Product Information
The SeaLife Sea Dragon 3000SF Pro Dual Beam is an underwater photo, video, and dive light that switches with one button between a 3000-lumen 120° wide beam and a 1500-lumen 15° narrow spot beam, plus a 180-lumen 88° red LED mode, and it is depth rated to 330 feet (100m).
Who it is for
This light suits divers and underwater photographers and videographers who want one tool for flood lighting, a narrow spotlight or snoot effect, and a red light mode for night dives or working near light-sensitive marine life without losing night vision. The narrow beam's long effective range also helps locate fish hiding in dark areas.
Key details
- Wide beam: 3000-lumen COB LED (BridgeLux V18), 120° on land / 90° underwater, 5000K, 90 CRI
- Narrow beam: 1500-lumen LED (Luminus SST-40-W), 15° on land / 11° underwater, 6000K, 70 CRI
- Red beam: two Luminus SST-10-R LEDs, 180 lumens, 88° on land / 66° underwater
- Battery: removable 7.4V, 3400mAh, 25Wh Li-ion pack; charges in 170 minutes
- Runtime: 60 minutes at full wide-beam power, up to 240 minutes at 25% wide beam or on red
- Depth rated to 330 feet (100m); anodized aluminum head with fiber-reinforced polycarbonate body
- Weight: 15.8 ounces (449 grams) with battery installed; negative buoyancy of -111 grams underwater (light head only)

- Red light mode: Two Luminus SST-10-R red LEDs produce 180 lumens at 88° (66° underwater) for night dives without disturbing night vision.

How long does the battery take to charge?
The included 7.4V, 3400mAh, 25Wh Li-ion battery charges in 170 minutes using the included AC power adapter and international plug adapters.
How deep can the Sea Dragon 3000SF Pro Dual Beam be used?
It is depth rated to 330 feet (100 meters), with an anodized aluminum light head and dual silicone O-rings.
