Part of the expanding OCF (Off-Camera Flash) 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 is 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 includes 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 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 3-grid set that can be used in conjunction with the barndoors.

PortabilityThe 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
