LED lamp includes a housing, a mounting base, a light engine (LE) , light-transmissive cover circumscribing the LE, and reflector . The LE comprises a plurality of top-emitting LED packages (TE-LED packages) mounted on planar upper surface of PC board , each configured to emit light having an angular distribution centered around a principal light-emitting direction (PLED) normal to an emission face . A first set of TE-LEDs is mounted with its PLED perpendicular to PCB and a second set of TE-LEDs is mounted to the PCB with its PLED orthogonal to that of the first set of TE-LEDs and parallel to upper surface . Reflector disposed below LE reflects light towards cover . A polar light distribution of light emitted from LED lamp is omnidirectional and is Energy Star compliant. 110.
