Sea Dragon Duo 9000F Set (Discontinued)

RRP $1,349.95

The Sea Dragon 4500F photo-video lights each deliver 4500 lumens in an even 120° wide beam.  Side by side they offer even more complete coverage of any subject at nearly any shooting angle including usage with wide angle dome or fisheye lenses.
SKU: SL692 Category: Product ID: 19948


The dual 4500 lights offer an unmatched 96 CRI (color rendering index) with their proprietary COB LED array that closely simulates natural sunlight (A CRI of 100 would be just like outdoor daylight).  Most other LED lights offer a much lower CRI, missing critical colors necessary produce natural and colorful still images and videos.  The Sea Dragon 4500s, with their unique COB LED, not only offer a high CRI, it also deliver a TLCI (Television Lighting Consistency Index) value of over 97.  With 100 being the highest possible TLCI value, lights producing more than 90 TLCI are acceptable for capturing true, natural colors with television studio cameras – making the Sea Dragon 9000F set the perfect combination for brilliant and colorful underwater video.



The Sea Dragon 9000 dual light set also offers impressive still image results and can be used as a primary source of light.  Should you want to add a strobe, the 4500 lights feature Auto Flash Detect mode, which cancels the light for one second when a strobe is fired.


The Sea Dragon Duo 9000 Set’s brightness can be adjusted manually or automatically with the lights’ built-in photocell light sensor.  The Auto Bright mode automatically adjusts from 450 to 4500 lumens based on proximity to the subject, helping to preserve your eye’s natural night vision and extends battery life. The lights can also be manually adjusted to 100%, 75%, 50% or 25% brightness.


Adjusting and directing your lighting is easy with the Sea Dragon Duo 9000 Set, since it includes a Flex-Connect dual tray, along with two Flex-Connect grips and two Flex-Connect flex arms.   This offers the user many lighting options, and the system is ready for further expansion with other lights, strobe or additional flex arms.

*CRI is a measure of a light source’s ability to show object colors “realistically” or “naturally” compared to daylight, which has a CRI of 100 and represents the maximum value.

The beam angles for the Sea Dragon lights are shown as the true, tested “in-air” (above water) beam angle. Underwater, due to light refraction, the angle tightens to approximately 33% less.

Avoid using this Sea Dragon light above water for prolonged periods of time
The light is designed for underwater use and water is needed to displace heat. The metal light head at full power will reach temperature of about 140F (60C) degrees within a few minutes, which may cause burning if touched. A thermal sensor will automatically dim the light if internal temperatures reaches 150F (65C) degrees. Immediately turn off light if any parts of the light become hot to the touch.
