160 watt-seconds of manual flash power with 1.6-second recycle and ~400 flashes per charge. 140° coverage angle for wide-angle setups — no light fall-off at the edges. Full manual control for predictable, repeatable exposure. 100m depth rated.

160 watt-seconds. 1.6-second recycle. ~400 flashes per charge.

The KR-S160 is Kraken’s flagship underwater strobe — a fully manual unit built for underwater photographers who want maximum power and predictable, repeatable results. Like the KR-S80, it’s manual-only, which is exactly what experienced underwater shooters want: you dial in your power, it fires at that power, every time. No hunting, no guessing.

160Ws puts the KR-S160 in the power range of strobes that cost significantly more. The 1.6-second recycle to full power is fast for this output level — fast enough for most wide-angle and macro shooting situations. At ~400 flashes per charge on the integrated battery pack, you can shoot an entire dive day on a single charge.

The circular flash tube produces even, wrap-around illumination with soft edges — no hot spots, no hard shadows. The 140°+ coverage angle (without diffuser) works with most wide-angle and fisheye lenses, and the included dome diffuser widens that further for ultra-wide setups.

The built-in 500-lumen spot LED (15° beam) doubles as a focus light for low ambient conditions, and is independently controlled. It’s dimmable across 2 brightness levels — useful for aiming and previewing your coverage before you fire. The narrow beam gives you a precise aiming point without flooding the scene with white light.

Multi flash mode gives you rapid sequential firing for creative effects — a feature the KR-S80 doesn’t have.

Key Features:

• 160 Ws, Manual Power Control: 7 levels (40 Ws, 80 Ws, 160 Ws with 9-step fine adjustment across the range). Rotary dial — straightforward to adjust mid-dive.
• Fast Recycle: 1.6 seconds to full power (160 Ws). Quick enough for most wide-angle and macro work.
• ~400 Flashes Per Charge: Integrated 4000mAh 7.2V lithium-ion battery pack with USB-C charging. No loose cells to swap — charge the whole pack between dives.
• S1 / S2 Optical Slave Modes: Syncs optically with your camera’s internal flash or another strobe as master. No sync cord required if your housing supports it.
• Multi Flash Mode: Rapid sequential firing for creative effects — double exposures, stroboscopic motion, and experimental techniques.
• 500-Lumen Spot LED: 15° narrow beam, independently controlled with 2 brightness levels. Precise aiming light that doesn’t flood the scene.
• Fiber Optic Port: Sea & Sea cable port + M11 threads + 7mm hole port. Compatible with all standard sync options.
• 180° Rotatable OLED Display: Clear, readable power level display from any mounting angle.
• Includes: Ball mount, YS adapter, fiber optic port cover, dome diffuser, warming filter, USB-C PD charger, spare O-rings.
