zoning districts shall be a maximum of one hundred (100) watts hps, or have a maximum lumen output of nine thousand five hundred (9,500), except lights at traffic signal controlled intersections on state highways shall be a maximum of two hundred fifty (250) watts hps, or a maximum lumen output of twenty seven thousand five hundred (27,500). If a light type other than high pressure sodium is used, then the equivalent output shall be the maximum for the other light type (see section 17.08C.040.05, table 1 of this article). LED and induction lights do not have an equivalent lumens output compared to traditional light types found in section 17.08C.040.05, table 1 of this article; therefore, the number of foot-candles shall not exceed those compared to the initial lumens of existing compliant streetlights with the same placement height.
E. Light Trespass: All existing and/or new exterior lighting shall not cause light trespass and shall protect adjacent properties from glare and excessive lighting. (Ord. 1191, 2015)
