In the world of underwater photography, light is more than just a technical necessity. It is the soul of every image, the silent composer behind each frame that breathes life into ocean scenes. For serious shooters, the moment inevitably arrives when lighting transcends its functional purpose and becomes an essential language of expression. This is where the Marelux Apollo III emerges not just as a lighting device but as a revolutionary tool that changes how we capture the underwater world.
For years, strobes have balanced power, practicality, and ergonomics with varying success. Some have favored portability over performance, while others delivered brute force but lacked finesse. The Apollo III disrupts this status quo by combining brute power with exceptional design, enabling photographers to create with precision, freedom, and confidence. It is not merely a successor to existing models; it’s a bold reimagining of what underwater lighting should be.
Central to its groundbreaking appeal is the Apollo III’s formidable guide number of 44. This rating is not simply a figure for spec sheets. It delivers an intensity that underwater photographers will immediately notice when shooting in challenging environments. When paired with advanced mirrorless systems like the Nikon Z8, this strobe effortlessly carves through ambient light, even in bright, shallow tropical waters. Its sheer output allows for image clarity and vibrance that surpasses previous generations, preserving natural tones and textures in even the most complex lighting scenarios.
But raw power alone isn’t enough to earn its place at the top. The Apollo III owes much of its transformative capability to its internal battery system. By adopting 18650H lithium-ion cells, Marelux has moved decisively away from legacy AA-powered models, opening the door to both increased energy density and drastically improved cycle performance. The result is a strobe that recycles at a blistering 0.6 seconds at full output. For action photographers, this responsiveness is invaluable. Whether tracking sea lions darting through kelp or capturing the fleeting breach of a whale, the Apollo III matches a shooter’s reflexes, frame by frame.
This speed and consistency unlock a new level of creative freedom. The ability to fire rapid full-power bursts makes it possible to document sequences that might otherwise be lost to delay. Even at reduced power levels, the strobe keeps pace with high-speed burst shooting, making it ideal for capturing fast-moving marine life. It is the difference between capturing a moment and watching it slip away.
Yet power and speed are only part of the story. What truly separates a professional strobe from the rest is the quality of its light. The Apollo III incorporates a triple flash tube in a triangular configuration that evenly disperses light across its native 110-degree beam. This design eliminates hot spots and ensures smooth falloff, delivering a natural and flattering illumination that macro and wide-angle photographers will appreciate. When the included dome diffuser is attached, the beam expands to 140 degrees without sacrificing color consistency or brightness, providing seamless coverage for expansive reef scenes or large subjects.
Color temperature is equally critical, especially when accuracy is paramount. The Apollo III delivers a native temperature of 6200K, which brings a subtle coolness to images that enhances detail and sharpness. When softened with the dome diffuser, the color warms to a balanced 5500K, mimicking natural daylight and offering more tonal flexibility in post-production. This range lets photographers choose the mood and character of their images at the time of capture, not just in editing.
A Field-Tested Performer With Endurance and Elegance
To truly evaluate a strobe’s worth, real-world use under demanding conditions is essential. On our field expedition to the spectacular reefs and walls of Bohol, Philippines, the Apollo III was put through its paces across eight dives over two full days. Paired with a Nikon Z8 in a Marelux housing and mounted with dual Apollo III units, the setup performed with a consistency and ease that made it feel like an extension of vision rather than a tool.
Remarkably, a single charge of the 18650H batteries lasted the entirety of the trip. This level of efficiency changes expectations for strobe usage during liveaboard trips or back-to-back dives in remote areas. Gone are the days of juggling spare AA batteries between dives or dealing with frustrating power limitations. The Apollo III was ready for every frame, every dive, every scenario.
Despite the high-capacity battery and sturdy build, Marelux has managed to maintain a manageable underwater weight. With the neoprene cover, it clocks in at just 115 grams in water, maintaining excellent balance and neutral buoyancy when paired with float arms. On the surface, the strobe is slightly heavier at 960 grams, but this mass is offset by the robust durability and the extended shooting time it provides. Constructed from anodized aluminum, the body is built to withstand rough handling and depth pressures down to 100 meters without compromise.
Durability aside, what impresses most is the thoughtful design of the Apollo III’s user interface. The control layout is both intuitive and tactile, with generously sized knobs that remain easy to operate even while wearing thick gloves. Each dial has a purposeful click and resistance that allows for precise adjustment, whether you’re dialing down for a subtle fill or cranking up for a high-impact burst.
