Rouge Pro G4 vs Rouge Ultimate G4
The Pro G4 is the cheaper of the two at $1,121, so it wins on value if the specs are close enough for your use. The Ultimate G4 packs more emitters (1152 against 288), which usually means a shorter session for the same dose.

Pro G4
Rouge discloses more honestly than almost anyone, publishing both measurement methods with distances. Even so, an independent tester came in a third below their own spectrometer number.
Ultimate G4
The widest spectrum and largest panel available, but spreading output across eight bands means less of each than a focused two-wavelength panel delivers.
