Making his first start this year, Kahraba found the net with five minutes remaining but his strike was never enough for Luzern.
It was the first time for the 19-year-old to play full 90 minutes since joining from ENPPI last summer.
Kahraba became Luzern's joint-top-scorer in the league with five goals so far this season.
Luzern dropped to fourth place in the league table, seven behind leaders Basel.