Strobe mode versatility is another area where the Apollo III excels. The inclusion of multiple modes, including TTL, RC TTL, MTL, and high-speed sync, means photographers can tailor the lighting strategy to the subject and situation. Manual mode offers an extensive power range that can be finely adjusted, giving shooters full control over the light output. For those who value absolute control over their exposures, this flexibility is not just a feature but a necessity.
A standout innovation is Marelux’s Lumilink 2.0 wireless optical trigger system. Designed to work through water using a blue light signal transmitted from inside the camera housing, Lumilink allows divers to ditch the bulky and sometimes unreliable sync cords of the past. Though TTL support is somewhat limited in wireless mode, the simplicity and creative freedom of wireless operation far outweigh the tradeoff. The result is a clean, streamlined rig that encourages experimentation with new angles and lighting positions that sync cords simply wouldn’t allow.
Lighting That Inspires: A Creative Revolution Underwater
Great lighting transforms not just images, but the creative process itself. With the Apollo III, every frame becomes a canvas illuminated with intent. During dives in Anda’s vibrant coral slopes, we found ourselves capturing scenes with stunning fidelity using only half or even one-quarter of the strobe’s power. This not only extended battery life but enabled us to fire off sequences at rapid intervals, matching the Nikon Z8’s continuous shooting without missing a beat.
This kind of performance is especially impactful for photographers working with unpredictable subjects. From darting mandarinfish and cryptic nudibranchs to fast-moving reef sharks and feeding manta rays, the Apollo III delivers on the promise of never missing the moment. Its ability to consistently light subjects with precision and richness instills a level of trust that few other strobes can match. That trust becomes essential when the light fades, the current pulls, or the subject suddenly changes course.
Beyond technical excellence, the Apollo III inspires new ways of seeing the underwater world. It invites experimentation, pushing photographers to explore difficult lighting conditions and unconventional compositions. Whether shooting into the sun to create dramatic silhouette shots or capturing minute details on the ocean floor, the strobe’s uniform output and rapid recycling allow the creative process to remain uninterrupted.
It also redefines what is possible in terms of storytelling. Marine ecosystems are dynamic, colorful, and often fleeting in their beauty. The Apollo III’s ability to render that world with clarity and emotional impact elevates not just the quality of individual images but the potential for powerful narrative sequences. This kind of gear becomes more than just a piece of equipment; it becomes a collaborative partner in the creative journey.
Ultimately, the Marelux Apollo III stands apart not because it checks all the boxes, but because it challenges the very idea of what a strobe should be. It doesn’t ask photographers to choose between power, speed, or control. It offers all three in a cohesive, beautifully executed package that feels tailored for the modern underwater storyteller.
Mastering Light Beneath the Surface: The Apollo III’s Approach to Underwater Illumination
The ocean is more than just a backdrop for underwater imaging. It is an ever-changing environment that challenges the very physics of light. Beneath the surface, illumination behaves unpredictably. It refracts, bends, diffuses, and scatters with every shift in current or swirl of particulate. Light under the waterline is unruly and complex, making the job of the underwater photographer far more intricate than simply triggering a flash. It requires a tool that doesn't just deliver brightness but also understands and adapts to the fluid nature of aquatic optics.
Enter the Marelux Apollo III. This is not a strobe that merely emits light; it is a precision instrument designed to shape light with intention and control. Rather than flooding a scene indiscriminately, the Apollo III creates an atmosphere through light-enhancing depth, contrast, mood, and realism in a way that transforms underwater scenes from documentation to visual storytelling.
One of the defining traits of the Apollo III is its uniquely engineered beam quality. Traditional strobes often struggle with uneven light distribution, producing problematic hot spots in the center or inconsistent peripheral coverage. The Apollo III overcomes these long-standing issues through an innovative triple flash tube design. The tubes are arranged in a precise triangular geometry, forming a symmetrical light field that results in smooth, even diffusion across the entire beam. This uniformity is not merely a technical upgrade, is a creative game-changer. Photographers can now compose shots with the confidence that their lighting will remain consistent from center to edge, no matter how they frame their subject.
This engineering feat gives photographers the ability to fine-tune their lighting approach based on environmental needs. The default beam angle of 110 degrees without a diffuser offers a tighter, more dramatic spread of light. This is especially advantageous in reef caves, wreck interiors, or shaded coral structures, where emphasizing light falloff and shadows can add visual drama and depth. For subjects requiring broader, more even illuminations as expansive reefscapes, schooling fish, or models, the optional dome diffuser expands the beam angle to 140 degrees. This wider coverage blankets the subject in a soft, flattering light, ensuring a natural transition from highlights to shadows without harsh lines or overexposure.
