Product Information

To see a behind the scene and customer review of the RIKO400 Portable Flash Please see the videos below, these reviews were made by Tommy Reynolds:

PLEASE NOTE: This video is not full a representation of what is included in this listing as some items are used for demonstration purposes only. Please see the “Specifications” tab for information on what this listing includes.

The PIXAPRO RIKO400 (Godox Wistro AR400), is a 400Ws Ring Flash that enables you to mount your camera directly onto it to provide your subjects with soft, near shadow-less illumination, giving your portrait photos a more edgy-fashion look.

RIKO400 has an 8-Stop power range (1/1 - 1/128) and features 2x slave modes (S1/S2). It uses an array of LED lights that act as a continuous modelling light. It also features a stroboscopic flash mode, and a high-speed sync mode for more creative shots.

RIKO400 is equipped with folding bracket, which enables you to mount your camera directly onto it. The RIKO400 can also be used off camera for off-axis lighting, giving you an effect similar to that of a beauty dish. It also comes with an umbrella bracket, which enables the RIKO400 to be used in conjunction with an umbrella for a wider spread of light.

Unlike most other Ring Flashes on the Market, where you have to plug the Ring Flash into an external Battery Pack, the RIKO400 uses a replaceable 11.1V/4500mAh internal lithium battery pack, which will give you approximately 450 Full-Power flashes per charge. The battery charger is also included with the RIKO400.

The Riko400 is also compatible with the PIXAPRO Pro AC wireless flash trigger (sold separately), which enable you to control the flash’s power output and other functions of the Ring Flash remotely.

The Riko400 Ring Flash is the perfect light for adding a unique look to your portrait photography.

PIXAPRO® RIKO400 Portable Ring Flash (AR400)

Powerful and versatile light, perfect for a specific need. Recycle times are impressive so far. A little cumbersome but that is the same for all ring lights.

PIXAPRO® RIKO400 Portable Ring Flash

very nice product just miss real filter to diffuse light a bit to strong

Good .... But....

This ring flash unit is good & well built but the actual flash ring aperture quite small and can be difficult to mount F1.8/2.8 lens. For example the Tamron 85mm F1.8 on a Nikon D810 with the lens through the aperture you can't actually get your finger around the grip of the camera, so then you need to have a lens hood attached to the lens to avoid flare (due to the flash being slightly forward of the lens) this could only be achieved by removing the diffuser. In all, I get great results but I find it frustrating to set up with a prime or zoom lens.

PIXAPRO® RIKO400 Portable Ring Flash

This lamp is very mobility. Can be use in softbox also portraits photography.

Very good value for money

I have recently purchased this ring flash, and my first impressions are great. I currently own a Bowens Ring Flash which is about the same weight but needs a heavy power pack to use it. This ring flash while rather large in the hand with a pro camera is easy to use and gives excellent portable power.
As an added extra it can be used as a stand alone studio flash using the small bracket supplied which can be used on a studio lighting stand using a brolly, as the output of 400 joules far outshines any speed light I have used for off camera work.
Its early days with it, but so far I'm very impressed with the unit and the amount of flashes you can get from it on one charge. I have bought an extra battery for around £50 off Ebay as a backup and to get more shots on a shoot.
The only downside as I can see so far is that the battery is very stiff when trying to remove it, this may be down to the newness of the item and could slacken off with regular use.

Questions & Answers


By default, the ST-IV or ST-III won’t trigger the flash if placed within very close proximity to your flash (normally within approximately 30cm or so). Since the RIKO400 ringflash is generally used on-camera, which is too close for the ST-III or ST-IV to trigger. You can however, switch your ST-IV or ST-III to 0-30m mode, wich will enable you to shoot at very close proximity.

With the ST-III, please ensure that your ST-III trigger is updated to at least the following versions: (ST-III C - V15, ST-III N - V16, ST-III S - V13). Now Press and hold the "TEST" button whilst switching the ST-III trigger on, until "STATUS" light blinks for 2 seconds. 0-30m mode should now be active.

With the ST-IV, simply go into the C.Fn menu, select the "DIST" option, then set it to 0-30m.


Yes it does. The RIKO400 has both a 3.5mm Sync jack, and a PC Sync port, as well as a USB port for the PIXAPRO PRO AC Series Flash Receivers.


In order for High-Speed Sync (HSS) to work You have to switch your Riko400 Ringflash to a certain mode.

If you press and hold the two buttons simultaneously (the two buttons circled in the photo below), it should switch to HSS mode. (You will know when It’s in HSS mode when you see “H” symbol on the display (show by the arrow in the photo below).

Please Note: HSS Mode on the RIKO400 requires the Pixapro PRO ST-II High-Speed Transceiver Set to Operate, Which are available for both Canon and Nikon cameras
