The Profoto B2 250W/s AirTTL Location Kit features 250W/s of flash power distributed asymmetrically over a 9-stop range in full or 1/10 steps across the two heads. This kit's batteries can be charged in or out of the pack and give you up to 215 full power flashes on a 45-60 minute charge. Shooting bursts of up to 20 FPS can be achieved with this kit in High Speed Sync mode allowing for shutter speeds up to 1/4000th-1/8000th of a second. There is an umbrella shaft slot in each of the heads as well as a stand mount and ratcheting handle that can be removed for adding your own flash bracket onto one of the heads for on-camera mounting. These heads are compatible with Profoto's light modifiers up to 5' in the octagonal shape and up to 4' for the rectangular shape softboxes. These heads can also accommodate Profoto speedrings. Each head is fixed to a 6.5' cable that connects to the pack. This is a fully portable kit that is perfect for on-location shooting where AC power isn't readily available. Its wide range of power settings makes this kit suitable for studio and outdoor shooting and is perfect for portraits, action shots, lifestyle photography, and event shooting.
