Marelux Artemis 6000 lumen underwater video light for underwater photography and video

Marelux Artemis 6000lm Underwater Video Light

Name: Marelux Artemis 6000lm Underwater Video Light
Brand: Marelux

A 6,000-lumen, CRI 95 wide-beam video light built for accurate color, hands-on exposure control, and optional cable-free remote lighting underwater.

Marelux Artemis 6000

The Marelux Artemis 6000 is a high-CRI underwater video light delivering 6,000 lumens through a broad 120° beam, with a stepless manual power dial and support for Marelux's optional encrypted optical remote-control system. It makes the most sense for photographers and videographers who want one light to handle normal on-camera illumination, controlled off-camera lighting, and hybrid still/video workflows.

Underwater, the standout use case is creative lighting where the lights are not always within arm's reach: wreck interiors, caves, reef backlighting, multi-light video sets, and still-photo setups where a continuous target light needs to disappear briefly during the strobe exposure.

Best for: serious underwater video, wide-angle reef work, wreck and cave lighting, hybrid photo/video rigs, and creative off-camera lighting.
Main advantage: 6,000 lumens, CRI 95, 5000K output and a 120° beam give you a useful combination of brightness, coverage, and color accuracy.
Compatibility: this is fundamentally camera-independent lighting; your main compatibility questions are mounting, battery configuration, and whether you want the optional Marelux remote or fiber-optic control functions.
Major differentiator: optional encrypted optical remote power control allows lights to be positioned away from the housing without a traditional control cable.
Hybrid-photo advantage: Smart Target Light mode can switch the continuous light off for 0.2 seconds when it detects the camera's optical flash signal.
Tradeoff: full-power runtime is 50 minutes with two 21700 cells, the remote controller is a separate component, and the battery chamber uses plastic rather than an all-aluminum construction.

Remote Lighting That Actually Changes How You Can Position a Light

Fully Wireless Remote Control: The first completely wireless, remote-controlled underwater video light. Utilizing the Artemis 4500RMT 2.0, users can adjust power levels from 12 to 15 meters away underwater via built-in blue light emitters. Remote adjustment is crucial for creative lighting layouts, cave diving, and wreck diving. By eliminating cables, users can position multiple lights far from the camera housing, opening up endless possibilities for underwater photography.

Interference-Free Encrypted Signal: The remote control signal uses an internationally patented, encrypted optical frequency. It cannot be disrupted by strong sunlight, a dive buddy's strobes, or competing video lights. Only the dedicated encrypted blue light can adjust the brightness (from 0% to full power), ensuring absolute reliability in any environment.

Self-Synchronizing Encrypted Signals: Each of the 5 remote power levels emits a unique, independently encrypted signal. Even if a video light misses a signal change due to an obstruction, it will instantly synchronize with the very next signal it receives. This ensures that all multi-light setups stay perfectly balanced and synced at the exact same power level.

CRI 95, 5000K Light With a Wide 120° Beam

Lumens tell you how much light is being produced; they do not tell you whether a red sponge, orange anthias, or diver's skin tone will reproduce well on camera. The Artemis uses a COB LED rated at CRI 95 and 5000K, which is the specification we pay attention to when accurate color matters as much as raw brightness.

120° coverage is suited to wide underwater scenes and close working distances
CRI 95 is a strong specification for color-sensitive photo and video work
5000K output provides a neutral daylight-oriented starting point for white balance
Stepless analog control lets you trim exposure without cycling through fixed brightness increments

Built for Divers Who Switch Between Stills and Video

In Smart Target Light mode, an optical flash signal sent from the housing through a standard fiber-optic cable tells the Artemis to switch off for 0.2 seconds, then come back on. That is useful when you want continuous light for composing and focusing but do not want it contributing unwanted exposure while a Marelux strobe or another compatible strobe lights the still image.

