Abstract
A ceiling structure for retaining air filter panels having a grid of interconnected rails. Each rail has a recessed channel for containing a light fixture so that the light fixture does not hang below the ceiling surface. The structure may also include hanger hooks attachable to the rails for suspending fixtures, wall panels, and pivoting wall headers to permit angled arrangements of wall panels. The light fixture attached within the channel is an extruded panel that snaps into the channel and which includes standard light tube connectors.
