Weefine WFS09 Ring Strobe and 3000-Lumen Video Light
The Weefine WFS09 is a specialized underwater strobe developed for divers who require both strobe flash and continuous video lighting in one integrated device. In underwater imaging, lighting is one of the most significant challenges. Water absorbs and scatters natural light quickly, reducing visibility and causing colors to shift toward blue and green tones. Photographers and videographers working at even shallow depths often find that natural sunlight is insufficient to capture accurate colors and sharp details. To solve this problem, underwater lighting equipment such as strobes and video lights are essential.
Weefine wfs09The weefine strobe WFS09 offers a hybrid solution by combining both strobe and video light functions in a single compact unit. It integrates a 60Ws ring-shaped flash tube for still images and a 3000-lumen high-CRI COB LED light for continuous video illumination. This approach reduces the need for multiple lighting devices and streamlines underwater photography and videography systems.
On the rear of the Weefine WFS09 underwater strobe, there is a built-in HD LCD display that provides clear, real-time information about the device’s status. The screen shows settings such as strobe power level, LED brightness, mode selection, and remaining battery capacity. The LCD display also supports a 180-degree rotation, so depending on the orientation of the strobe, the display text will be correctly rotated.
Engineering Focus of the Weefine Strobe
The weefine strobe is engineered with a ring-shaped flash tube and a wide-angle glass dome to produce even illumination across subjects. With a guide number of 22 at ISO 200, the WFS09 provides strong, balanced lighting suitable for macro, portrait, and wide-angle shooting. Eleven manual flash power levels give divers precise control, allowing them to adapt lighting to varied environments such as coral reefs, wreck sites, or low-light technical dives.
For video applications, the COB LED light provides up to 3000 lumens of output with a 110° beam angle. The light has a color temperature of approximately 5000 K and a CRI of Ra 90, ensuring accurate color rendering. This is particularly important for underwater video, where poor lighting can easily result in flat or color-distorted footage.
Weefine WFA09 Strobe Battery, Charging, and Runtime
The WFS09 underwater strobe is powered by two 18650 lithium-ion rechargeable batteries, placed in a self-contained battery pack, with a capacity of 3000 mAh each. On a full charge, the unit can deliver more than 600 strobe flashes or provide continuous video light for approximately 50 minutes at maximum output. In practice, divers typically switch between flash and video light modes, allowing for extended use over multiple dives. The strobe’s recycle time is about 0.9 seconds at full power, which supports fast-paced shooting scenarios such as photographing schools of fish or tracking moving marine life.
The device includes a charging kit, and the batteries can be removed for charging between dives. The inclusion of spare O-rings and silicone grease supports proper maintenance of the waterproof seals, which is essential for ensuring reliable performance at depth.
Physical Design and Durability
The body of the weefine strobe WFS09 is machined from aluminum, providing a balance of strength and low weight. The housing is depth-rated to 100 meters (330 feet), making it suitable for recreational, technical, and professional diving. At approximately 690 grams on land and just over 130 grams in water, the unit is relatively lightweight compared to carrying both a strobe and a separate video light.
The compact form factor reduces drag underwater and simplifies equipment setup. The strobe is supplied with both a YS mount and a 1-inch ball mount, allowing it to be integrated into a wide range of underwater camera rigs. A protective silicone sleeve and a dedicated carrying case are also included to reduce the risk of damage during transport.
Light Performance and Practical Use
In photography mode, the weefine strobe produces a 140° wide beam with a color temperature of 5500 K. This spectrum closely matches daylight, helping restore the reds and yellows that are lost at depth. When shooting video, the 3000-lumen COB LED provides a wide and evenly distributed beam, making it suitable for both close-up and wide-angle videography.
Practical use scenarios include macro photography where the ring flash produces shadow-free, even lighting, and wide-angle reef scenes where the high-power strobe can illuminate large sections of coral. For videographers, the continuous light ensures that marine subjects are lit naturally without harsh hotspots. The fast recycle time is particularly useful in dynamic environments where multiple exposures are required in quick succession.
Integrated Accessories and Ease of Use
The WFS09 underwater strobe is supplied as a complete kit. Accessories include the ball and YS mounts, spare O-rings, O-ring removal tool, silicone grease, a charger, a protective sleeve, a diffuser dome, and a carry case. The diffuser helps soften the strobe output, producing more even illumination on close-range subjects. By including these accessories, the system ensures divers can set up and maintain the unit without needing to purchase additional items separately.
