I agree that the power supply must be matched to the length of the strip
For the same light,lower voltage means higher current.Higher current requires a thicker electrical conductor.Depending on the construction of the strip there will be a limit where wire heating and voltage drop becomes a problem.What is the maximum length the strip can be?
