Goals from Chris Coyne and Jaroslaw Fojut helped League One side Luton dispose of League Two outfit Brentford in their FA Cup second round replay.
Coyne got on the end of Darren Currie's floated corner after 36 minutes, nodding home to give his side the lead.
Fojut powered into the top corner to double the lead after a long throw.
The Bees dominated possession but lacked a cutting edge with Glenn Poole's long-range strike and Lee Thorpe's header the only real efforts.
