The Power of COB: Achieving Ideal Light Distribution

At the heart of the Sea & Sea LX-4000SW FS lies a groundbreaking innovation – the uniquely developed COB (Chip on Board) LED arrangement. This proprietary design allows for the realization of an ideal "center light distribution" for both the wide and spot lighting modes. By strategically positioning the wide light source in a doughnut shape and the spot LEDs at the center of the emitting surface, Sea & Sea has achieved a remarkable level of optical precision and consistency.

Uniform Illumination, No Matter the Beam Angle

The COB technology employed in the LX-4000SW FS ensures that whether you're using the wide (100° beam angle) or spot (30° beam angle) mode, the optical axis is centered on the light-emitting surface. This innovative approach eliminates the common issue of uneven illumination, delivering a clean and beautiful image with well-defined, natural-looking shadows.

Bidding Farewell to Multi-Shadows

One of the most notable benefits of the LX-4000SW FS's COB design is its ability to eliminate the "multi-shadows" often associated with LED lighting. Traditional LED lights, composed of multiple light-emitting chips, can produce unnatural, obscuring shadows that detract from the clarity and visibility of your subject. The Sea & Sea solution, with its single light source COB, effortlessly overcomes this challenge, ensuring your underwater subjects are captured with a sharp, well-defined outline.

Versatile Lighting Control: Mastering the Illumination

The Sea & Sea LX-4000SW FS offers a comprehensive suite of lighting control features, empowering users to fine-tune the illumination to suit their specific needs.

Step Dimming and Stepless Adjustment

With the simple press of a button, the LX-1200SW FS allows for 4-step step dimming, enabling you to seamlessly adjust the light intensity between 25%, 50%, 75%, and 100%. For even greater precision, the stepless dimming function, operated by the left and right dimming buttons, provides 1% incremental control over the light output – a valuable tool for achieving the perfect exposure.

Memory Function: Maintaining Consistent Lighting

Particularly useful for videographers, the LX-4000SW FS's memory function ensures a smooth and consistent lighting experience. When the light is turned off and then back on, it automatically resumes at the same intensity as when it was previously powered down, eliminating the need for repeated adjustments.

Intelligent Features for Effortless Integration

The Sea & Sea LX-4000SW FS is equipped with a suite of intelligent features designed to streamline your underwater imaging workflow.

Flash Sensor Function: Automatic Synchronization

Integrating a "flash sensor function," the LX-4000SW FS can detect the strobe light from your camera's flash and automatically turn off the light, preventing it from being captured in your images. This seamless synchronization allows you to utilize the light as a focus aid without compromising your final shots.

Compact and Ergonomic Design

Thoughtfully designed with user-friendliness in mind, the LX-4000SW FS boasts a compact, palm-sized body that weighs a mere 163g underwater. This streamlined form factor, combined with the centralized spot light layout, ensures a comfortable and maneuverable experience, allowing you to effortlessly position the light as needed.

Robust and Reliable Performance

Designed to withstand the rigors of underwater photography, the Sea & Sea LX-4000SW FS is built to deliver reliable performance in even the most challenging environments.

Thermal Management and Safety Measures

The light automatically switches to a protective mode when the head reaches 55°C (131°F), reducing the output to 20% of its maximum to prevent overheating. Additionally, the battery indicator flashes to alert you when the light enters a "safety mode," providing a 10-minute countdown before the light shuts off.

Dual Charging Options

Accommodating the needs of discerning underwater photographers, the LX-4000SW FS offers two convenient charging methods. Users can opt for direct charging by connecting the supplied rear charge plug to the magnetic terminal on the back of the body, or they can remove the compact Li-ion battery for standalone recharging, ensuring uninterrupted shooting sessions.

Expandable Lighting Power

The Sea & Sea LX-4000SW FS is part of the versatile LX series, which allows users to upgrade the light head to higher-end models with increased maximum luminous flux. This modular design approach enables you to future-proof your investment, seamlessly transitioning to more powerful lighting solutions as your needs evolve.
