A light engine ( 10 ) has a light engine subassembly ( 12 ) comprising: a housing ( 14 ) having a longitudinal axis ( 16 ), a tubular portion ( 18 ) with a surrounding wall ( 20 ) and a closed end ( 22 ). A slot ( 24 ) is formed in the surrounding wall ( 20 ) and terminates at the closed end ( 22 ). A solid-state light source ( 26 ) is mounted adjacent the closed end ( 22 ), the solid-sate light source having energizing wires attached thereto and exiting the housing via the slot ( 24 ). A light dispenser ( 36 ) having a first end ( 37 ) is fixed in the tubular portion ( 18 ) and extends for a given distance along the longitudinal axis ( 16 ). The light engine can be used for backlighting.
