The 400 watt strobe is a good mid-range strobe, good for studio work and larger scale on location shoots alike. It is high quality and easy to adjust, both in position and brightness. It can act as a slave, making this strobe easy to use in any environment. The included battery pack makes it possible to do on-location photo shoots where there is no power supply available. The included metal carry case makes for worry-free transportation to and from your photo shoots.
