What is Full-Cutoff Fixture

A full-cutoff fixture is an outdoor lighting fixture designed to minimize light pollution and direct the light output in a controlled manner. It is constructed with a shield or hood that prevents light from being emitted above a certain angle, ensuring that the light is focused downward onto the intended target area. This design feature helps to reduce light spillage and prevents unnecessary light from being emitted into the sky or surrounding areas.

The full-cutoff fixture improves lighting efficiency and reduces the negative impacts of light pollution. By directing the light downward, these fixtures minimize glare, enhance visibility, and improve safety in outdoor spaces such as parking lots, walkways, and business entrances. Additionally, full-cutoff fixtures are often used in areas with dark-sky compliance rules and regulations, which aim to preserve the natural darkness of the night sky and minimize light pollution.

Full-cutoff fixtures are recognized as superior in terms of their ability to address light pollution and trespass. They are commonly used in modern installations on state and federal highways, where their design helps to minimize the wasteful scattering of light and ensure that the lighting is efficient, focused, and environmentally friendly.
