A troffer door assembly has a frame assembly, a lens member and a light emitting diode (LED) assembly. The rigid brace member is affixed to the frame assembly such that the rigidity of the frame assembly is increased. Hinge members and latch members are positioned in exterior slots on the frame assembly such that the location of the hinge members and latch members can be adjusted. In this manner installed troffer light fixtures can be retrofitted by replacing the installed troffer door with the troffer door assembly as described.
