When we started the journey of making the Retra Flash, we had a single goal in mind:

Develop a true lighting tool for underwater photography.

With the 5th generation Retra Flash Pro Max II, we’ve pushed this vision further than ever. Delivering 65% more light output, 25% faster recycle times, and a 120% brighter pilot light, this is the most powerful, refined, and versatile Retra Flash ever made.

We’ve kept the features that photographers love while improving every core element—ensuring that your accessories remain fully compatible and your creative possibilities continue to grow.

The end-result are three new underwater strobes that not only look beautiful, but have all the functionality you need to create stunning underwater photographs with every press of the shutter button.

"This was an instant, no-hesitation upgrade. The light output jumped from 140Ws to 190Ws, the recycle times are faster, and the ergonomics are better than ever. This strobe delivers more power at the top end and less at the low end—making it incredibly versatile. And best of all, all my existing accessories still work perfectly."

Using widely available AA batteries, the Pro Max II delivers Li-ion-like performance while maintaining travel safety and convenience.

• Up to 2000 shots at 25% power in 8xAA configuration
• Booster compatibility for extended sessions and faster cycling
• Built-in leakage detection and double O-ring protection for peace of mind

The power of luminosity and quality of light are very important aspects in underwater photography. That's why we made no compromise when it came to light output and power, when designing the Retra Flash.

The circular flash tube, combined with a completely new reflector design and a frosted dome, produces a high quality light output that no other underwater strobe its size can offer.

The Retra Flash provides softer and more evenly distributed illumination of the subject, delivering stunning results in a variety of conditions.

And with flexible light control you can adjust the intensity of illumination to design your light according to your needs.

The Retra Flash also features a powerful central pilot light ideal for snooting. With a super powerful centrally positioned pilot light you will be able to find your light spot even in very bright conditions.

We wanted to make an underwater strobe that allows its users to have as much control and information on the performance of their strobe as possible. That's why we made the Retra UWT Application (for Android & iOS) that can connect with your Retra Flash via bluetooth.

Retra Flash is the first underwater strobe with smartphone connectivity - made for the 21st century.

The application allows you to check the status of your strobe, providing you with information like current version, number of flashes made, and battery charge levels. You can also customize the light output, set advanced features like HSS, Smart SL, Pilot Adjust and more.

The Retra Flash is also future-proof as you can download firmware updates from the Retra UWT App to keep your Retra Flash up to date.

The new Retra Flash series features the classic bayonet mount at the front of the strobe that enables a variety of accessories to be attached for a truly customizable light source.

With the bayonet mount, your Retra Flash can be transformed into a specialist lighting tool.

The selection of Diffusers change the color temperature, softness and output of the light. You can choose from: White, Soft, Wide angle, and Shark Diffusers.

The Reduction Ring narrows and focuses the light beam. It helps reduce backscatter for macro or low visibility photography. The Reduction Ring is also used as an attachment module for the Macro Rings and Reflector accessories.

The Macro and Super Macro Rings reduce the angle of light for "Macro" and "Super Macro" images. They are perfect for getting up close and personal with your subjects.

The Reflector boosts the light output by +1 F-stop (in water) and narrows the angle of light for more precise light control.

The Bumper Rings are attached to the front and the back of the Retra Flash to protect the edges against damage during rough seas.

The Protective Ring does not impact the size or quality of light. It's main task is to shield the dome from damage.

Over the course of development of the Retra Flash, we put our strobe through rigorous testing to ensure the materials and systems were up to the highest standards.

A combined total of more than 1,4 million test shots were made with prototype and pre-production units of the Retra Flash. We were looking for failure in every condition and pushing the material to its limits. The final result is a product that can withstand anything the photographer asks from it.
