Ikelite RC165 TTL Underwater Strobe, Arm, and Fiber Optic Cord Bundle

The Ikelite RC165 TTL Underwater Strobe, Arm, and Fiber Optic Cord Bundle delivers professional-grade underwater lighting performance in a complete flash kit. At its core is the RC165 TTL strobe, which produces powerful and perfectly diffused flash light for vibrant, richly colored underwater photos from macro to wide-angle realms. Its fiber optic TTL triggering works with compatible camera systems for fast, accurate automatic exposure, while manual flash control across multiple power levels lets photographers dial in precise lighting when needed.

Constructed from corrosion-resistant ABS-PC material, the strobe body is significantly lighter than traditional aluminum strobes, yet rugged enough for demanding underwater environments. Large, glove-friendly click-stop knobs allow quick setting changes even with thick gloves, and a positive toggle lock keeps the NiMH rechargeable battery pack securely sealed without the need for lubricant.

The included arm and fiber optic cord make mounting and triggering simple and reliable. The light’s daylight-balanced color temperature (approximately 5000 K) and ultra-wide beam pattern ensure excellent illumination for both reef scenes and close-up subjects. With a 100 m depth rating and a 2-year warranty, this bundle is engineered for both recreational and professional divers who demand consistent, high-quality flash performance.
