SeaLife Sea Dragon Lights — Portable Sunlight for Underwater Imaging
Introduced in 2013 alongside the Flex-Connect mounting system, Sea Dragon lights solve underwater photography's oldest problem: water filters out color, starting with red, leaving everything looking flat and blue past a few meters of depth. Sea Dragon's COB LED technology uses a high Color Rendering Index — typically 90 or above — to closely mimic natural sunlight, restoring the colors a strobe-free, constant-light photographer would otherwise lose.
At DiveCatalog.com, we carry the current Sea Dragon lineup as an authorized dealer.
The Sea Dragon Light Range
2000F — Wide Flood for Action Cameras
The 2000F (the "F" stands for Flood) uses a 120° topside beam angle (90° underwater) with three power levels at 100%, 50%, and 25% of its 2000-lumen output. The wide beam is ideal for compact action cameras, ensuring the entire recorded scene is evenly flooded with light rather than producing a hot spot in the center of frame.
2500F — Bright, Natural Color Rendering
The 2500 delivers a lab-verified 2500 lumens with a Color Rendering Index of 90, paired with the same ultra-wide 120° beam (90° underwater) ideal for wide-field-of-view cameras like the SeaLife Micro series or GoPro. A 60-minute burn time at full power balances brightness with practical battery life across a typical dive.
3000F Color Boost — Patent-Pending Color Restoration
The 3000F delivers 3000 lumens in the same smooth 120° wide beam, powering on at 5000K white light, but adds SeaLife's patent-pending Color Boost mode — warming the color temperature to 3900K and replenishing the red wavelengths water filters out first, for a noticeably more balanced and vivid result both to the eye and on camera. A large knurled dial allows stepless brightness adjustment from 300 to 3000 lumens, with a simple push switching between white and Color Boost modes. A red-only stealth mode protects light-sensitive sea creatures during night dives, and emergency signal modes (SOS or steady blink) run 20+ hours on a full charge.
3000SF Pro Dual Beam — Flood and Spot in One Light
The Dual Beam light switches between a wide 3000-lumen, 120° flood beam and a narrow 1500-lumen, 15° spot beam with a single button push — the spot beam useful for creating a focused snoot effect, a stage-spotlight look, or as a primary/secondary dive light for general use. Two 180-lumen, 88° red LEDs round out the mode cycle for night diving without disturbing light-sensitive marine life.
Duo 5000F Set — Dual-Light Power
Pairs two Sea Dragon 2500 light heads on a Flex-Connect Dual Tray with grips for nearly 5000 combined lumens and significantly wider coverage — enough light even for ultra-wide-field-of-view cameras, with the added stability of a dual-grip rig.
Fluoro-Dual Beam — Fluorescence Photography
Developed in partnership with Fire Dive Gear, this light emits a Royal blue beam (450–460nm) through an integrated dichroic filter, precisely tuned to excite fluorescent proteins in coral, fish, and other marine life into a visible light response. Switches between blue fluoro flood and an 800-lumen white spot with a single button. Includes both a mask barrier filter (to block residual blue light from your own vision) and a camera barrier filter (up to 47mm lens diameter) to properly capture the fluorescence effect. Depth rated to 330ft (100m).

Frequently Asked Questions — SeaLife Sea Dragon Lights
What is Color Boost mode?
A patent-pending feature on select Sea Dragon lights that shifts color temperature from 5000K to 3900K, replenishing red wavelengths that water absorbs first — producing warmer, more naturally colorful underwater images and video without a separate color-correction filter.
What is the difference between the 2500F and 3000F?
Both use the same wide 120° beam and high CRI for natural color rendering. The 3000F adds the patent-pending Color Boost mode and a higher 3000-lumen maximum output, along with a more refined dial-based control system.
What is the red-only stealth mode for?
Red light is less visible or disturbing to many light-sensitive marine creatures, making red-only mode useful for night dives where you want to observe behavior without scaring subjects away — a feature shared across several Sea Dragon models.
Can Sea Dragon lights be used as emergency signaling devices?
Yes — select models include SOS and steady-blink emergency signal modes that run 20+ hours at full brightness on a single charge, a useful secondary function beyond photography lighting.
What is needed for fluorescence photography with the Fluoro-Dual Beam?
The light itself, plus the included mask barrier filter (worn over your dive mask) and camera barrier filter (attached to your camera lens, up to 47mm diameter) — both are included with the Fluoro-Dual Beam kit, so no separate filter purchase is needed to get started.
