Product Information
The SeaLife Sea Dragon Fluoro-Dual Beam Photo/Video Light is an underwater video and photo light that switches between a 65° blue fluoro flood beam and a 15° white 800 lumen spot beam, is depth rated to 330ft/100m, and runs on a removable 7.4V, 3400mAh, 25Wh Lithium Ion battery.
Who it is for
This light suits underwater photographers and videographers who want to capture fluorescent night dive subjects as well as standard video and photo footage with one light head. The six CREE XT-E Royal Blue LEDs with an integrated dichroic filter emit light at 450 to 460nm to excite fluorescent colors in marine life, while the single CREE XP-L white LED spot beam handles conventional lighting needs, so divers can switch modes with one button rather than carrying two separate lights.

- Switchable dual beams use six CREE XT-E Royal Blue LEDs with a proprietary dichroic filter at 450 to 460nm for a flood beam and one CREE XP-L LED for a white spot beam.
- Even illumination comes from a 65° fluorescent flood beam and a 15° white spot beam with no hot spots.
- One button control powers the light on and off with a long push and cycles brightness modes with a short push.
- Four brightness levels are available: 100% fluoro flood, 50% fluoro flood, 100% white spot, and 50% white spot.
- Hidden emergency signal mode offers a 1 second blink interval or SOS Morse code, activated by a long push of the power button.

Frequently Asked Questions
What is the run time of the SeaLife Sea Dragon Fluoro-Dual Beam?
The fluoro flood beam runs 1 hour at full power or 2 hours at half power, and the white spot beam runs 2 hours at full power or 4 hours at half power. The removable 25Wh Lithium Ion battery recharges in about 170 minutes.
Does the Sea Dragon Fluoro-Dual Beam work with cameras other than SeaLife?
Yes. It mounts using a standard 1/4-20 tripod screw, which fits SeaLife cameras as well as other underwater camera brands that use the same mount. The light is also Flex-Connect compatible, so it can be added to Flex-Connect trays, grips, Flex Arms, and other accessories.
What filters are included for fluorescent viewing?
The light includes an integrated dichroic filter on the blue LEDs plus two universal yellow barrier filters: one for your dive mask and one for your camera. The camera filter fits lens diameters up to 47mm and blocks residual blue light so you see the fluorescent response from marine life instead.
