RC165 TTL Underwater Strobe, Arm & Fibre Optic Cord Bundle Add a strobe for enhanced detail, colour, and clarity in underwater photos. There’s a simple rule to underwater lighting: more is better. A fast and powerful strobe is the easiest way to improve results beneath the surface. The RC165 delivers a strong, diffused flash that elevates underwater images from dull to vibrant. It is one of the few strobes capable of moving seamlessly from macro to wide angle, providing fast and accurate TTL exposure across a wide variety of camera systems. A Long-Term Lighting Investment Whether the photographer is starting out, upgrading equipment, or downsizing a current setup, the RC165 provides the performance and reliability to support a lifetime of underwater imaging. Trusted by Professionals RC-series strobes have been proven in the harshest environments on Earth — from the Arctic Circle to Antarctica — and everywhere in between. Key Features TTL that works on every shot with compatible camera systems Speed and power suitable for professional-grade performance < li>Large, hard-click dials free of obstruction < li>Perfectly diffused light without the need for a diffuser Daylight-balanced colour temperature for accurate coral, model, and reef representation Ultra-wide 120º beam angle Travel-safe, airline-friendly NiMH rechargeable batteries No-lube, no-fuss positive cam lock Fully compatible with legacy systems Made in the USA Depth rating: 100 m (330 ft) 2-year warranty Light Quality Featuring Ikelite’s proprietary circular flashtube design and soft white powder-coated reflector, the RC165 produces stunning light quality—ideal for professional wide-angle underwater photography. The strobe’s beam is designed for excellent spread and accurate colour temperature without requiring a light-reducing diffuser. For even wider coverage, an optional Dome Diffuser (#4069.2) is available, reducing apparent brightness by only half a stop. Ergonomics Quickly adjust your settings without losing sight of your subject. The large, tactile click-stop dials provide intuitive feedback, allowing for instant exposure changes—even when wearing thick gloves. A slide lock prevents accidental activation during transport. High-Performance Power The RC165 uses custom rechargeable NiMH cells for exceptional power delivery and fast recycle times. Unlike common AA batteries, these cells provide consistent performance—even during high-speed shooting and in challenging underwater conditions. The battery pack is easy to attach with Ikelite’s reliable toggle lock system—no o-ring lubrication required. The RC165 is compatible with both older NiMH Battery Packs (#4066.5) and newer models (#40066GY and #40066BK).
