A tracklight system includes an elongated an elongated metallic track in the shape of an inverted U having a generally horizontal base with parallel, vertical depending sides, each side terminating at a distal end in a common plane with an outward facing support flange for a ceiling panel. The inward-facing side of at least one side supports an elongated 3-conductor electrical receptacle having polarized longitudinal slots holding electrical conductors therein. A number of lamp assemblies are positionable in longitudinal slots each with flexible wires terminating in a plug matching the polarized electrical receptacle. A thermal barrier in the ceiling plane prevents lamp heat from radiating in the downward direction into a room.
