Ikelite RC165 TTL Underwater Strobe Fiber Optic

Ikelite RC165 TTL Underwater Strobe – Fiber-Optic, Daylight-Balanced Power for Every Dive

Bring reef colours to life and freeze fast-moving subjects with the Ikelite RC165, a compact yet pro-level strobe that jumps effortlessly from super-macro to epic wide-angle. A built-in fiber-optic TTL receiver speaks your camera’s language, delivering perfectly exposed frames shot after shot while you stay focused on composition. With a 120 ° beam, 5 000 K daylight colour and a spot-beam 205 lm aiming light, the RC165 paints subjects in rich, natural tones—no diffuser required.

A custom circular flashtube, soft-white reflector and high-output NiMH battery pack provide lightning-fast recycle times throughout the pack’s charge, so you never miss fleeting action. The corrosion-proof ABS-PC body is more than 230 g lighter than aluminium strobes and is depth-rated to 100 m, making it a travel-friendly workhorse from tropical shallows to sub-arctic wrecks.

Large, glove-friendly click-stop dials give instant, tactile control over 10 manual power levels (½-stop steps) or full TTL automation. A positive cam-lock keeps the battery compartment bone-dry—no lubricant, no drama.
