Town boss Nathan Jones said it was a "good feeling" being top of the league over Christmas, as the Hatters ran out 2-0 winners against Grimsby Town at Kenilworth Road this afternoon.
With the game marking the halfway stage in Sky Bet League Two for this campaign, a stunning, curling effort from Luke Berry gave the Hatters the lead five minutes before the break, with James Collins heading in from close range on the hour mark to seal the three points.
It puts the Town four points clear at the top of the fourth tier, with ten points now between first and fourth.
Jones said: "It's nice, it's a real good feeling to be where we are. We have had to earn it as we have had some tough games.
"But we're in good form at the minute and today was a difficult game, I knew it would be a difficult game coming into it. I thought we were excellent and I am really proud of them.
"We earmarked this as a bit of a Notts County game, they're similar in what they do and how they play in terms of the shapes and the intensity they play at. We didn't start well against Notts County and that's a credit to Notts County.
"But we earmarked us starting quickly and we did and we came out of the blocks. Olly Lee had an opportunity, he had one cleared off the line. We had a succession of set-plays which we didn't take advantage of and we were really in the ascendancy. It then took a wonderful bit of play to break the deadlock.
"It was a very tough decision to drop Elliot Lee for James Collins. I didn't leave him out because of his performances, I left him out because of the way we played against Notts County. I didn't want a repeat of that. I wanted to make sure we played into the front and we played off the front and James Collins got a goal and an assist, looking back on it, you think that's not a bad decision."
