Freewell Underwater Light with Dual Mount for Single Action Camera Review

Imagine diving into crystal-clear waters, your action camera ready to capture the vibrant coral reefs, curious sea turtles, and schools of tropical fish darting through the blue. You hit record, but the footage comes back flat, dim, and washed out—despite the beautiful scene you witnessed with your own eyes. Sound familiar? That’s the reality for many underwater shooters who forget one critical piece of gear: a reliable underwater light.

Enter the Freewell Underwater Light with Dual Mount for Single Action Camera—a compact, powerful, and thoughtfully designed lighting solution built specifically for action camera enthusiasts. Whether you’re snorkeling in the Caribbean, freediving in the Mediterranean, or filming your latest kayaking adventure in a mountain lake, this light promises to bring your underwater world to life with rich color and sharp detail. As someone who’s spent years chasing the perfect underwater shot—only to be let down by murky footage—I was eager to put this light to the test. And after weeks of real-world use, I’m excited to share my honest, no-fluff review.

Why Underwater Lighting Matters (And Why Most Lights Fall Short)

Water is a light thief. As soon as you go below the surface, colors start to disappear. Red vanishes first—usually by 15 feet—followed by orange, yellow, and eventually all color, leaving you with a dull blue or green haze. Even in shallow, sunny waters, shadows under rocks, inside caves, or beneath overhangs can turn your footage into a dark, unrecognizable mess. Without artificial lighting, your camera’s sensor struggles to compensate, often resulting in grainy, underexposed, or color-corrected footage that looks artificial.

The Science of Underwater Color Loss

Light behaves differently underwater due to absorption and scattering. Water molecules and particles absorb longer wavelengths (like red and orange) much faster than shorter ones (blue and green). This is why photos taken without a strobe or video light often look monochromatic and lifeless. A good underwater light doesn’t just “brighten” the scene—it restores the full spectrum of color by emitting light that mimics natural sunlight, effectively “replacing” the wavelengths lost to depth.

Common Pitfalls of Budget Underwater Lights

Many affordable underwater lights promise big results but deliver disappointment. I’ve tried lights that overheated after 10 minutes, had weak output that barely reached 3 feet, or used flimsy mounts that snapped in strong currents. Some even leaked after a few dives, ruining both the light and my camera. The Freewell light, however, aims to solve these issues with a focus on durability, performance, and user-friendly design.

Who This Light Is For

This isn’t just for professional underwater cinematographers. If you’re a weekend snorkeler, a travel vlogger documenting your scuba trips, or an adventure athlete filming your underwater swims or dives, this light is built for you. It’s especially ideal for GoPro users, DJI Action camera owners, and other single-action-camera setups that need a compact, easy-to-mount solution without the bulk of full underwater housings.

Unboxing and First Impressions: What’s in the Box?

When the Freewell Underwater Light arrived, I was immediately impressed by the packaging. It came in a sleek, compact box with clear labeling and protective foam inserts—no flimsy plastic trays or excessive packaging. Inside, I found everything neatly organized and ready to use.

What You Get

• Freewell Underwater Light (Main Unit) – Compact, waterproof, and built like a tank.
• Dual Mount System – Includes both a standard action camera mount and a versatile ball joint adapter.
• USB-C Charging Cable – For quick, modern charging (no proprietary connectors).
• Wrist Strap – Handy for surface use or shallow dives.
• User Manual & Quick Start Guide – Clear, concise, and surprisingly helpful.

The light itself feels solid—no creaks, no loose parts. The housing is made of anodized aluminum, which not only looks premium but also resists corrosion from saltwater. At just 4.2 inches long and weighing 6.3 ounces, it’s lightweight enough to carry in a small gear bag or even a large pocket. The matte black finish reduces glare and gives it a stealthy, professional look.

Design and Build Quality

One thing that stood out immediately was the attention to detail. The buttons are tactile and responsive, with a satisfying click when pressed. The power button doubles as a mode selector, cycling through high, medium, low, and strobe settings. The charging port is covered by a rubber seal that snaps securely into place—no fiddly latches or weak seals here.

The dual mount system is a game-changer. The standard mount attaches directly to most action cameras (GoPro Hero 9–12, DJI Osmo Action, Insta360 GO 3, etc.), while the ball joint allows for 360-degree rotation and tilt. This means you can angle the light perfectly—whether you’re pointing it forward for wide shots or downward for macro close-ups. I tested it on my GoPro Hero 11, and the fit was snug and secure, even after multiple dives.

Performance Underwater: How Bright Is It Really?

Specs on paper are one thing—real-world performance is another. The Freewell light boasts a maximum output of 1200 lumens, which sounds impressive, but how does that translate underwater? After testing it in various conditions—from shallow reef snorkeling to deeper dives at 40 feet—I can confidently say it delivers.

Brightness and Beam Pattern

At 1200 lumens on high, the light cuts through the water with a wide, even beam that covers about a 90-degree angle. This is ideal for action cameras, which typically have wide-angle lenses. Unlike narrow-beam dive lights designed for spotting fish, this light spreads its output to illuminate the entire frame—perfect for video.

