Bolt – VB-22 Bare-Bulb Flash

A Guide to On-Camera Flash

Featuring a bare-bulb design and an output of 360Ws, the Bolt VB-22 Bare-Bulb Flash is a specialized shoe-mount flash unit that offers users a quality of light similar to studio strobes in a compact, portable package. The bare bulb design provides a full 360° specular light and is able to work with a variety of optional light modifiers, such as an umbrella mount, colored filters, and grids for creating distinct lighting effects.

The unit features a powerful guide number of 262′ at ISO 100 and covers about 28mm when used with the included reflector. The flash can also be used as an optical slave at a range of up to 33′. This mode has two settings to control whether to trigger the flash immediately when the master is fired or to ignore a single preflash.

The VB-22 flash also features a stroboscopic, or repeat, mode that allows the unit to fire multiple flashes in a row, meaning users can capture multiple images of a subject in a single exposure. The locking head can rotate 135° right and 180° left as well as tilt from -15 to 90° for added control and versatility. Additionally, the unit is fully manual and offers power settings from 1/1 to 1/128. The flash does require power from an optional external power pack which will provide a recycle time of approximately 0.1 to 5.2 seconds. It comes with a retaining ring, diffuser, reflector, power cable, protective pouch, a stand/tripod mount, a stand mounting foot, and a shoe mounting foot.
