BlueRobotics NavLight LED Navigation Light for Marine & Subsea Vessels (High-Brightness)
High-brightness: 180 lumens
Compact design: M14 form factor
Deep-water rated: 1000m depth
Versatile control: Signal compatible
Durable build: 3-year design life
The BlueRobotics NavLight LED Navigation Light is an LED light crafted to enhance the visibility of unmanned surface vehicles (USVs), buoys, and various marine crafts over considerable distances. This product boasts a high level of brightness and is notably compact, featuring a G4 bulb housed within an M14 penetrator form factor.
This navigation light is capable of operating on a voltage range of 5-12 V and has a power consumption of up to 2.5 W, delivering an impressive light output of approximately 180 lumens. It includes internal circuitry that enables control via an external input signal from microcontrollers, such as an Arduino or a Navigator Flight Controller, allowing for the activation and deactivation of the light as well as the creation of flashing signals. In the absence of a control device, the light can be activated by directly connecting the input signal to a power source.
Designed for versatility, the Navigation Light is suitable for subsea applications and is rated for depths up to 1,000 meters when properly installed on an end cap or used in conjunction with a WetLink Penetrator at the cables end. This feature provides flexibility in mounting the light on various parts of the vehicle, without being confined to an enclosure end cap.
The product is equipped with a 60 cm cable, as well as an O-ring and nut to facilitate the installation process.
Please note that the usage guide should be consulted for comprehensive details on the products application and installation.
