The ban is part of a larger effort to reduce energy consumption and greenhouse gas emissions. Incandescent bulbs are notoriously inefficient, converting only about 10% of the energy they consume into visible light, with the rest lost as heat. This inefficiency means that they require more energy to produce the same amount of light as more efficient alternatives like LED or CFL bulbs.

The Act aims to reduce energy consumption and carbon emissions by phasing out inefficient lighting. The legislation mandates the transition to LED lighting, which is more energy-efficient and has a longer lifespan. The Act also includes provisions for financial incentives and support for businesses and households to make the switch. The transition to LED lighting is expected to save consumers money on their electricity bills and contribute to a significant reduction in greenhouse gas emissions. The Clean Lighting Act is a key component of Illinois’ broader strategy to combat climate change and promote sustainable energy use. The Clean Lighting Act, enacted in Illinois in 2026, represents a significant step towards reducing energy consumption and carbon emissions.

Consider this your friendly Illinois warning that your fluorescent bulbs are about to go the way of the hula-hoop. Happy lighting.
