To have a monolight that is both extremely portable and high in output is hard to find unless you are willing to spend a significant sum of money. The first thing that comes to mind are the Profoto B1s. Before I lose you, no the Flashpoint RoveLights are nowhere near the league of the venerable B1s. However they offer a user experience, albeit flawed, that replicates having an internally-housed battery powered strobe that is convenient to use for on-location portrait work. In the past 4 months, I have taken these lights with me on every assignment whether it be an engagement shoot at the beach or an in-studio headshot session. While I can name a handful of things Flashpoint can do to improve the functionality of these lights, the convenience factor and output makes this a very likable unit.
