Ultra-Compact, High-Intensity Dive Light The Sea Dragon Mini 1600 delivers a powerful 1600-lumen narrow spot beam in an ultra-compact design—ideal for long-range visibility and illuminating sea life from a distance. Its 6° beam angle (4.5° underwater) cuts through darkness for enhanced clarity in crevices or during night dives. All five light modes—full power, half power, quarter power, one-second blink, and SOS signal—are easily accessible with one-handed operation. Long-Lasting Performance Built for extended underwater adventures, the Mini 1600 runs up to 4 hours on quarter power, 2 hours on half power, and 1 hour at full brightness using the included 18650 3500mAh rechargeable battery. A built-in safety pressure release valve in the battery compartment provides added protection. Lightweight and ergonomic, this dive light is the perfect primary or backup companion for any dive.
