Strobe Flash Kraken S80 KR-S80

The KR-S80 is Kraken’s mid-range underwater strobe — a fully manual unit built for underwater photographers who want reliable, predictable output without the complexity of TTL. 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.

The 1.0-second recycle to full power is genuinely fast for 80Ws — fast enough for most shooting situations including moving subjects and multi-strobe setups. At ~800 flashes per charge, you’re not going to run out mid-dive. The circular flash tube produces even, wrap-around illumination with soft edges — no hot spots, no hard shadows. The 140 degree+ coverage angle is wide enough to work with most fisheye and wide-angle wet lenses without vignetting.

The built-in 3000-lumen video light (100 degree beam) doubles as a focus light for low ambient conditions, and is independently controlled — useful for video work or as a modelling light to preview your coverage before you fire.

Key Features:

• 80 Ws, Manual Power Control: 6 levels (2 / 5 / 10 / 20 / 40 / 80 Ws). Rotary dial — straightforward to adjust mid-dive.
• Fast Recycle: 1.0 second to full power. Quick enough for most action and wide-angle work.
• ~800 Flashes Per Charge: 2x 21700 batteries (4000mAh each), USB-C rechargeable. Strong battery life for multi-dive days.
• S1 / S2 / Multi 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.
• 3000-Lumen Video Light: 100 degree flood beam, independently controlled with 5 brightness levels. Also works as a focus/modelling light.
• Fiber Optic Port: 7mm hole port + M11 threads. Compatible with standard fiber optic cables.
• 180 degree Rotatable Display: 7-segment LED — readable from any mounting angle.
