The right lighting is more important underwater than the right camera.

The DS165 is your gateway to professional-quality underwater photography, suitable for systems ranging from compact point-and-shoot to full-frame mirrorless. Simple to use with a compact design, it features a travel-friendly nickel metal hydride rechargeable battery pack.

A great strobe is your best investment—providing flexibility to adapt to any shooting scenario and compatibility with TTL systems from Canon, Nikon, Sony, Panasonic, Olympus / OM System, and Fujifilm.

Trusted by professionals worldwide, DS-series strobes are proven performers in the harshest conditions on Earth—from the Arctic Circle to Antarctica and everywhere in between. They remain the long-standing choice of professionals who rely on consistent, repeatable performance.

Light Quality

Featuring Ikelite’s proprietary circular flashtube design and soft white powder-coated reflector, the DS165 produces professional-grade light quality—ideal for wide-angle underwater photography.

The beam is designed for excellent spread and accurate colour temperature without requiring a light-reducing diffuser. The optional Dome Diffuser (#4069.2) is available to further extend beam spread with only a half-stop reduction in apparent brightness.

Ergonomics

Quickly adjust settings without taking your eyes off your subject. The large, tactile click-stop dials allow instant exposure changes—even when wearing thick gloves. A slide lock prevents accidental activation during transport.

High-Performance Power

Driven by custom rechargeable NiMH cells, the DS165 delivers fast, consistent recycle times and high frame rate firing. These premium industrial-grade cells outperform AA batteries in demanding underwater conditions—including temperature fluctuations and storage challenges.

The battery pack attaches easily via Ikelite’s reliable toggle lock system—no o-ring lubrication required. The DS165 is compatible with both older NiMH Battery Packs (#4066.5) and newer models (#40066GY and #40066BK).
