In the Box
I often need several strobes for my work in underwater caves. Ikelite has always offered a robust build, high power and reliability. That is very important to me in the field.
I have been shooting Ikelite strobes for over 40 years. 95% of my library of over 300,000 images have been shot with Ikelite strobes. The remaining 5% are available light. The clean wide angle of coverage of these strobes have been essential to my success with these images.
I’ve spent months shooting underneath the Antarctic ice in the past 20 years, including filming for the BBC Life series. Ikelite strobes have been the only ones I found to be dependable enough for professional use in the harshest conditions on Earth.
In a trip to the Revillagigedo Archipelago, I was fortunate enough to witness hundreds of the ocean's top predators and nailed each shot time and time again. With quick recycle times and accurate TTL, the only time I touched my strobes was to adjust position and paint the light the way I wanted it in a scene.
Ikelite strobes have illuminated pictures in all my 38 books of the ocean and over 500 of my features in magazines. As a working professional, I have tried and tested many other brands, Ikelite is the finest in its class bar none.
Upgrade Your Housing
Breathe new life into any camera system
Want to ditch your electrical sync cords for fiber optic? While they're equally reliable, fiber optic cords have the added advantages of being thinner, lighter, and are able to be taken on and off while wet - or even underwater. If your Ikelite housing is gray and features an electrical flash bulkhead, you can upgrade it easily yourself for fiber optic triggering.
