  • This ready-to-go underwater camera package includes the ultra-compact Sealife Reefmaster RM-4K camera and a wide beam Sea Dragon 2000F light that complements the camera's wide-angle lens to add light and colour back to darker environments. The RM-4K is designed to be easy to use underwater with simple button operation when dexterity can be impaired by gloves.

    Despite being such a small camera the SeaLife RM-4K takes brilliant 14 Megapixel still images and vivid 4K video and is really easy to hold and use alone or with attached lights like the SeaLife Sea Dragon Pro 2000F included in the pack. The ultra-compact removable inner camera and a robust external housing mount easily to the light tray and 4 easy to operate buttons controls the camera and system to make catching the action an effortless process. The RM-4K feature a WiFi sharing ability, so you can wirelessly preview, download and share pictures & videos to a smartphone or tablet with the free ReefMaster app.

    The easy to hold ergonomic housing was specially 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 saving as a 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.

    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 (colour 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 colour 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 a 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.
