A retrofitting kit includes at least one of an adapter bracket and a retainer configured to engage at least one of an existing troffer light fixture and a T-bar of a ceiling system and a door assembly configured to be held in the ceiling system by the at least one of the adapter bracket and the retainer. The door assembly has a housing, the housing including one or more sidewalls, where the one or more sidewalls extend upward to define a cavity, and a plurality of LEDs having primary light axes extending inward into the cavity. The plurality of LEDs are coupled to the one or more sidewalls and positioned to illuminate at least a portion of the housing from behind with a uniform distribution of light when engaged.
