Jon Shaw's first goal since the opening day of the season gave Luton a 2-1 win at Lincoln.
The visitors came into the game on the back of successive league victories, and took the lead after 28 minutes, when Imps' goalkeeper Paul Farman palmed Andre Gray's drilled cross into his own net.
Paul Buckle's side were dominant for most of the first half, but needed goalkeeper Mark Tyler to be alert to keep out Jamie Taylor's low effort four minutes before the break.
Buckle made a double change at half-time which paid immediate dividends as substitute Shaw headed home Stuart Fleetwood's 48th-minute free-kick having been left completely unmarked.
The deficit was reduced 10 minutes later however, when Taylor hammered home a right-footed strike from the edge of the area.
The Hatters sat back on their lead but only David Morgan's long-range effort gave David Holdsworth's men the glimpse of a late equaliser.
