Light Quality

Our proprietary circular flashtube design and soft white powder coated reflector produce a quality of light that is widely accepted as the perfect choice for professional wide angle underwater photography.

A custom formulated ABS-PC blend make the strobe fundamentally corrosion-proof and over 1/2 lb (237 g) lighter than aluminum-body strobes.

The DS165 beam is designed for proper spread and color temperature without adding a light-reducing diffuser. The optional Dome Diffuser # 4069.2 is available to extend the spread of the light with only a half-stop reduction of apparent brightness.

Ergonomics

Change settings quickly without taking your eyes off the subject. Life moves quickly underwater and you need to be able to react instantly when your lighting needs change. Shooters who use manual strobe exposure settings prefer our large, click-stop dial controls which provide intuitive, tactical feedback of exposure setting.

The robust dial controls are now even larger and taller for comfortable use with even the thickest gloves. A slide lock prevents the strobe from accidentally being turned on when not in use.

High-Performance Power

Your strobe is only as powerful as the batteries that drive it. Commercially available batteries do not have the low internal impedance required for truly fast recycle times. Even the best rechargeable AA batteries are sluggish in high-powered strobes and only get slower and weaker as their charge drains.

Our custom rechargeable cells power high frame rate firing from the first shot to the last. These premium quality industrial grade NiMH cells have been proven to out perform alkaline and lithium cells in real world underwater conditions, including the temperature fluctuations and storage conditions of the photographer diver. While 5 years is the average lifespan of a rechargeable pack, we routinely talk to shooters who are happily using 10-15 year old NiMH battery packs.

The battery pack attaches quickly and easily with a unique toggle lock that prevents accidental floods. You don't even need to lubricate the o-ring. The strobe front is compatible with older NiMH Battery Packs # 4066.5 or the newer Battery Packs # 40066GY and 40066BK.

A Name to Trust

Ikelite was the first to introduce these underwater strobe technologies which are considered standard today: aiming lights, interchangeable cords, removable battery packs, smart charging, battery power indicators, wireless TTL slave sensors, built-in video lights, and TTL communication with digital cameras.

We have the longest track record in the design and manufacture of professional strobe lighting for underwater use. We offer the only underwater strobes designed and manufactured in the USA and distributed worldwide to over 95 countries.

TTL Compatibility

This strobe supports fiber optic TTL triggering with compatible cameras and TTL transmitters. Manual fiber optic triggering is supported with all other systems.
