Product description
CT4011 Subsea LED Light
The CT4011 subsea LED light is a high-output underwater lighting solution designed for professional commercial diving, ROV and offshore inspection applications. Available in both 24 VDC and 110/230 VAC configurations, it provides exceptional illumination while offering the flexibility to integrate with a wide range of subsea systems. As a result, operators can select the power configuration that best matches their equipment and project requirements.
Powerful and Even Illumination
It delivers high-performance illumination for underwater inspections, construction, observation and survey work. Its domed optical window produces a wide, even beam that reduces shadows and improves visibility across the working area.
The broad light distribution helps cameras capture clear, high-quality images in low-light environments. Consequently, the CT4011 is ideal for ROV inspections, diver operations, scientific research and offshore maintenance.
Compact Design for Easy Integration
Despite its high light output,It measures only 97.5 mm in length, excluding the connector, with a 90 mm diameter. Its compact housing allows straightforward installation on ROVs, underwater tooling, inspection skids and subsea camera systems.
The robust construction is designed to withstand harsh offshore conditions while maintaining dependable long-term performance. In addition, the compact size simplifies integration into both new and existing subsea systems.
Advanced Dimming and Control
The CT4011 subsea LED light supports a wide range of lighting control options, allowing operators to adjust brightness precisely for different underwater conditions. Available control interfaces include:
- 0–5 V analogue control
- RS232
- RS485
- Triac dimming
- PWM control
These options allow seamless integration with many ROV platforms, inspection systems and custom subsea control solutions. Furthermore, precise brightness adjustment helps optimise camera performance while reducing glare and backscatter.
C-Net Software Compatibility
The CT4011 subsea LED light is compatible with C-Tecnics C-Net serial control software when used with supported LED lighting systems. C-Net allows operators to configure and control lighting functions directly from a PC, providing convenient system management during inspections and offshore operations.
Commercial diving contractors, ROV manufacturers and offshore inspection companies use the CT4011 subsea LED light for underwater construction, pipeline inspections, marine surveys, offshore energy projects and scientific exploration. Its combination of powerful illumination, flexible control options and rugged construction makes it suitable for demanding professional applications.
Whether installed on an ROV, integrated into an underwater camera system or used as part of a fixed subsea installation, the CT4011 subsea LED light delivers reliable illumination, advanced control and dependable performance in challenging underwater environments.