What makes this transition between hard and soft lighting particularly useful is how seamless and intuitive it is. You’re not forced to carry multiple lighting modifiers or fumble with settings during a dive. With a simple change of diffuser, the character of the light shifts to suit your environment, allowing for versatility across a single dive. This is especially important when moving between open water and more intimate macro habitats within the same dive session.
Color Temperature and Tonal Precision in the Marine World
The subtleties of color temperature are often underestimated in underwater strobe design. Water absorbs and alters the color spectrum rapidly, with reds disappearing just meters below the surface and blues dominating the visual palette. Accurate color temperature allows the photographer to counteract these natural losses, restoring a sense of realism and tonal balance that brings marine life vividly to life.
The Apollo III is built with an awareness of this chromatic complexity. Without its diffuser, it produces a slightly cool light at 6200K, which enhances clarity and contrast in water-rich compositions. This setting accentuates blues and greens, giving images an edge that cuts through haze and turbidity. Add the diffuser, and the temperature shifts down to 5500 K, much closer to natural daylight. This warmer light tone is particularly effective for capturing skin tones, sandy bottoms, or coral structures with red and orange hues. This flexibility in white balance helps simplify post-processing, providing RAW files that are easier to color correct while maintaining a natural, pleasing aesthetic.
On dives in diverse conditionsfrom the vivid coral gardens of Raja Ampat to the plankton-laced waters of the Pacific Northwest observed how these shifts in temperature could completely alter the emotional impact of an image. In editorial and documentary storytelling, this control over warmth and tone is crucial. It enables photographers to match the mood of their narrative with appropriate lighting, whether they are depicting the clinical detail of a scientific subject or the poetic stillness of a wide reef vista.
In practice, we explored overhangs adorned with feather stars and soft corals, where ambient light was scarce. Using the Apollo III at its native beam without a diffuser, we were able to illuminate small regions within the shadow, carving out pools of exposure that lent a three-dimensional quality to the scene. The hard light rendered texture and form with stunning clarity, drawing attention to fine details without washing out contrast. In other situations, such as capturing reflective species like barracuda or batfish, the addition of the diffuser softened specular reflections, giving the image a painterly quality that still preserved natural detail.
A clean beam without central hot spots offers another significant advantagecreative freedom in strobe placement. Photographers are no longer limited to the traditional 45-degree strobe angle. The Apollo III maintains consistent light output even at extreme or experimental angles, such as cross-lighting from behind or from directly above. The absence of a dominant center hotspot means even sidelit compositions remain balanced, allowing for lighting approaches that emphasize texture, silhouette, and mood without technical compromise.
Real-World Versatility: From Muck Diving to High-Action Scenes
Beyond beam shape and color tone, the Apollo III shines in real-world usability. It performs exceptionally well in environments that typically challenge artificial lightingsuch as muck dives in silty terrain or high-action scenes with fast-moving subjects. In places like Lembeh or Dauin, where suspended sediment can ruin a shot with backscatter, the tight native beam of the Apollo III provides the isolation necessary to illuminate your subject cleanly. There’s no need for snoots or cumbersome beam restrictors. The default beam shape minimizes foreground wash, enabling crisp shots of small subjects like hairy shrimp, blue-ringed octopus, or frogfish without disturbing the visual integrity of the scene.
Another often overlooked aspect of beam character is how light transitions at the edge. Where many strobes exhibit abrupt falloff or overly soft transitions that flatten the scene, the Apollo III introduces a natural, gradual edge roll-off. This subtlety mimics how light behaves in the terrestrial world, adding realism and depth to the background. Wide-angle images benefit especially from this feature, as the ambient lighting appears integrated and believable rather than artificially flashed. In underwater environments where authenticity is key, such nuanced lighting behavior helps elevate a photo from good to unforgettable.
The Apollo III also impresses with its consistent performance across varying power levels. During midday dives in shallow water, we tested the strobe at reduced outputsspecifically 1/2 and 1/4 powerto prevent overexposure in bright conditions. Even at these lower intensities, the quality of the light remained intact. There was no discernible drop in color fidelity, beam uniformity, or coverage. This is a significant achievement that speaks to the advanced internal electronics and the efficiency of the triple tube configuration. It means that no matter your settings, the strobe behaves predictably and professionally, reducing the need for constant adjustments and helping you stay focused on the shot.
Environmental unpredictability is part of the underwater experience. Plankton blooms, fluctuating salinity, cloud cover, and surge can all impact the clarity and behavior of light. Many strobes crumble under these conditions, producing inconsistent beams or revealing design flaws. Yet the Apollo III remains steady, delivering powerful and precise lighting regardless of water conditions. Whether you are illuminating the underbelly of a turtle cruising overhead or capturing the delicate dance of mating mandarinfish during twilight hours, this strobe interprets and delivers light as intended, rather than leaving it to chance.
