SeaLife Sea Dragon Mini 1600s Underwater LED Dive Light illuminating a reef

SeaLife Sea Dragon Mini 1600s Underwater LED Dive Light

Compact, rugged, and brilliantly focused—your dependable spot beam for signaling, scouting, and lighting subjects.

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 spot beam from the Sea Dragon Mini 1600s lighting a subject

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

  • High / Medium / Low output
  • Strobe & SOS signaling modes
  • Battery indicator for quick checks
