Kraken Sports KR-S40 Compact Strobe

Description

Elevate your underwater photography with the Kraken Sports KR-S40, a compact yet powerful strobe designed for macro enthusiasts seeking exceptional lighting in a portable form. Whether you’re capturing intricate reef details or vibrant marine life, the KR-S40 delivers precise illumination to enhance your shots.

The KR-S40 is Kraken Sports' most compact strobe. This macro powerhouse features 40Ws in a 530g package that won’t throw off your buoyancy or dominate your rig. It uses a straight flash tube rather than a circular tube, which keeps the size down and is well-suited to macro work where close-subject distances mean even a narrow coverage angle lights the scene effectively. Weather you’re shooting nudis, frogfish, snooting, or fish portraits, the KR-S40 is the right tool.

Like Kraken's bigger strobe offerings, the KR-S40 is Manual-only (no TTL).

Key Features:

• 40 Ws, Manual Only: 5 power levels (2 / 5 / 10 / 20 / 40 Ws). No TTL — predictable, repeatable exposure every shot.
• Fast Recycle: 1.2 seconds to full power — fast enough for active subjects and multi-exposure sequences.
• Compact and Lightweight: 530g on land, 200g underwater. Designed to keep your rig balanced without overpowering a compact camera setup.
• Straight Flash Tube: Keeps the size down — the right choice for macro work where you’re shooting close subjects and wide coverage matters less than compact form factor.
• 60°+ Coverage Angle: Well suited to macro and mid-range subjects. Pair two for wide-angle coverage if needed.
• S1 / S2 / Multi Optical Slave: Syncs optically with your camera’s built-in flash or a master strobe. No TTL.
• 300-Lumen Spot Focus Light: 15° beam, 2 levels. Useful for precise focus on small subjects in low ambient light.
• Single 21700 Battery: 4000mAh, USB-C rechargeable. ~500 flashes at full power.
• Available in Pink, Seafoam, and Silver — colour options to match your housing or rig.