Ultimately, lighting underwater is about far more than sheer brightness. It is about control, modulation, color, beam shape, falloff, and above all, expression. The Marelux Apollo III is not just a toolit is an extension of the photographer’s creative intent. It provides a level of refinement and reliability that turns difficult environments into creative playgrounds. It lets photographers sculpt light instead of simply surviving it.

The secure seal and clear locking mechanism ensure that even mid-dive battery changes are quick, reliable, and safe from water intrusion.
Speed Meets Consistency: Blazing Recycle Times Without Sacrifice
The Apollo III isn’t just about how long it can run, but also how fast it recovers. In dynamic underwater environments where action unfolds unpredictably, a strobe must not only fire reliably but be ready to do so again within fractions of a second. With a recycle time of just 0.6 seconds at full power, the Apollo III delivers professional-grade responsiveness that is virtually unmatched in its category.
This is not theoretical speed touted in marketing brochures, only achievable at lower settings. This is true full-power cyclingrelentless and repeatable. This level of speed unlocks creative opportunities that many photographers have previously avoided due to equipment limitations. Whether capturing the intricate, synchronized movements of schooling fish or the lightning-fast propulsion of a squid launching from the reef, the Apollo III remains synced with your vision.
Where traditional strobes begin to falter after just a few bursts, slowing their cycle time drastically and compromising the exposure of subsequent frames, the Apollo III maintains composure. During real-world testing with fast-shooting mirrorless cameras, users achieved consistent five to seven-frame bursts at near-maximum output without a noticeable drop in intensity or coverage.
This is largely thanks to Marelux’s internal engineering. Advanced circuitry manages power delivery with impressive precision while actively distributing heat buildup through an intelligent thermal management system. The result is a strobe that not only shoots fast but does so sustainably. Even during long macro sessions or wide-angle sequences requiring dozens of successive high-output flashes, the strobe did not trigger thermal cutback or show signs of output fade.
Heat is one of the main culprits behind power inconsistency in underwater strobes. In warm tropical waters or when used repeatedly during dive safaris, heat buildup can easily cripple lesser strobes. With the Apollo III, those concerns are virtually eliminated. Its internal cooling design and thermal dissipation elements work silently and effectively in the background, keeping the strobe performing consistently across dives and conditions.
This reliability at high speed opens up an entirely new dimension of burst photography underwater. Whether documenting the swirling courtship of cuttlefish in shallow reefs or the intricate strike behavior of predatory fish, photographers are now able to chase the moment frame by frame with confidence that their lighting will be accurate and powerful every time.

Intuitive Engineering Meets Underwater Performance
When you're submerged in an unfamiliar world, surrounded by shifting light, dancing currents, and fleeting marine life, your gear should never be something you wrestle with. In underwater photography, power alone doesn't make a strobe exceptional. The real triumph lies in seamless operation, where the tool becomes a natural extension of the diver. The Marelux Apollo III understands this intimately, translating years of underwater lighting evolution into an intuitive, tactile, and high-performing strobe system.
From the first touch, the Apollo III exudes a sense of purpose-built design. Everything about it, from the way it sits in your hand to how it responds to subtle adjustments, speaks to a refined understanding of the diver’s needs. The control knobs are a standout feature, large enough for confident manipulation even while wearing thick gloves, textured to prevent slips, and perfectly spaced for fingertip control. There's a balance here that feels intentional. Turning a knob delivers enough resistance to reassure you it won’t budge on its own, but never feels so tight that you have to wrestle with it underwater. It's an ergonomic achievement that enhances confidence and control during the most delicate or dynamic moments of a dive.
Unlike other systems that seem to be designed around theoretical use, the Apollo III’s user interface reflects real-world diving insight. Every button press and dial turn feels deliberate. The strobe does not demand your attention but instead responds effortlessly, giving you space to focus on your subject and composition. Whether you’re a novice seeking reliability or a seasoned photographer fine-tuning creative setups, the learning curve here is minimal. The Marelux team clearly prioritized simplicity without sacrificing capability.
This attention to design extends to visibility as well. The strobe’s anodized aluminum shell is both rugged and aesthetically pleasing. Available in colors like deep burgundy, Yale blue, olive, and silver, it adds a layer of personalization that doesn’t compromise durability. The finish resists corrosion and scratches, and the strobe’s included neoprene cover protects its form while also reducing its in-water weight, helping it feel light and maneuverable a key factor on longer dives or during macro sessions where buoyancy precision matters.
