The SeaLife Sea Dragon Mini 1600s is a powerful, pocket-size spot light designed for divers and underwater image-makers who need clean, concentrated illumination. It pairs perfectly with action cams and compact rigs, or as a precise focusing/indicator light alongside larger Sealife lights.
Whether you’re exploring wreck interiors or picking out macro details, the Sealife Sea Dragon Mini 1600s delivers a tight, even beam with intuitive controls. It’s the ideal secondary Sealife flashlight for directing viewer attention and cutting through backscatter.
- 1600-lumen spot beam (≈15° on land / ≈11° underwater) for reach and contrast
- Multiple power levels + strobe/SOS; one-hand, glove-friendly switch
- Long-run 21700 Li-ion battery option with built-in USB charging
- 100 m / 330 ft depth rating; anodized aluminum body with double O-ring seal
- Compact: great as a focus, pointer, or backup primary light

Tight, Clean Spot for Reach
The 1600s concentrates light into a narrow, even spot that cuts through particulate and reaches distant subjects. It’s excellent for macro focusing, signaling a buddy, and guiding a viewer’s eye in video scenes.
- Approx. 15° spot on land / ~11° underwater
- High center intensity with smooth fall-off
- Reduces backscatter in murky conditions

Simple, Glove-Friendly Controls
A single, tactile switch cycles power levels and emergency modes, so you can operate the light without breaking trim. Status LEDs indicate battery level at a glance before and after the dive.
- High / Medium / Low output
- Strobe & SOS signaling modes
- Battery indicator for quick checks

All-Day Power with 21700 Li-ion
Choose the high-capacity 21700 battery (with USB charging) for longer bottom times or run 18650 cells with an adapter. Double O-rings and a secure tailcap keep your power source protected to 100 m.
- Up to ~90 min on High (typical)
- Efficient thermal management
- USB-rechargeable battery options
