Wells comes to Kenilworth Road after five-and-a-years at Ashton Gate, where he was a member of the squad who reached the Championship play-offs last season before losing to Sheffield United over two legs in the semi-finals.
He is a Bermuda international and has scored 174 goals in English football, with Luton boss Matt Bloomfield saying: “He’s someone with extreme know-how and a real desire to still go and score goals, a real desire to go and achieve something and a real desire to be a part of what we are building.”
Odoffin, 27, left Rotherham in May after four years in South Yorkshire and Bloomfield said: “Hakeem is a real leader and someone I’ve been aware of for a number of years. He is someone who we feel can have the personality and character to have a real impact for us.”
Lonwijk’s loan deal could become permanent if “certain criteria” are met and he is reunited with Bloomfield, who he previously worked with during a loan spell at Wycombe Wanderers in 2024.
The 22-year-old Dutchman was previously on loan at Plymouth Argyle when they won the League One title in 2022-23, and has also had loan spells at Fortuna Sittard, Grasshopper and Huddersfield Town.
