Featuring a bare-bulb design and an output of 180Ws, the Bolt VB-11 Bare Bulb Flash Kit with PP-500DR Power Pack from B&H 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 196' 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-11 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. It comes with a retaining ring, diffuser, reflector, power cable, protective pouch, and a stand/tripod mount.
Working with the included PP-500DR Dual Outlet Power Pack the VB-11 will allow a very fast recycle time to full power in just 1 second! The power pack has two outlets for powering two flashes simultaneously and works with most flash units featuring HV power ports. Also, the PP-500DR's flash cable ports can be locked once the cable is attached, making the connection extra-secure. This pack is powered by a rechargeable battery and has four LEDs for determining charge. Additionally, it has a belt clip and comes with a shoulder strap.
