Product Information
The SeaLife Sea Dragon 2000F is an underwater photo-video light head built around a single COB LED array that produces 2000 lumens at 5000K with an 80 CRI, rated to 330 feet (100 meters) and powered by a removable 25Wh Lithium Ion battery.
Who it is for
The Sea Dragon 2000F is designed for divers using small compact or action cameras who want a flood light that illuminates the full recorded area rather than a narrow spot. Its 120 degree topside beam angle (90 degrees underwater) is built to avoid hot spots when paired with compact or action camera setups.
Key details
- Light source: 1x COB LED array (CREE CXA1816 P4 36V) producing 2000 lumens, maintained throughout the burn time at full power
- Color temperature of 5000K with an 80 Color Rendering Index
- Three brightness levels: 100%, 50%, and 25%, with a hidden emergency signal mode (1 second blink or SOS Morse code) activated by holding the power button for 4 seconds
- Run time of 60 minutes at full power, 120 minutes at half power, and 240 minutes at quarter power; battery charge time is 170 minutes
- Anodized aluminum light head with a fiber-reinforced polycarbonate body, depth tested to 330 feet (100 meters)
- Weighs 13 ounces (370 grams) with battery installed and is negatively buoyant at -94 grams underwater
- Bulb life rated at 35,000 hours; dual silicone O-rings with lubricant
Compatibility and sizing
The light head connects using SeaLife's Flex-Connect system of trays, grips, arms, cold-shoe, ball joint, and Y-S adapters, and mounts to any underwater camera system using standard 1/4-20 tripod mounts or GoPro camera mounts.

- 2000 lumen COB LED array: lab-tested, not theoretical, output from a single CREE CXA1816 P4 36V COB LED.
- One-button control: a single button powers the light on and off and selects brightness.
- Three brightness levels: 100%, 50%, and 25% of the 2000 lumen output.
- Hidden emergency signal mode: 1 second blink interval or SOS Morse code, activated by holding the power button for 4 seconds.
- 60 minute run time: at full power, with 120 minutes at half power and 240 minutes at quarter power.
- Constant brightness: regulated circuitry keeps output steady as the battery depletes.
- 80 CRI: color rendering index that mimics natural daylight at 5000K.
- 120 degree wide beam angle: evenly illuminates the subject with no hot spots (90 degrees underwater).
- Flex-Connect expandability: compatible with trays, grips, arms, cold-shoe, ball joint, and Y-S adapters.
