Sea Bright LED - Lumen Subsea Light for ROV

Sea Bright LED - Subsea ROV Light (50W, 80W, 150W)

DWTEK’s flagship Sea Bright LED is available in 50W, 80W, and 150W models, delivering over 45 lm/W of brightness. The series is housed in a lightweight yet rugged body, depth-rated to 6,000 meters, and equipped with PWM dimming and over-temperature protection. Sea Bright LED lights are designed to provide powerful area illumination, making them an excellent choice for ROVs conducting inspection, maintenance, and recovery operations in deep-sea environments.

Key factors to consider when choosing a ROV light

Selecting the right ROV lights is essential for mission efficiency and safety. Below are four critical factors to evaluate when selecting a subsea lighting solution.

Consideration 1: Lumen strength and color temperature

Brightness, measured in lumens, determines how well ROV lights illuminate surroundings. Tasks like inspection or manipulation typically require 1,347–7,110 lumens. Cool white color temperature (5,000K–6,500K) ensures true-color visuals for cameras in murky waters, enhancing clarity for high-definition imaging.

Consideration 2: Beam type: Spot vs. flood

The light beam pattern significantly impacts the field of view. Spot beams offer narrow, concentrated light for long-distance visibility, while flood beams cover wider areas for general illumination. Matching the beam type to the ROV’s application ensures better visual coverage and operational accuracy.

Consideration 3: Depth rating, material durability, and operating temperature

ROV lights must endure both high pressure and harsh environmental conditions. Depth ratings typically range from 2,000 to 6,000 meters. Look for housings built from marine-grade materials—such as anodized 6061-T6 aluminum or titanium—which resist corrosion and maintain structural integrity at depth. In addition, DWTEK’s ROV lights are rated to operate reliably within temperatures from -10˚C to 40˚C, making them suitable for cold and thermally variable subsea environments.

Consideration 4: Mounting and electrical interface

Check compatibility with your ROV’s mounting system—modular designs are preferred for flexibility. The electrical interface must support your system's voltage, current, and control signals. DWTEK offers plug-and-play LED modules optimized for easy integration with nearly all observation and work-class ROVs.

Real-world use cases for ROV and subsea LED lights

ROV lights play a vital role across various underwater industries. Their high-lumen output and rugged build make them indispensable for both routine tasks and emergency operations.

Offshore inspection: Pipelines, rigs, and wind farms

Subsea inspections are essential for the integrity of offshore oil, gas, and renewable assets. Subsea lights for ROV illuminate underwater pipelines, jacket structures, and turbine bases, even in turbid and deep water. DWTEK’s lighting systems are frequently used in wind farm O&M and rig inspections, providing clear visibility at depth.

Search and recovery missions

Strong LED lights help ROVs locate sunken objects, wreckage, or evidence during emergency or salvage operations. Spot beam configurations are ideal for penetrating murky water and enhancing the effectiveness of onboard cameras systems.

Oceanographic research

Researchers rely on ROV-mounted subsea LED lights for deep-sea surveys, specimen collection, and environmental monitoring. Consistent lighting supports accurate color identification and long-duration deployments with minimal maintenance.

Aquaculture monitoring

ROVs equipped with subsea LED lights in fish farms and marine hatcheries monitor stock health, feeding behaviors, and net integrity. Flood beam lights provide wide coverage, helping operators conduct real-time assessments.

Frequently asked questions about ROV and subsea lights

Q1. How many lumens do I need for adequate underwater visibility?

ROV lights with 1,347–7,110 lumens are typically sufficient for general inspection and navigation. Work-class operations or deep-sea tasks may require higher outputs—up to 7,110 lumens—to effectively penetrate darkness and turbid conditions.

Q2. Can ROV lights be dimmed or controlled remotely?

Yes. Most professional-grade LED lights, including DWTEK’s models, offer remote dimming. This allows operators to adjust brightness based on environmental visibility and task precision.

Q3. Can I use DWTEK ROV lights with non-DWTEK ROV systems?

Absolutely. DWTEK’s lighting systems and subsea connectors are designed for cross-platform compatibility. DWTEK supports integration with various ROV brands and custom underwater vehicles through custom pin-outs and connector configurations.

Q4. How long do ROV lights last, and what maintenance is required?

DWTEK’s ROV lights feature industrial-grade LEDs with lifespans of up to 50,000 hours. Maintenance is minimal—typically limited to cleaning the lens, checking seals, and periodic inspections of connectors for corrosion or mechanical wear.
