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.

The Cyclone DR PP-400DR Dual Outlet Power Pack from Bolt features dual plugs for powering 2 flashes at the same time. It works with most on-camera flash units with high-voltage (HV) connections, including those from Nikon, Canon, Sony, Bolt, Sunpak, Quantum, Vivitar, and Metz (cables required and sold separately). The pack has a fast recycle time of approximately 1 sec and provides up to 1400 full-power flashes, depending on the flash and settings used. The Cyclone DR's flash cable ports can be locked once the cable is attached, making the connection extra secure. The unit weighs a mere 1.2 lb.

The power pack's microcontroller unit prevents overheating via integrated software and hardware protection. The included PP-400BP Cyclone DR Battery Pack is removable, allowing you to charge it while powering the Cyclone power pack with a second identical battery (sold separately). Also supplied is a 2-prong 100-240 VAC charger for worldwide use. Four LED's indicate remaining battery charge; one light on means 25% or lower, two lights mean 25-50%, three mean 50-75%, and all four mean 75% or higher. Additionally, the Cyclone DR comes with an adjustable neoprene shoulder strap that has a non-slip rubber underside and a quick-release buckle. It attaches to the strap lug on the power pack. The Cyclone also features a built-in belt clip, as well as two rubberized feet for stability.

The Bolt Grid and Filter Kit is designed for use with the VB-series bare-bulb flash units and comes with a 50° grid for limiting light spill and increasing contrast as well as red, yellow, blue, and green filters for creating accent lighting. These accessories easily mount the flash's reflector and use the retaining ring to remain secured in place. The filters can be stacked for creating different effects.

The Bolt PP-DC Doubler Cable allows you to plug one power cord into two 4-pin DIN HV power pack outlets. This will cut recycle time in half and ensure that the flash is ready to fire when you need it.

Repeated high-power flashes may raise the temperature of the flash or battery unit due to the high-speed recycling. Use caution to avoid overheating and allow your flash unit to cool down periodically.

The Bolt PP-SC Splitter Cable allows you to power two flashes from one 4-pin DIN HV power pack socket, such as those found on the Bolt Cyclone PP-400DR.

Easily mount your power pack to a light stand or attach a multitude of other items where you need them by using the versatile PP-MCX Mounting Clamp from Bolt. The clamp opens from 0.1-1.8" for use on light stands, tables, desks, doors, and other flat surfaces and it features a belt clip slot that allows users to easily hang their power pack. On the back two 1/4"-20 threads at different angles and one 3/8"-16 thread are available for mounting lights and other accessories. To prevent damage, the clamp features a rubber coating and it has the ability to hold up to 2 lb of gear when attached to a light stand or 8 lb on a flat base.

This 15' Extension Power Cord from Bolt is used to connect your VB-series flash to a power pack. This 15' cord provides you with a much further reach than the standard cable.

This Bolt Snoot Set is designed for use with VB-series bare-bulb flash units. It comes with cone and tube snoots, each featuring a built-in 40° grid to assist in focusing light and limiting spill. The cone-shaped snoot creates a tighter pinpoint light with rapid falloff while the tube creates a spotlight with moderate spill. Each unit is mounted via the flash's accessory mount.

The PP-400BP Cyclone DR Lithium-Ion Battery Pack from Bolt powers their Cyclone DR PP-400DR Dual Outlet Power Pack. It has an output voltage of 11.1 V and a capacity of 4500 mAh. The battery is identical to the one included with the power pack, so you can charge one while powering the Cyclone with the other. Use the 100-240V AC charger that was supplied with your power pack.

This Bolt Beauty Dish and Grid Kit is designed for use with the VB-series bare-bulb flash units. It features a 12" diameter beauty dish that will create a soft, yet crisp light source as well as a 40° snap-in grid for increasing contrast and limiting light spill. The dish easily slips onto the flash's accessory mount and comes with a diffuser sock that uses an elastic rim to remain in place on the dish. The sock can be used with or without the grid in place.

This Bolt Umbrella Mounting Kit is designed to allow for the use of umbrellas up to 45" on a VB-series bare-bulb flash unit. It works with shafts up to 8mm thick and features a wide angle reflector with a pass-through mounting hole for ensuring the light will completely fill larger umbrellas. Additionally, the umbrella bracket attaches easily and securely with a thumb screw on the flash head.

The RR-16-A Remote Flash Receiver from Bolt is an advanced 16 channel, 16 group radio triggering device that can fire your compatible remote flash at sync speeds up to 1/250 second at distances up to 150' as well as control its power level.

Operating on the 433 MHz frequency and powered by the host device, the receiver, when used with its separately purchased Bolt RT-16 transmitter, can raise and lower the power of the slave flash in 1/10 or 1/3 stop increments as well as turn modeling lights and audio alerts on and off. It's also capable of turning the AF assist on or off on flash units that have this feature.

The RR-16-A Remote Flash Receiver is compatible only with Bolt VB-11 and VB-22 bare bulb flash heads, Interfit Strobies and Flashpoint StreakLight flash heads.

The Remote Transmitter from Bolt is an advanced 16-channel, 16-group radio triggering device that can fire your compatible remote flash at sync speeds up to 1/250 sec. at distances up to 150' as well as control its power level.

Compatible with the Bolt VB-11 and VB-22 flash heads, the 433 MHz transmitter can raise and lower the power of the slave flash in 1/10 or 1/3-stop increments as well as turn modeling lights and audio alerts on and off. It's also capable of turning the AF assist on or off on flash units that have this feature. It is also compatible with Interfit Strobies flash heads. The transmitter runs on 2 AA batteries and works with the separately-purchased RR-16-A receiver which is powered by the host slave flash. The transmitter can also be used as a handheld central remote controller to adjust the settings on the lights mentioned above, even if you use a different device or method to trigger them.
