The Kraken Hydra 1800+WSR offers 1,800 lumens flood and 1,500 lumens spot in one compact torch, plus red mode for night diving and auto flash-off for strobe shooters. The WSR version includes a wide snoot ring for macro spotlighting. USB-C charging, 100m depth rated.

1800 lumens of flood light. 1500 lumens of spot. Red mode for night diving. Auto flash-off for shooting with strobes. The Hydra 1800+WSR is two useful beams in a compact 205g torch — flood for general diving, spot for navigation and signaling, and a feature set designed for divers who shoot macro with strobes.

The 21700 battery gives you longer runtime than older 18650 cells, and USB-C charging means no cradle to lose — plug in the cable and you’re ready for the next dive. The upgraded 1800-lumen output replaces the previous Hydra 1500 with more brightness in the same form factor.

Key Features

• Dual beam: 1800 lumens flood (110°) + 1500 lumens spot (20°) — wide illumination for diving, tight beam for navigation and signaling
• Auto flash-off: The light detects when your strobe fires and automatically turns off for a fraction of a second, preventing your video light from blowing out your macro shots. Enable or disable based on your preference
• Red mode: Preserves night vision and won’t disturb marine life on night dives. Also works as a focus light for macro photography
• USB-C charging: No cradle, no external charger — charge directly with any USB-C PD cable
• 21700 battery: Higher capacity than 18650 cells, longer runtime between charges
• Single push-button control: Flood ? Spot ? Red, with battery level indicator
• Compact: 205g on land, 105g underwater — won’t weigh you down
• Depth rated to 100m / 330ft

Auto Flash-Off — How It Works
When enabled, the Hydra 1800+WSR detects the flash from your strobe and turns off momentarily, so your video light doesn’t compete with your strobe exposure. This is especially useful for macro shooters who run a constant video light for aiming but also fire a strobe for the actual exposure. No more blown-out highlights from your focus light. The feature can be toggled on or off — use it when you need it, turn it off when you don’t.

Safety Modes
Like every Kraken light, the Hydra 1800+WSR includes three built-in emergency signaling modes accessed by holding the power button — Pulsing Strobe, SOS, and Rapid Blink. On the surface after a dive, these are the modes that get you found.
