In lighting, led troffer light is a recessed lighting fixture typically installed in a grid ceiling system, such as a suspended ceiling. The word “troffer” comes from the combination of “trough” and “offer,” indicating that the fixture is designed to be installed in a slot-like opening in the ceiling.Main features of recessed lighting:

1. Design: Troffer lights are typically rectangular or square and designed to sit flush with the ceiling. They often have lenses or reflectors that help distribute light evenly throughout the space.

2. SIZES: The most common sizes for led troffer lights are 2×4 feet, 2×2 feet, and 1×4 feet, but other sizes are available.

3. Light Source: Troffer light troughs can accommodate a variety of light sources, including fluorescent tubes, LED modules, and other lighting technologies. LED troffer light troughs are increasingly popular due to their energy efficiency and long lifespan.

4. Installation: troffer luminaires are primarily designed to be embedded in the ceiling grid and are a common choice in commercial spaces such as offices, schools, and hospitals. They can also be surface-mounted or suspended, but this is less common.

5. Application: LED troffer light fixture troughs are widely used for general ambient lighting in commercial and institutional locations. They provide effective lighting for workplaces, corridors, and other areas requiring stable lighting.

Overall, led troffer lighting is a versatile and practical lighting solution, especially in environments where a clean, integrated look is desired.
