Wellingborough's hopes of reaching the East Midlands Cup Final ended at the last four stage as they were beaten by Luton, who play two leagues higher.
The home side put up a battling performance and stayed in contention until the final quarter but the visitors had too much left in the tank.
The contest started well for Wellingborough with Andy Seaton
touching down after five minutes, Tom Mair
converting to put them 7-0 ahead. With the host's backs running well, winger Luke Gardiner
waltzed around the Luton defence to score under the posts with Mair's conversion making it 14-0 after twenty minutes.
Luton then hit back to score three tries, one of which was converted and a penalty kick to make the score 20-17 in Luton's favour at the halfway point.
In the second period, Wellingborough kept their visitors at bay for the first twenty minutes of the half. But with Luton's trasgressions going unpunished by a lenient match official, they were forced to use all their replacements.
This disrupted the cohesion of the team and allowed Luton again to score three more tries and book their spot in the final.
