Combine the compact and easy to use ReefMaster RM-4K with the wide beam of the Sea Dragon 2000F and you have the perfect compact package for exploring reefs, wrecks and deeper dives were lighting will make your images and videos shine with color. The Sea Dragon 2000F has an easy one button design that cycles through three light intensity settings and has a rechargeable battery that lasts an hour at full power (2000 lumens).
The SeaLife RM-4K features brilliant 14mp still images and vivid 4K video in a incredibly small package that’s easy to hold and use alone or with attached lights like the SeaLife Sea Dragon. The ultra-compact removable inner camera and a robust external housing that mounts easily to a light tray. The easy, 4-button control system makes catching the action an effortless process. The ReefMaster offers WiFi sharing ability, so you can wirelessly preview, download and share pictures & videos to a smart phone or tablet with the free ReefMaster app from Google Play Store or Apple App Store.
The easy to hold ergonomic housing was especially designed for use underwater, while the housing is easy to hold and use even with one hand, the tough enclosure also features a unique closing system – a “Pressure Lock” thumb screw that exerts the optimal amount of pressure on the housings O-ring seal. The waterproof housing encases the small inner camera, and also stores a powerful drying agent called “Moisture Muncher” next to the camera that prevents internal fogging caused by heat and humidity trapped inside the housing.
With the expandable memory of the ReefMaster RM-4K, you can use Micro SDHC memory cards up to 128GB, ensuring you have room to shoot & save all of your video content. It also has a time lapse function – shooting at set time intervals and saves as video file or series of still images. For optimal results, especially when shooting 4K video, use Micro SDXC Class UHS Class 3 (U3) or Video Class 30 (V30) memory cards.
Lighting is easy, use the ReefMaster RM-4K with Sea Dragon constant underwater LED photo/video lights (or other LED light sources). There’s no flash or cable to sync to an external strobe. Simply turn your light on and adjust the intensity based on the subject, conditions and distance.
The new Sea Dragon 2000F UW photo-video light delivers 2000 true lumens and a smooth, even 120° wide beam angle. This revolutionary COB LED technology produces an 80 CRI (color rendering index) that mimics natural daylight. Includes Battery and charger with international plug adapters, Flex-Connect Micro tray and grip. Also try the optional 10x close-up or super macro lenses. The sharp 2.0” TFT color LCD display is easy to see in all light conditions and will help keep the lens on your subject.

*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.
