Kraken KR-S80 Strobe

Experienced underwater photographers shoot manual. TTL might sound convenient, but manual gives you predictable, repeatable results — the same exposure every shot, regardless of what's in the frame. The KR-S80 delivers 80Ws of controllable power at a price well below comparable strobes with “smart” modes you won't use once you know what you're doing.

80 watt-seconds. 1-second recycle. ~800 flashes per charge.

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. 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 won't run out mid-dive. The circular flash tube produces even, wrap-around illumination with soft edges, and the built-in 3000-lumen video light doubles as an independently controlled focus/modelling light.
