Western Force eventually found its try-scoring touch to inflict a 12th successive Super 14 12-33 defeat on the Lions.
After David Hill and Herkie Kruger traded four first-half penalties apiece, Scott Staniforth broke through late in the first half.
And scores after the break from Hill and Mark Bartholomeusz made victory secure, leaving the Force 11th in the table.
Hill set the Perth side on its way with two penalties in the first three minutes.
And it led 9-3 after the Lions' Kruger and Hill traded further shots, with Brett Sheehan off target for the Force with another effort in between.
Hill stretched the lead by a further three points as the kicking duel continued, but indiscipline from the Australian side allowed Kruger to kick nine points in eight minutes and level the scores at 12 apiece.
Flanker Matt Hodgson had been sin-binned along the way, but when the Lions' Wikus van Heerden followed five minutes before the interval the Force took full advantage.
A rare passage of spirited attacking running saw Bartholomeusz make good ground and set up a move which ended with Staniforth touching down. Hill added the extras to make it 19-12 at the interval.
Whatever Dick Muir and Ray Mordt said to the Lions at half-time seemed to spur them into life and they twice surged towards the visitors' line only to knock on as the chance presented itself.
The Force responded and Nathan Sharpe was held at bay a yard out before good work by prop Matt Dunning went to waste as a subsequent pass went to ground.
Staniforth was forced into touch but the breakthrough came when Pek Cowan received good line-out ball and put Hill over, the first five-eighths converting his own try.
And Hill repeated the dose after Bartholomeusz crossed to complete a comfortable win.
