Godox QT400IIIM Pro High-Speed Studio Flash Head with LED Modelling Lamp

Godox GD-QT400IIIM (GD/QT400IIIM, GD_QT400IIIM, GDQT400IIIM, GD QT400IIIM) QT400IIIM Pro High-Speed Studio Flash Head with LED Modelling Lamp

The Godox QT400IIIM is a 400Ws Professional High-Speed Sync Studio Flash Strobe Light 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. It features 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.

The Godox QT400IIIM uses Insulated-Gate Bipolar Transistor Technology (IGBT) to deliver ultra-fast flash durations up to 1/29,600 of a second (T0.1), ideal for freezing motion like water splashes or powder with sharp detail.

Phenomenal Speed

The QT400IIIM 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 creatively by firing multiple flashes 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 Godox QT400IIIM studio strobe light features High-Speed Sync (HSS), allowing flash use at shutter speeds 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 Godox QT400IIIM 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 QT400IIIM flash strobe light includes a stable-colour mode, minimising colour temperature shifts across different power levels—ideal for colour-critical work like advertising, fashion lookbooks, and product catalogues.

LED Modelling Lamp

The Godox QT400IIIM high-speed sync 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 QT400IIIM 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.
