troffer

A troffer is a type of light fixture commonly found in commercial and institutional buildings. It is characterized by its recessed design, meaning it is installed into a suspended ceiling grid. The term "troffer" is derived from "trough," referring to the shape of the fixture's housing. Troffers typically hold fluorescent lamps or LED arrays and are designed to provide general illumination over a wide area.

These fixtures are valued for their efficiency in lighting large spaces and their ability to blend seamlessly with ceiling architecture. They are often used in offices, schools, hospitals, and retail environments where consistent and uniform lighting is required. The typical troffer shape is rectangular, designed to fit standard ceiling tile sizes. Many troffers feature diffusers or lenses to soften the light and reduce glare.

Modern troffers have largely transitioned from fluorescent tubes to more energy-efficient LED technology. LED troffers offer benefits such as longer lifespan, lower energy consumption, and greater design flexibility. They can also be equipped with smart lighting controls, allowing for dimming and occupancy sensing to further optimize energy usage. The installation of troffers involves placing them within the ceiling grid, often replacing a standard ceiling tile.
