Reliable and precise monitoring of your navigation lights isneeded both for safety - and it is required by the authorities, such as Class, Flag, Maritime authorities and IMO.

Lopolight offers a broad range of navigation light control and monitoring (NLC) solutions that satisfies the needs of any maritime professional, any vessel of any size. The system is modular, allowing you to select required modules, whilst maintaining the safety of the ship and compliance with the relevant rules and standards. For simplicity we have grouped the elements into modules. So you really need only to make 3 choices to get to your solution.

1. How you want to power the NLC?
2. How many lights to control?
3. Which control head you want?


This is the core of the system for controlling and monitoring your nav lights – with the unique Lopolight monitor relay, one for each light. The system is scalable from 4 up to 60 lights.

Required for the Phoenix® power supplies. Each full size system holds up to 28 relays, several systems can be combined up to 60 outputs.

The cabinet is an optional IP66 enclosure. Available in 2 sizes. The regular cabinet that holds a NLC with room for 28 lights, double power supplies and mimic computer is 400 x 400 x 200mm (HxWxD)

The large cabinet is 600 x 400 x 300 mm (HxWxD)


Ideal for installations where space is at a premium and power supply is DC. Each compact system holds up to 14 relays, several systems can be combined up to 60 outputs.


For classed vessels we offer class approved power supplies from Phoenix®, with options of AC or DC. Extra large power supplies available for Ice Class installations.


The classic robust panel is available in 3 sizes depending on the number of lights to control 14, 21 and 28. Each panel has 4 group functions for single operation of light configurations such as Running, Anchor, R.A.M. and N.U.C. Lights can be paired automatic backup and both light light failure or power failure is constantly monitored with both audible and visible warning. You can pair the lights and any alarms are both visible and audible.

The panel has a RS-232 port that can be used for remote output/input. A NMEA 0183 interface is built-in offering status output for alarm handling systems, VDR and AMS.

More than one panel can be connected to a system allowing easy control for a double bridge installation on vessels such as double ended ferries. Remote control can easily be established via the Remote Relay Control Module, or if a classic mimic is required the Smart Controller is available.

For Navy and SAR vessels special versions of these panels with nav light dimming function are available. The panels can be waterproofed to IP67. Each panel is engraved to customer specification in language of choice.


The latest addition to our range is the interactive MIMIC panel. 

As the name indicates it presents a mimic of your vessel and through the touch interface is directly controllable from the screen. With an unlimited number of light groups, possibility of creating group interactions such as when the anchor lights are activated, the running light will turn off, this mimic panel is extremely versatile. A comprehensive alarm log is readily accessible for the oncoming watch.

The mimic panel is powered by a compact Linux computer sitting at the NLC core. It works as a webserver (TCP/IP). If more than one screen(client) is needed, then you just add a client computer that will connect to the web-server, and provide relevant alarm functions. The mimic panel system is also an excellent choice for autonomous vessels.

The computer (either webserver or dedicated client) connects to the monitor via DP or DVI and USB for touch. Lopolight can supply the monitor or we can connect to an already existing monitor. 

Based on a line drawing (side view) of your vessel we will create a mimic, set-up your lights - and the system will be ready to go!
