i. Outdoor recreation and/or athletic fields
(1) Outdoor lighting of the outdoor athletic field of an organized event on public property that is in progress at the close of permitted outdoor lighting hours shall be allowed to remain illuminated until thirty (30) minutes after the conclusion of the event but no later than ten o’clock (10:00) p.m. Thereafter, for an additional thirty (30) minutes, lighting is permissible at a total light output not greater than thirty percent (30%) of the total light output from all outdoor lighting of a recreation and/or athletic field for additional tasks other than active play (e.g. field maintenance). No outdoor lighting of the outdoor athletic field for any sport or recreational purpose shall be initiated after ten o’clock (10:00) p.m.
(2) Lighting controls shall be provided to prevent outdoor lighting of a recreation and/or athletic field to accidentally remain on overnight using a control device or system such as an astronomic time switch or equivalent function from a programmable lighting controller, building automation system or lighting energy management system, all with battery or similar backup power or device.
E. Any luminaire's light source which is used for outdoor lighting within a non-residence zoning district or residence zoning district shall have a correlated color temperature (CCT) not to exceed three thousand degrees kelvin (3,000°K).
F. Any luminaire with a light output exceeding one thousand (1,000) initial luminaire lumens which is used for outdoor lighting within a non-residence zoning district or residence zoning district shall have necessary shielding and/or beam-angle control and/or shall be installed in the proper orientation to achieve fully shielded performance with respect to a horizontal plane. Any luminaire less than one thousand (1,000) initial luminaire lumens do not require shielding.
1. If a motion-activated sensor that illuminates the luminaire for no more than five (5) minutes upon activation is used, however, said luminaire shall have a light output of up to two thousand (2,000) initial luminaire lumens.
G. Any luminaire which is used for uplighting within a non-residence zoning district or residence zoning district shall have necessary beam-angle control and/or shall be aimed substantially confine the directed light to the object intending to be illuminated. Uplighting shall only be permitted for landscape lighting, architectural lighting, flag lighting, and lighting of ground-mounted signs (Section 9-12). Uplighting shall meet the following requirements:

H. Except for street lighting, light emitted from outdoor lighting within a non-residence zoning district or residence zoning district shall be mitigated onto adjacent properties via maximum allowable backlight, up light and glare (BUG) ratings defined on a manufacturer's cut sheet:
1. A luminaire may be used if it is rated equivalent or lower in number for all ratings B, U, G.
a. Allowed backlight (B) rating:
(1) For property lines that abut public walkways, bikeways, plazas, and parking lots, the property line may be 5 feet beyond the actual property line for purpose of determining compliance. For property lines that abut public roadways and public transit corridors, the property line may be the centerline of the public roadway or public transit corridor for the purpose of determining compliance.
(2) A luminaire located no greater than two mounting heights from the property line shall not exceed a backlight (B) rating of B4.
(3) A luminaire less than two mounting heights but greater than one mounting height from the property line and oriented so that the backlight portion of the light output is perpendicular to the property line of concern shall not exceed a backlight (B) rating of B3.
(4) A luminaire less than one mounting heights but greater than ½ mounting height from the property line and oriented so that the backlight portion of the light output is perpendicular to the property line of concern shall not exceed a backlight (B) rating of B2.
(5) A luminaire less than ½ a mounting height from the property line and oriented so that the backlight portion of the light output is perpendicular to the property line of concern shall not exceed a backlight (B) rating of B0.
b. Allowed up light (U) rating:
(1) Any luminaire within a non-residence zoning district or residence zoning district shall not exceed an uplight (U) rating of U0 or emit no light above the horizontal plane (90º) unless otherwise stated herein.
c. Allowed glare (G) rating:
(1) A luminaire less than two mounting heights but greater than one mounting height from the property line and oriented so that the backlight portion of the light output is perpendicular to the property line of concern shall not exceed a glare (G) rating of G1.
(2) A luminaire less than one mounting heights but greater than ½ mounting height from the property line and oriented so that the backlight portion of the light output is perpendicular to the property line of concern shall not exceed a glare (B) rating of G0.
(3) A luminaire less than ½ a mounting height from the property line and oriented so that the backlight portion of the light output is perpendicular to the property line of concern shall not exceed a glare (G) rating of G0.
2. Luminaires equipped with adjustable mounting devices permitting alteration of luminaire aiming shall not be permitted.
I. For the purpose of this Chapter 19, the initial luminaire lumens (absolute photometry) of a solid-state luminaire, such as an LED is defined on a manufacturer's cut sheet. Other luminaires tested with relative photometry will have initial luminaire lumens which can be calculated by multiplying initial lamp lumens by the luminaire efficiency.
J. Any luminaire used for street lighting shall be a fully shielded LED light source in correlated color temperature (CCT) not to exceed three thousand degrees kelvin (3,000°K) as measured in degrees Kelvin and shall be installed in the proper orientation to achieve fully shielded performance with respect to a horizontal plane at all public and private streets. Said luminaire, as well as any poles, brackets, supports, and mounting hardware, shall be reviewed by the village.
1. The design for a street lighting system shall be in accordance with the Illuminating Engineering Society's (IES) Lighting Handbook, latest edition, and their publication of recommended practice for street lighting, ANSI/IES RP-8-14 Roadway Lighting, latest edition.
