The Retra Flash Pro Max is our new high-end underwater strobe equipped with cutting-edge underwater lighting technology, delivering top tier performance for any style of underwater photography.

The Retra Pro Max is our most advanced strobe and has unique features like the backlit display for easy to read control settings and smartphone connectivity with advanced customizable user modes via the Retra UWT application. The new and improved triggering system is the most efficient system we have ever made, allowing the Pro Max to achieve a higher light ouput with less power consumption, while the circular flash tube ensures softer and more evenly distributed illumination. The Pro Max also features a new battery compartment design optimized for ease of use. The classic bayonet mount at the front of the strobe remains the same as on previous versions so all existing Retra accessories are compatible.


The Retra Flash Prime + is our mid range strobe that features a circular flash tube for softer and more evenly distributed illumination and offers more control over the intensity of light output.
This makes the Retra Flash Prime + perfect for almost any lighting condition and can be adjusted to fit any style of underwater photography. The Prime + strobe also features a new and improved control panel design and battery compartment, optimized for the best user experience. The classic Bayonet mount is compatible with all existing Retra accessories.


The Retra Flash Pure is a new addition to the Retra Flash family. The Pure is our entry level strobe, designed for anyone looking to dive into the world of underwater photography.

Retra Flash Pure features basic control functions (without HSS mode) and has 70 Ws of power with evenly spread light output. The built in short circuit detection system warns you if there is any serious issue with the electronics or batteries. It also features an improved battery compartment design and the classic bayonet mount for attaching all existing accessories.
