The 500Ws light has a 10-stop variable power range and swift recycle times of 0.05 to 2.5 seconds. Freeze Mode, which prioritizes flash duration yields a very short 1/50,000 second at minimum power. The B10 Plus is powered by a lithium-ion battery that gives you 200 full-power flashes on a 90-minute charge, while 60 minutes will top up the battery to 80% if you're short on time.

Main power controls for each head are top and center. Levels can be set in 0.1 stop increments with a flick of each knob, or in full stop increments by pushing down and turning each knob. Default readout is in stops, with "10" being full power. Readouts may be seen temporarily in Watt/Seconds with a push of a button. Secondary controls for the modeling light, radio slave, recycle speed and audible recycle tone are visible from the top, but controlled from the sides.
The truly impressive features of this 2400 watt/second power pack are found in its performance. The 8a Air has extremely short recycle times which allow it to fire up to 20 times a second (stroboscopic). Power and color fluctuations are not visible in the image to the human eye (±1/50 f/stop and ±40°K flash-to-flash, respectively). The power levels may be controlled from the optional Profoto Air transceiver and/or the optional USB transceiver, from your Mac or PC.
The Pro-B4 is a state of the art battery pack that in some regards outperforms even the best studio packs out there. It’s a revolution on location and unique in that it’s a battery pack that can freeze motion at 1/25,000 a second and fire up to 30 flashes in a second.
