The PIXAPRO STORM III 400 (Godox QT400 IIIM) is a 400Ws High-Speed Studio Powerful Stroboscopic Flash that uses Insulated-Gate Bipolar Transistor (IGBT) technology to achieve extremely short flash durations of up to 1/29,600 of a second, as well as ultra-fast recycle times enabling you to shoot at up to 20 Frames Per Second. This allows you to capture perfectly sharp images of fast-moving subjects such as dancers, sports personalities and even water splashes with the greatest ease. It also features a Bright Built-in 40W LED modelling lamp, enabling you to easily preview your lighting better than ever before. Featuring a built-in 2.4GHz receiver and a variety of different flash modes including High-Speed Sync (HSS) Rear-Curtain Sync and Multi-Flash mode. it is perfect for people who shoot Sports, Action, Dance, Fashion, Food, Product and Advertising photography. It is especially good for photographing children.

Capture Motion Like Never Before - High-Speed Flash 

The STORM III 400 utilises Insulated-Gate Bipolar Transistor Technology (IGBT) to enable it to produce high-speed super-fast flash durations of up to 1/29,600 of a second (T0.1), enabling you to perfectly freeze fast-moving subjects with perfect sharpness. Great for photographing water splashes, powder and more.

Phenomenal Speed

The STORM III 400 features super-fast recycling times, enabling you to shoot at rates of up to 20 frames per second, ensuring that you will never miss the perfect shot. Ideal for photographing dancers, and sports personalities.

Stroboscopic Flash Mode

The Stroboscopic flash feature enables you to capture motion in a unique way. It works by firing multiple flash-bursts in rapid succession. When combined with a slow shutter speed, it enables you to capture amazing images of your subject in motion in a single exposure, as shown in the image below.

High-Speed Sync Mode

The Pixapro STORM III 400 features a Hight-Speed Sync (HSS) mode, which enables you to synchronise your flash at higher shutter speeds than what is normally possible (up to 1/8000 of a second). This mode is useful for times when you would like to shoot at wider apertures, or if you need a faster shutter speed to kill any excess ambient light in your scene.

Rear-Curtain Sync

The Pixapro STORM III 400 features Rear-Curtain Sync, which enables you to capture stunning motion-trail effects when paired with slow shutter speeds. This mode causes the flash to fire at the end of the exposure, as opposed to the start, producing natural-looking motion blur effects, that appear behind your subject. With standard front-curtain Sync, the motion-blur effect appears in front of your subject which can look a little strange in your final image.

Stable-Colour Mode

The Pixapro STORM III 400 features a Stable-Colour Mode, to ensure that you get as little colour-temperature variation between different flash powers. This is especially useful when shooting colour-critical work such as for Advertising, Fashion Lookbooks, Product Catalogues etc.

LED Modelling Lamp

The STORM III 400 High-Speed Flash now features a built-in 40W LED Modelling lamp, (which is approximately 1.3-stops brighter than the older 150W halogen modelling bulbs). LED modelling lamps are brighter, run cooler and are more energy-efficient than traditional Halogen lamps. They also have a considerably longer lifespan. This makes the STORM III 400 safe to use with modifiers that enclose the bulb such as snoots, without you having to worry about the modifier becoming too hot to handle.

Power and Precision at Your Command

The Storm III 400 features an improved 9-Stop power range, enabling you to adjust the power anywhere between full and 1/256 power in increments of 1/10 of a stop. Whether you want an intense burst of light for use as a main light or a subtle kiss of light, the STORM II 400 s guaranteed to deliver.

Pixapro ONE System Compatible

The STORM III 400 features a built-in receiver that is fully compatible with the Pixapro ONE flash trigger system (GODOX X System). This enables it to be triggered by any of the PIXAPRO ONE System flash triggers, including the ST-IV (GODOX XPro) ST-III (GODOX X1) and the ST-III+ (GODOX X2) flash transmitters. These triggers are available for Canon, Nikon, Sony, Fuji, Olympus & Pentax with full control. They also have partial compatibility with some high-end cameras, such as Hasselblad, Leica and PhaseOne. 

S-Type Accessory Mount

The PIXAPRO STORM III 400 features the ever-popular Bowens S-Type accessory mount, enabling it to be used with a wide range of different light modifiers such as Softboxes, beauty dishes, reflectors, and snoots, making your creative lighting possibilities virtually endless.

An extensive range of light shaping possibilities are also available through the lightweight and easy-to-use modifier family and other creative light shaping tools in the PIXAPRO range.

The PIXAPRO® STORM II 400 High-Speed Flash is the perfect studio strobe system for photographers who like to shoot fast-moving subjects, such as Dancers, Athletes, and Children, as well as creative photography such as Water splashes, and powder. This easy-to-use flash has many features suitable for both amateur and professional photographers. An essential addition to any photographic studio’s lighting arsenal.
