1 AN ACT concerning safety.
2 Be it enacted by the People of the State of Illinois,
3 represented in the General Assembly:
4 Section 1. Short title. This Act may be cited as the
5 Responsible Outdoor Lighting Control Act.
6 Section 5. Findings. The General Assembly finds that:
7 (1) Article XI of the Illinois Constitution states the
8 public policy of the State and the duty of each person is
9 to provide and maintain a healthful environment for the
10 benefit of this and future generations and that the
11 General Assembly shall provide by law for the
12 implementation and enforcement of this policy.
13 (2) The House of Representatives has resolved in House
14 Resolution 884 of the 96th General Assembly to (i) express
15 its support for improved night preservation practices in
16 Illinois, (ii) encourage State agencies to adopt suitable
17 outdoor lighting practices based on the principles of
18 applying artificial light only where it is needed, when it
19 is needed, and to only the levels needed using the best
20 safety and energy-efficient standards available, and (iii)
21 encourage the Illinois Sustainable Technology Center of
22 the University of Illinois to provide artificial outdoor
23 illumination engineering assistance to State agencies,

1 municipalities, and businesses that seek to implement
2 responsible outdoor lighting to conserve and preserve the
3 important natural phenomenon of night.
4 (3) The Senate has resolved in Senate Resolution 64 of
5 the 103rd General Assembly that local governments in
6 Illinois should abide by the International Dark-Sky
7 Association (now known as Dark Sky International)
8 guidelines and lighting principles to help mitigate the
9 effects of light pollution produced by outdoor lighting.
10 (4) The State should promote responsible outdoor
11 lighting.
12 (5) Government structures, facilities, places, and
13 spaces should serve as models of best practices for
14 private structures, facilities, places, and spaces. These
15 government structures, facilities, places, and spaces
16 should encourage residents, business owners, and others to
17 join in transitioning to responsible lighting.

16 (1) Permanent outdoor luminaires must be fully
17 shielded with an IES BUG rating and produce less than 1% of
18 its emitted light above 80 degrees from the downward
19 vertical direction of nadir. Light should not be emitted
20 at an angle above 60 degrees from the downward vertical

24 level both horizontally and vertically at the property
25 boundary.

1 (3) Luminaires must have a correlated color
2 temperature less than or equal to 2,700 Kelvin. In
3 residential areas, dark sky locations, or environmentally
4 sensitive areas, such as State parks and outdoor
5 recreation facilities, correlated color temperature should
6 be no more than 2,200 Kelvin.
7 (4) Outdoor lighting must be minimized to no more than
8 25% above ANSI/IES standards or United States Department
9 of Transportation recommendations.
10 (5) Facade lighting must be minimized to no more than
11 25% above ANSI/IES standards, must project downward, and
12 must not violate the light trespass limits in paragraph
13 (2).
14 (6) When the installation or replacement of roadway
15 lighting is planned, the appropriate authority must
16 determine whether reflective roadway markings or
17 reflective signage is appropriate and safe for the
18 situation in lieu of outdoor lighting. Reflectorized
19 roadway markings, lines, warning signs, informational
20 signs or other passive means must be used for roadway
21 lighting, except at intersections of 2 or more streets or
22 highways, unless it is determined that adequate safety
23 cannot be achieved by reflective means.
24 (7) No artificial lighting above one lux, as measured
25 at ground level both horizontally and vertically, may
26 trespass onto land or waterways designated or managed as

2 Section 20. Exceptions. This Act does not apply if:
3 (1) the luminaires are on a structure or land that is

5 in a county or municipality that, by ordinance or
6 resolution, has adopted provisions that are equal to or
7 more stringent than the provisions of this Act;
8 (2) a federal law or regulation preempts this Act;
9 (3) a State agency determines a safety or security
10 need exists that cannot be addressed by any other method;
11 (4) fire, police, rescue, or repair personnel need
12 light for temporary emergencies or road repair work;
13 (5) it has been determined that a reasonable safety
14 and security interest exists at correctional or hospital
15 facilities that cannot be addressed by another method as
16 long as it complies with existing standards,
17 specifications, or policies;
18 (6) navigational lighting systems and other lighting
19 are necessary to comply with Federal Aviation
20 Administration airside operations or nautical safety;
21 (7) lamps greater than 2,700 Kelvin are used on active
22 sports grounds or show grounds, but only for the duration
23 of a practice, match, or event. Lamps emitting greater
24 than 2,700 Kelvin under this paragraph must be positioned,
25 angled, or shielded to prevent direct glare and light

3 emission to only the amount necessary to light the
4 sporting or grounds activity;
5 (8) flagpoles installed after the effective date of
6 this Act are lit by means of a downward-facing lamp and
7 using a lamp of 2,700 Kelvin or lower;
8 (9) flagpoles installed on or before the effective
9 date of this Act are upward-lit by partially shielded or
10 unshielded luminaires using a lamp of 2,200 Kelvin or
11 lower to minimize the impact of glare, light trespass, and
12 sky glow and are converted to conform to requirements upon
13 retrofitting;
14 (10) the luminaries are existing decorative and
15 ornamental lighting that serve historical purposes, but
16 replacement luminaries for the existing decorative and
17 ornamental lighting must meet the standards of this Act;
18 or
