The separately-purchased B2 head is small and light enough to be put on a bracket on your camera as well as a monopod or stand. Intended for the road, the pack measures 6.3 x 3.1 x 6.7" and weighs in at just 2.2 lb with its optional Li-Ion battery. An entire B2 kit fits in a bag no larger than your average shoulder bag
At full power, the B2 250 AirTTL power pack with its separately-purchased flash head recycles in 1.35 seconds. In Normal Mode, which prioritizes color fidelity, the B2 offers flash durations of 1/1,000 sec. while Freeze Mode gives you flash durations as short as 1/15,000 sec. at lower power settings for dramatic action-stopping shots. At lower power settings there's also a burst mode that allows triggering of up to 20 frames per second
The Li-Ion Battery for B2 Power Pack from Profoto is the power source for the B2 Battery Pack. The battery offers 215 full-power flashes on a 45-60 min charge from an optional 2.8A charger. The battery has an LED gas gauge type power status indicator and a rubberized base.
In what is starting to seem like an annual event, Profoto has once again introduced a breakthrough product. This time it is the B2 OCF Flash Head. Part of the expanding Off-Camera Flash (OCF) System, which includes the B2 250Ws battery pack that drives it, the B2 head has its own line of lightweight, custom-made light shapers that are also compatible with the other member of the OCF family—the B1 Off-Camera Flash.
Weighing in at just 1.5 lb, the sturdily made B2 head measures 4" long, has a 3.9" diameter, and fits in the palm of your hand. A barely visible umbrella channel runs through the top of the head, while its tethered 6.5' head cable can be lengthened with a 9.8' extension for large groups or for hanging in hard-to-reach places. An included stand or pole-mount with a ratcheting handle can be removed for mounting to a flash bracket. The B2's flash tube and 50W halogen-equivalent LED modeling lamp are protected by a frosted glass plate, while its 3.9" diameter housing accepts a new line of optional accessories that include 1.3 x 1.3', 2x3', and 1x3' softboxes and a 2' octa box. The speedring for the softboxes has be scaled down and fitted with an easy snap-in system for the poles, while the hard rubber collar has been replaced with easy-slide silicone. All accessories in the OCF family also fit the B1 Off-Camera Flash.
Also worth mentioning are the four-way barn doors with gel clips, a snoot, and 10/20/30-degree three-grid set that can be used in conjunction with the barndoors.
The B2 head is small and light enough to be put on a bracket on your camera as well as a monopod or stand.
The B2 offers full TTL operation with both Canon and Nikon cameras via the optional Air Remote TTL-C or TTL-N transceivers. Just point and shoot—the B2 will automatically adjust its light output to provide you with the right exposure.
The B2 is designed to help you to add a little or a lot of extra light wherever it is needed. The entire B2 kit fits in a bag no larger than your average shoulder bag.
At full power, the B2 head with its separately purchased power pack recharges in 1.35 seconds. At lower power settings, it will produce up to 20 flashes per second, catching even the most fleeting gestures.
The built-in reflector renders a wide, even light spread that can be modified with any of the more than 150 optional light-shaping tools available.
The Battery Charger 2.8A for B1 and B2 500 AirTTL from Profoto will charge the B1's and B2's Lithium-ion batteries in 2 hours. This multi-voltage charger features LED indicators to easily monitor charge status.
The Carrying Bag for B2 Off-Camera Light from Profoto is a thick neoprene, form-fitting case that holds and protects the B2 250 AirTTL with a mounted Li-Ion Battery. It features a belt loop, an adjustable shoulder strap, and a short strap for hanging the pack from a light stand or other support.
Two bags in one, the black B2 Location Bag for B2 Off-Camera Flash System from Profoto is a padded nylon case with top-zippered closure, a compartment for the B2 Power Pack, and two removable padded shells for B2 flash heads. The case can hold all the above plus a charger, extra battery, and a head extension cable.
The second part of the bag consists of a removable nylon shell for encasing the padded bag within. It measures approximately 16 x 9 x 9" and features top-zippered closure, handles, a shoulder strap, and topside straps for poles, monopods, or stands. An exterior pocket runs the full length of each 16" side.
