New Pro-B4 1000 Air
The design team at Profoto was asked to come up with a battery generator that would redefine on-location lighting, and they came up with the Pro-B4 1000 Air
“We had a clear goal when we first started working with the Pro-B4,” says Göran Marén, Product Manager at Profoto. “We wanted to build the fastest, toughest battery generator there ever was. We wanted to change the game.”
The Pro-B4’s most prominent feature is its flash duration; due to the new, patent pending Hybrid Capacitor Technology, the Pro-B4 is said to deliver flash durations down to 1/25,000 of a second. This is said to be the shortest flash duration of any battery generator in the world and also of any flash pack.
The Pro-B4 is also said to be the world’s fastest recycling battery generator. At lower power settings it is apparently able to fire up to 30 flashes per second, while the longest wait on full power is said to be less than a second.
The energy setting is adjusted with control in 1/10 f-stop increments. The display can be set to show the output in f-stops or watt seconds, and information about the flash duration on each head is easily accessible.
The powerful Li-Ion battery can fully recharge in less than 45 minutes and can be recharged while in use. This means that if the modelling light is used moderately, the pack should be able to be used continuously while connected to a mains outlet.
The Pro-B4 has a solid-cast aluminium chassis and the rubber frame should ensure that it can withstand knocks and bumps. All connections have protective lids and the pack has no air vents, which helps prevent water or dust from getting inside.