In clear water at 10–15 feet, the light restored vibrant reds and oranges to coral and fish, making the footage look almost as vivid as what I saw with my own eyes. At 30 feet, where natural light starts to fade, the difference was even more dramatic. Without the light, my footage was a blue-gray mess. With it, the colors popped, and details in the coral texture became visible.

Battery Life and Runtime

Freewell claims up to 90 minutes of runtime on high, and in my testing, it held true. I used it continuously on a 45-minute dive at 25 feet, and it still had about 30% battery remaining. On medium (600 lumens), I got close to 2 hours—more than enough for most snorkeling or shallow diving sessions. The USB-C charging is fast, too: a full charge takes about 2 hours, and a 30-minute quick charge gives you roughly 45 minutes of use on high.

Color Temperature and Accuracy

The light emits a color temperature of 5500K, which closely mimics natural daylight. This is crucial for accurate color reproduction. Cheaper lights often skew too blue or too green, which forces you to overcorrect in post-production. With the Freewell, my footage required minimal color grading—skin tones looked natural, and coral colors were rich and true to life.

Strobe Mode: A Surprising Bonus

The strobe mode isn’t just a gimmick. While I didn’t use it for signaling (it’s not bright enough for emergency use), it’s great for creative effects—like freezing motion in fast-moving water or adding dramatic lighting to underwater selfies. It’s also useful for attracting curious fish, which often swim toward the flashing light.

Mounting and Compatibility: Flexibility That Actually Works

One of the biggest frustrations with underwater lights is poor mounting options. Many lights come with fixed mounts that don’t allow for adjustment, or flimsy arms that bend under pressure. The Freewell’s dual mount system solves this beautifully.

Standard Action Camera Mount

The included standard mount fits snugly onto the bottom of most action cameras. It uses the same three-prong design as GoPro mounts, so it’s compatible with a wide range of models. I tested it on a GoPro Hero 11, DJI Osmo Action 3, and Insta360 GO 3—all worked flawlessly. The mount is made of reinforced plastic and holds the light firmly in place, even when swimming against a current.

Ball Joint Adapter: The Real Game-Changer

The ball joint adapter is where this system shines. It attaches to the standard mount and allows the light to pivot and rotate freely. This means you can angle the light downward for macro shots of sea anemones, upward to illuminate the surface from below, or straight ahead for wide reef scenes. I used it to film a moray eel hiding in a crevice—by tilting the light, I was able to highlight the eel’s face without overexposing the background.

Compatibility with Accessories

The light also has a standard 1/4″-20 threaded port on the bottom, which means you can attach it to tripods, extension arms, or even a small underwater rig. I paired it with a lightweight carbon fiber arm from my existing setup, and it balanced perfectly. This opens up possibilities for more advanced filming techniques, like using the light as a key or fill source in a multi-light setup.

Durability in Real Conditions

I tested the mount system in strong currents, rocky environments, and even accidentally knocked it against a reef (oops). The ball joint held firm, and the mount didn’t loosen or break. The rubberized grip on the joint provides just enough friction to keep the light in place but allows for easy adjustment when needed.

Real-World Testing: Where the Freewell Light Shines (and Where It Doesn’t)

To truly evaluate this light, I took it on three different underwater adventures: a shallow reef snorkel in Hawaii, a deeper dive in a freshwater lake, and a night snorkel in the tropics. Here’s how it performed in each scenario.

Shallow Reef Snorkeling (5–15 feet)

In bright sunlight, the light wasn’t always necessary—but it made a huge difference in shadowed areas. Under ledges, inside caves, and beneath overhangs, the light brought out details that would have been lost. I filmed a parrotfish sleeping in a crevice, and the light revealed the intricate patterns on its scales. Without it, the shot would have been a dark silhouette.

Mid-Depth Diving (20–40 feet)

This is where the Freewell light truly proved its worth. At 30 feet, natural light was fading fast, and colors were disappearing. With the light on medium, my footage looked vibrant and well-lit. I captured a school of angelfish swimming through a coral garden, and the reds and yellows were stunning. The wide beam ensured the entire scene was illuminated, not just a small spot.

Night Snorkeling

Night snorkeling is magical—but without light, it’s impossible to film. I used the Freewell light to explore a nighttime reef, and it performed beautifully. The beam cut through the darkness, revealing sleeping fish, crabs scuttling across the sand, and coral polyps extended. The strobe mode even attracted a curious octopus, which came within inches of the camera.

Limitations and Trade-Offs

No product is perfect, and the Freewell light has a few limitations. First, it’s not designed for deep diving—Freewell rates it to 130 feet (40 meters), which is fine for most recreational divers, but technical divers may need something more robust. Second, while 1200 lumens is bright, it’s not as powerful as some high-end dive lights (which can exceed 3000 lumens). For wide, deep dives, you might need two lights or a more powerful setup.

Also, the light doesn’t have a built-in battery indicator. You have to rely on the LED flash when charging or guess based on usage. A small LCD or color-coded LED would have been a nice addition.
