Profoto B30: 500 Ws
The Profoto B30 has joined the flash inventory, available as a single head or as a location kit with two heads, two spare batteries, two chargers and an Air Remote. It is a battery monolight with 500 Ws of flash power and an 11 f-stop range, from 0.5 Ws up to full — adjustable in tenths of a stop. In practice that means one light covers everything from a whisper of fill on a face to a main source that holds its own against Mediterranean sun. Three lights in one body The B30 has three flash modes, and they are not marketing labels — each changes what the light actually does: Eco — the default. Recycles from 0.01 to 1.8 seconds, runs cooler, extends the life of the head. This is where the light sits on a normal shooting day. Boost — full power available on demand, recycling 0.01 to 2.1 seconds. Freeze — shortens the flash to 1/21,100 s (t0.5) to stop movement dead. Hair, water, fabric, a jump: this is the mode that makes them readable.
