Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

20 ILCS 3953/25

    (20 ILCS 3953/25)
    Sec. 25. Fluorescent or LED lighting in State buildings. In order to reduce energy consumption, all buildings owned or leased by the State that are 1,000 square feet in size or larger shall, where practicable, use:
        (1) Energy Star labeled light bulbs as defined by the
Energy Star Program of the United States Environmental Protection Agency;
        (2) Light-emitting diode (LED) luminaires, lamps,
and systems whose efficacy (lumens per watt) and Color Rendering Index (CRI) meet the Department of Energy requirements for minimum luminaire efficacy and CRI for the Energy Star certification, as verified by an independent third-party testing laboratory that the federal Environmental Protection Agency Administrator and the Secretary of Energy determine conducts its tests according to the procedures and recommendations of the Illuminating Engineering Society of North America, even if the luminaires, lamps, and systems have not received such certification; or
        (3) Any combination of (1) and (2).
    Prior to implementing the use of Energy Star Light Bulbs, any building to which this Section applies may deplete the supply of non-Energy Star Light Bulbs it possesses on the effective date of this amendatory Act of the 95th General Assembly. Additionally, as most light bulbs contain mercury, all buildings to which this Section applies shall ensure the proper disposal of used light bulbs at a certified hazardous waste recycling facility.
    Historic buildings that are listed on the Illinois Register of Historic Places, established pursuant to Section 6 of the Illinois Historic Preservation Act, are exempt from the requirements of this Section.
