24    shielded and:
25            (A) have an IES rating of B0 and G0 on the BUG



SB2763- 6 -LRB103 36055 LNS 66142 b

1        rating system and emit no light above an angle of 60
2        degrees from the downward vertical direction; and
3            (B) have an IES rating of U0 on the BUG rating
4        system and emit zero lumens upward.
5        (2) Outdoor lighting units must be placed to avoid

17    should not exceed more than 2,200 K. No lighting units
18    shall have a correlated color temperature that exceeds
19    2,700 K.
20        (5) The use of outdoor lighting must be minimized to
21    only that which is needed for comfort and safety while
22    still maintaining compliance with responsible lighting
23    principles. Low-intensity facade lighting is permitted as
24    long as the light projects downward and no lighting spills
25    beyond the facade being lit. Between 11 p.m. and 6 a.m.,
26    lighting units must be turned off or dimmed.



SB2763- 7 -LRB103 36055 LNS 66142 b

1        (6) The lighting units in locations that are not in
2    use after 11 p.m., including in environmentally sensitive
3    areas, such as State parks, must use timers that are set to
4    turn off after 11 p.m. or must use motion sensors.
5        (7) Light trespass from the interior of a building or
6    structure must be minimized by lowering window shades
7    after sunset or by turning off lighting when not in use.
8        (8) At the time of installation or replacement, the
9    appropriate authority must determine whether reflective
10    roadway markings or reflective signage is appropriate and
11    safe for the situation in lieu of outdoor lighting.
12    Reflective roadway markings, lines, warning signs,
13    informational signs, or other passive means must be used
14    for roadway lighting, except at intersections of 2 or more
15    streets or highways, unless it is determined that adequate
16    lighting cannot be achieved by reflective means.
17    (b) A lighting unit with a lamp that has a correlated color
18temperature that is greater than 2,700 K, that is installed
19prior to the effective date of this Act, and that produces
20light pollution does not need not be replaced until the end of
21the life of the lamp but must comply with subsection (c).
22    At the end of the life of an existing lamp, partially
23shielded lighting units must be fitted with a new lamp that
24complies with paragraph (4) of subsection (a) and must be
25remediated, either by repositioning or by full shielding, so
26that the lighting unit complies with paragraphs (1) through



SB2763- 8 -LRB103 36055 LNS 66142 b

1(3) of subsection (a).
2    If a State-funded entity possesses unshielded or partially
3shielded lighting units on the effective date of this Act, the
4unshielded or partially shielded lighting units shall be:
5        (1) immediately remediated upon the end of the life of
6    the lamp with a new lamp that complies with paragraph (4)
7    of subsection (a); and
8        (2) remediated either by repositioning the lighting
9    unit or by fully shielding the lamp so that it complies
10    with paragraphs (1) through (3) of subsection (a).
11    If the State-funded entity chooses to replace current,
12unshielded or partially shielded lighting units before the end
13of the life of the lamp, the entity may not purchase new,
14unshielded or partially shielded lighting units as
15replacements. If the entity does purchase new, unshielded or
16partially shielded lighting units as replacements, the entity
17may not receive State assistance for the cost of the new
18lighting units.
19    (c) Wherever possible, existing partially shielded and
20unshielded lighting units shall be repositioned to minimize
21upward-directed light, glare, and light trespass.
22    (d) The requirements of subsection (a) shall apply to all
23lighting units on or in all newly constructed, renovated, and
24retrofitted State-owned, State-supported, State-funded, or
25State-related rights-of-way, roadways and sidewalks, spaces,
26facilities, properties, nonhabitable structures, monuments,



SB2763- 9 -LRB103 36055 LNS 66142 b

1and flagpoles.
2    (e) The requirements of subsection (a) do not apply:
3        (1) If federal laws, rules, or regulations preempt
4    State laws, rules, or regulations.
5        (2) If fire, police, rescue, or repair personnel need
6    light for temporary emergencies or road repair work.
7        (3) If it has been determined that a reasonable safety
8    and security interest exists at correctional and hospital
9    facilities that cannot be addressed by another method
10    without increasing the cost or reducing the effectiveness
11    of the lighting as long as it complies with existing
12    standard specifications or policies.
13        (4) To navigational and other lighting systems
14    necessary for aviation and nautical safety.
15        (5) To municipalities that already comply with this
16    Section.
17        (6) To lighting units on active sports or show grounds
18    may use lamps greater than 2,700 K, but only for the
19    duration of a specific practice, match, or event. Lighting
20    units shall be positioned, angled, or shielded to prevent
21    direct glare and light trespass onto neighboring property
22    or properties. The shielding shall limit upward light
23    emission to only the amount necessary to light the
24    sporting or grounds activity.
25        (7) To new flagpoles that are lit by means of a
26    downward-facing lamp and shall use a lamp of 2,200 K or



SB2763- 10 -LRB103 36055 LNS 66142 b

1    lower. Existing flagpoles that are upward-lighted by
2    partially shielded or unshielded lighting units shall use
3    a lamp of 2,200 K or lower to minimize the impact of glare,
4    light trespass, and sky glow. When appropriate, existing
5    flagpoles shall be converted to new flagpole requirements.
6        (8) To existing ornamental lighting that serves
7    historical purposes and seasonal holiday lighting that is
8    temporary to the season. New ornamental lighting shall
9    strive to comply with the restrictions of this Section
10    regarding shielding and must comply with the requirements
11    of this Section regarding lamps. To the extent that it is
12    available and feasible, ornamental lighting that serves a
13    seasonal holiday purpose should be use lamps of 2,700 K or
14    lower.
15    Section 25. Resources. The Department of Central
16Management Services shall make available a resource guide for
17the public to add compliant lighting to homes and businesses.
18The guide shall include references to publicly accessible
19Internet websites of advocacy groups approved by the State
20that provide education, guidance, and specifications relating
21to the implementation of responsible lighting principles.
