The Sea Dragon 2500 (SL671) uses flat panel COB LED technology to closely mimic natural sunlight, bringing out amazing colors in underwater photos and videos. With a Color Rendering Index of 90, the Sea Dragon 2500 solves the issue of blue underwater photos and videos by giving divers the ability to add light down to 200 feet/60 meters with portable sunlight. Includes Flex-Connect Single tray, grip and GoPro® Camera adapter.

An ultra wide beam
The incredibly wide 120-degree beam (90-degrees underwater) of the Sea Dragon 2500 ensures maximum lighting coverage and is ideal for cameras with a wide field of view, like the SeaLife Micro HD, 2.0 or GoPro. With a lab verified lumen output of 2500, the light has a 60 minute burn time at full power – making it incredibly efficient as well as bright.

Easily expand with Flex-Connect
A Flex-Connect Single Tray, Grip and fitted case are included with the light. For those that want to expand an existing set, the light head is also available on its own (Item SL6712). 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!”

*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.
