Profoto B1 flashes are one of the best light modules on the market of flashes with the power above 500W and one of the most widely used ones by photographers. The B1 model's successor – the B1X model – has a really impressive specification.
ProFoto B1X is equipped with 80% brighter LED modeling lamp, 50% more capacious battery (thanks to which we can make 325 flashes with full power), the support for TTL measurement and the HSS mode (which enables synchronization with the shutter speed up to 1/8000s). All of this is embodied in the housing having the dimensions of 12.2x5.12in (310x130mm) (Length x Diameter).
