Abstract: A T-LED light engine that provides up-light and down light. The T-LED has a top lens that emits a “bat-wing” light pattern and a bottom lens that emits a Lambertion light pattern. The T-LED light engine has an internal or on-board driver unit and/or on-board control unit. End caps of the T-LED light engine can be removed to service or replace internal components. The end caps have two-pin contact configurations that mate with tombstone style sockets or connectors and/or have bridge connector for connecting multiple T-LED light engines in series.
