Reveal rich fluorescent colors
In partnership with Fire Dive Gear, we have created the Sea Dragon Fluoro-Dual Beam, that emits a powerful blue light beam and adds an integrated dichroic filter creating the optimal light wavelength to “excite” underwater life. Two switchable beams transform the versatile light from a blue fluoro 65° flood light to a white 800 lumen 15° concentrated beam with a push of a button. A rechargeable Lithium Ion 7.4V, 3400 mAh, 25Wh battery delivers power for a full 60 minutes at 100% fluoro emission. With its single button operation, the light can quickly adjust between four brightness modes: 100% fluoro flood, 50% fluoro flood, 100% white spot, and 50% white spot. Depth rated down to 330ft/100m.

Vibrant and rich fluoro-colors
The Sea Dragon Fluoro-Dual Beam’s Royal blue LED’s, with their filter, emit blue light in the range of 450-460nm; the wavelength to “excite” the fish, plants or organisms into making a light filled energy response. The finely tuned and proprietary dichroic filter pinpoints the exact light wavelength to get the highest energy response from the underwater subjects.

Enhance your underwater fluoro-viewing
Two universal, barrier filters are included to improve your experience in underwater fluorescent viewing and imaging. The mask filter fits over the dive mask to filter out the residual presence of blue light emitted by the light (it’s the response from the sea creature you want to see, not the blue light). The second filter attaches to any underwater camera with a lens diameter up to 47mm.

Easily expand with Flex-Connect
A Flex-Connect Single Tray, Grip and fitted case are included with the light. Flex-Connect allows you to quickly and easily transform your camera set from compact to full-featured in just seconds by adding grips, Flex Arms, trays and more with just a “click!”


Switchable dual beams features six CREE XT-E Royal Blue LED’s with proprietary dichroic filter (light wavelength 450-460nm) flood beam and one CREE XP-L LED white spot beam.
65° fluorescent wide angle beam and 15° white spot beam angle evenly illuminates the subject with no hot spots.
One button control for easy operation – one button to power light on/off and select brightness.
Four brightness levels: 100% fluoro flood, 50% fluoro flood,100% white spot, and 50% white spot.
Hidden emergency signal mode: 1 second blink interval and SOS Morse code.
60 minute run time at full power and constant brightness.
Depth rated to 330 feet/100 meters.
Easy to expand with Flex-Connect™ trays, grips and Flex Arms, handle, Y-S, ball joint, cold shoe and other accessories.
Quick-release button to detach light and aim in crevices and hard to reach areas.
Includes integrated dichroic filter and two universal barrier filters for your dive mask and camera for optimal fluoro viewing and photography.
Corrosion-proof metal light head for heat dispersion and durability.
Removable 25W Li-Ion battery w/ charger and international plug adapters included.
Waterproof battery compartment – even if the O-ring seal fails, the battery compartment is isolated so water cannot reach the internal electronics.
Universal mounting screw fits SeaLife and other brands of underwater cameras w/ standard ¼-20 tripod mount.
Protective circuitry – The light and battery feature integrated protective circuits that cuts power in the unlikely event the light overheats or short circuits.
Safety pressure release valve – one-way waterproof valve releases battery compartment pressure in the unlikely event of battery malfunction.

SeaLife Sea Dragon Fluoro vs. Harmful UV lights

For BEST results and SAFETY reasons, the Sea Dragon Fluoro-Dual Beam uses Cree Royal Blue LED’s combined with a proprietary dichroic filter.  SeaLife NEVER has and never will use Ultraviolet (UV) LED’s. 

Some companies are selling underwater UV lights claiming the results are better than blue LED’s, and that there is no need for yellow barrier filter over your mask and/or camera. The truth is that UV lights pose a serious safety hazard to the eyes of humans and sea creatures. UV light is invisible, so you don’t realize that your eye is being bombarded with UV rays. It is a proven fact that extended exposure to UV light has been linked to eye damage, including cataracts, macular degeneration, pingueculae, pterygia and photokeratitis that can cause temporary vision loss. 

The Sea Dragon Fluoro-Dual beam’s Blue LED’s, combined with our exclusive dichroic filter, emits a powerful blue light creating the optimal wavelength to excite underwater organisms. To see the fluorescence effect best, two yellow barrier filters are included – one for your mask and another for your camera. The primary purpose of the yellow filters are to absorb the visible excess blue light, so you only see is the fluorescence effect. 

Underwater testing shows that more sea creatures fluoresce when exposed to the Sea Dragon Fluoro-Dual Beam when compared to UV lights.
