troffer
Grid ceiling lamp
A troffer is a rectangular light fixture designed to fit into a modular dropped ceiling grid, typically holding fluorescent tubes or LED panels.
The name likely blends "trough" and "coffer." Troffers provide even, diffused illumination in offices, schools, hospitals, and commercial spaces: The maintenance crew replaced the old fluorescent troffers with energy-efficient LEDs.
