In our tests, the Interfit managed to match the maximum light output of the Elinchrom 400Ws head and even the Bowens 500Ws head, while also edging ahead of the Lastolite 400Ws one. However, recycling time after a full-power flash is the slowest, at two seconds. For wider-aperture or shorter-distance shooting, the Interfit also matches the Bowens in giving the joint least illumination of the flash heads at its minimum power setting. Like most flash heads at this price point, the Lumen8 is available on its own or as part of a twin-head kit.
