After a goalless first half, the Hatters found the back of the net twice as Pelly-Ruddock Mpanzu fired in his first goal of the campaign from Andrew Shinnie's cross just after the hour mark, before Elliot Lee bent one into the bottom right corner from 22 yards with ten to play.
Jones said: "I think it was as good [as recent home performances], I just don't think it was as fluent. It was a different type of game, they matched us up man for man all over the pitch, there wasn't space to exploit.
"We showed a thoroughly professional side to us, we kept a clean sheet, we defended our box well against difficult opponents because they're in a false position. They shouldn't be where they are, we've watched them and they have got some decent players, Hanson is a real threat. I think he was marshalled fantastically well by our centre-halves and Glen Rea in front of them.
"So we really had to dig in today and show our character and our performance levels and I am very, very pleased with that. First half we weren't really at it, second half I thought much, much better. The margin should have been far greater."
