A Fluence light will be a tough fit in that tent except for maybe the Ray22. Same for most of the Amare fixtures.
Strips are a great idea. Or if the OP wants slightly easier assembly, with good light coverage the QB 120 V2 or QB 132 V2 would be a good option. He could technically fit all four boards in his tent, and drive them somewhat softly, or just incorporate 2 or 3 of the 4 boards in the pack. Either the strips or those boards will work in his favor considering the limited height he has to work with.