Creative Modes That Expand Your Vision
What truly sets the Apollo III apart is the versatility and sophistication of its strobe modes. Unlike many lighting systems that lock you into one style or workflow, this strobe adapts effortlessly to your goals and shooting conditions. Its various flash modes cater to both instinctive shooting and precision lighting setups, helping underwater creators achieve consistent results in constantly changing environments.
TTL mode provides familiar auto-exposure assistance, letting your camera determine the proper flash intensity. It’s ideal for fast-moving action where you don’t have the luxury of dialing in manual settings. Whether photographing darting reef fish or a diver silhouetted against the surface, TTL ensures reliable illumination without hesitation. For Olympus users, RC TTL mode brings another level of optimization. It works seamlessly with the brand’s system to deliver more nuanced exposures, especially beneficial in macro scenarios where minute differences in lighting make or break a shot.
When creative control is paramount, the Apollo III’s manual mode delivers a robust platform. You can fine-tune output with precision, adjusting flash power from subtle glows to full bursts of light. The adjustment dial is marked clearly and clicks securely into place with each increment, allowing easy changes mid-dive, even in low visibility or under time pressure. This level of control gives shooters the ability to sculpt light intentionally, whether for vibrant coral close-ups or backlit pelagic encounters.
Advanced features like HSS (High-Speed Sync) and MTL (Multi Flash) modes expand artistic possibilities even further. HSS allows you to synchronize the strobe with shutter speeds beyond conventional limits. This becomes particularly useful in sun-drenched shallows where ambient light competes with your artificial lighting. By using faster shutter speeds, you can darken backgrounds while still perfectly exposing your foreground subject, creating a striking contrast that enhances mood and depth.
MTL mode opens the door to experimental photography. When used with slow shutter speeds, it produces stroboscopic effects, freezing multiple phases of movement in a single frame. This mode lends itself to unique compositions such as tracking the motion of swimming fish, documenting behavioral patterns, or capturing an otherworldly sense of underwater flow. It invites photographers to push creative boundaries and tell stories through layers of time.
The Apollo III also simplifies the physical connection between camera and strobe with its Lumilink 2.0 system. This optical transmission technology eliminates the need for traditional sync cords. Instead, it sends a blue light pulse from your camera that triggers the strobe, creating a wireless optical link. This means fewer cables, reduced drag, and less chance of gear malfunctions caused by tangled arms or saltwater-damaged ports. The only caveat is ensuring the receiver port remains unobstructed, which is a small price to pay for such a clean and efficient setup.
The Tactile Experience That Inspires Confidence
The tactile feedback you receive from your gear can define your entire dive. Every click, every turn, and every illuminated subject contributes to how confident you feel in your creative process. The Apollo III doesn’t just deliver light, it delivers trust. And for underwater photographers, trust in gear is non-negotiable.
Integrated aiming lights enhance both utility and environmental awareness. The red light emits 300 lumens while the white delivers 250, and both can be toggled based on shooting conditions. In dimly lit settings or during night dives, the red light is especially valuable. Its gentle glow doesn’t spook sensitive marine life like shrimps or cephalopods, yet still provides enough visibility to frame your shot. The white light works well for more general use or when guiding a buddy's attention toward a subject.
One of the most subtle yet powerful traits of the Apollo III is how naturally it becomes part of your dive. Instead of pulling you into constant adjustments, it disappears from your mental checklist. You aren’t forced to think about how to change modes or fight to get your desired output. Instead, the strobe responds fluidly, letting your attention remain on composition, timing, and storytelling. In a medium as dynamic as underwater photography, that kind of seamless integration can dramatically increase your success rate and enjoyment.
Weight is another important consideration for underwater gear, and Marelux has clearly thought this through. With its neoprene cover in place, the Apollo III achieves near-neutral buoyancy at around 115 grams. This makes it feel agile and responsive, rather than burdensome or clunky. Whether shooting with dual strobes or operating a more compact rig, the balance remains comfortably in your favor.
The craftsmanship on display here speaks not only to engineering excellence but also to a profound respect for the underwater photographer’s workflow. There’s an underlying philosophy embedded in the Apollo III that places the user’s experience at the center. It doesn’t just illuminate your subjects, it amplifies your intent, giving shape to your vision in even the most challenging aquatic scenarios.
In essence, the Apollo III isn't just a lighting tool. It's a refined partner in the creative process. It enables faster reactions, deeper engagement, and longer explorations, all while supporting a more expressive visual language. You don't adapt to this gear; it adapts to you. That shift in perspective makes all the difference.