Continuous light remains available for focusing and subject acquisition
Temporary light shutoff helps keep the video light out of a strobe exposure
Two ball-mount positions allow the control dial orientation to suit different arm positions
User-replaceable 18650/21700 cell options reduce dependence on a single proprietary battery pack

Ultra-Compact Sensor Dome: The remote receiver's sensor dome is minimized, ruggedized, and safely integrated into the housing.
Fiber Optic Remote Capability: Marelux also offers an optional fiber optic remote control connection. Using a specially designed fiber optic cable with custom caps on both ends, you can link the receiver port directly to the emitting dome. This allows the Artemis 4500RMT 2.0 to control the light even when it is hidden behind rocks or reefs where the wireless signal would be blocked.
Streamlined 5-Stop Remote Adjustments: The remote control features exactly 5 power levels. When using a remote, divers need to make adjustments instantly. The most critical actions are turning the light on/off and switching to key power levels in a split second to catch fast-moving marine life. A shorter power cycle ensures lightning-fast operation.
Studio-Quality COB LED: Features a premium COB LED with a CRI of 95 and a color temperature of 5000K, accurately restoring the true, vibrant colors of your underwater subjects.
Smart Target Light (Flash Mode): This mode allows the Artemis to act as a focus/target light for still photography. When your camera shutter triggers, the flash signal travels via a standard fiber optic cable from the camera housing to the light's flash sensor port. Upon detecting the signal, the video light instantly shuts off for 0.2 seconds before automatically turning back on. This ensures the powerful light does not ruin your exposure or appear in the final photograph.
Stepless, Seamless Power Dial: The video light is equipped with a rugged, analog dial for seamless, stepless brightness adjustment. Unlike competitors that limit you to fixed increments, this allows you to fine-tune the illumination to the exact level required for your shot.
Dual Ball Mount Positions: To accommodate different shooting preferences, the light features two ball mount positions. If you mount the light directly on top of the housing or handles, you can position the dial facing up for easy access. If you hang the light from strobe arms, you can flip the orientation so the dial faces downward for effortless adjustment.
Innovative Hybrid Construction: The first high-power video light to feature a half-plastic body design. This significantly reduces manufacturing costs, allowing us to deliver a high-performance video light to the market at a fair and highly competitive price.
User-Replaceable Battery System: The first high-power video light that allows users to change batteries freely. Proprietary battery packs are a major pain point. Imagine diving on a remote island and your custom battery pack fails—you would have to wait weeks for a replacement shipment while standard batteries are everywhere around you. Built-in battery circuits add a risk of failure. We believe less is more: keeping your power supply simple, reliable, and accessible.
Robust and Simplified Locking Mechanism: The battery chamber utilizes a straightforward, highly reliable locking system. For frequently used mechanisms, simplicity outperforms complexity. A rugged 6mm screw is the most dependable way to prevent mechanical failure underwater

Marelux Artemis 6000 Frequently Asked Questions

Will the Marelux Artemis 6000 work with my underwater housing?

Usually, yes. The Artemis 6000 is a camera-independent continuous light, so the main requirement is a compatible tray, arm, clamp and mounting system rather than a specific camera body; contact Bluewater Photo if you want us to confirm your exact configuration.

Do I need the Artemis 4500RMT 2.0 to use the Artemis 6000?

No. You can control brightness directly with the Artemis 6000's stepless dial; the Artemis 4500RMT 2.0 is optional and is used when you want remote optical power control.

Will wireless remote control work if the light is behind a rock or inside a wreck?

The remote system uses an optical blue-light signal, so a solid obstruction can block the wireless path. Marelux provides an optional fiber-optic remote connection for situations where the light needs to be hidden from direct line-of-sight.

Can I use the Artemis 6000 as a focus light with underwater strobes?

Yes, using Smart Target Light mode and the appropriate fiber-optic connection. When the light detects the camera's optical flash signal, it switches off for 0.2 seconds before turning back on, helping keep the continuous light from affecting the strobe exposure.

What batteries does the Marelux Artemis 6000 use?

Marelux specifies configurations using 2×21700, 4×18650 or 4×21700 cells with continuous discharge current greater than 10A. Confirm the correct battery holder, approved cells, charger and included accessories before ordering.

How long does the Artemis 6000 run at full power?

Marelux specifies approximately 50 minutes at maximum output with two 21700 batteries and approximately two hours with four 21700 batteries.

Is one 6,000-lumen light enough for wide-angle underwater video?

One light can work well at close and moderate distances, especially with a 120° beam. For very wide scenes, two lights generally give you better coverage, more even illumination, and greater control over shadows and backscatter.

How should I maintain the Artemis 6000 after diving?

Rinse the exterior thoroughly in fresh water after saltwater dives, dry the light before opening the battery compartment, and inspect sealing surfaces and O-rings as directed by Marelux. Do not open the battery chamber while the light is wet or where water, sand, or salt can contaminate the sealing area.
