Over the years the Lopolight team has worked with a large number of Navy, Military and SAR projects, each with their own set of requirements and challenges.

Extreme environmental demands, such as immunity to 1500V/m Radar, 50G shock, 65 bar pressure, stealth design or just tamper proof are features that we master. We take the otherwise illegal dimmable navigation light as for granted in this field – but add that we still can monitor it in its dimmed state – even with the ice-class defroster active!

Lopolight has been supplying Navies with rugged navigation lights, starting with very fast small craft for special forces, that were in need for something that can take the extreme vibration and water pressure from high speed close to the water.

All special Navy lights are in our product range, such as Deceptive lighting, IR follow-me lights, Blue Convoy lights, Wake lights, MOB signaling systems, Obstruction lights, Waterline security lights, Perimeter lights plus many unique fittings are available. That our lights are NVIS/NVG is in the DNA of every product.

Several projects with autonomous vessels allow us to add that we have that in hand. The only military field where we come up short is in the air. Below you will find a few examples of our work.

With NATO/OTAN manufacturer registration, strong and surveyed quality management systems and with a good track record of honoring confidentiality and signed NDA’s we are ready accept your challenge.


All our military lights are complying to the relevant civilian standards and are designed and built from the base of the professional series lights. Recently the Lopolight team have successfully concluded several military standards tests, demonstrating that the Lopolight systems are fit for purpose.


MIL-STD-461G is an important testing standard. It ensures that the Lopolight Navigation light systems will function properly within electromagnetic environments and avoid releasing energy that could potentially cause electromagnetic interference (EMI) with nearby devices. For those interested, we comply to sub-standards: CE101, CE102, CS101, CS106, CS114, CS116, RE101, RE102, RS101, RS103, RS105 – the last one is an EMP pulse of 50000 Volts/meter!


MIL-DTL-901E is high-impact shock test standard. The tests were performed on a shock machine on land in the proverbial “hammer test” that involves a moving weight that is dropped from various heights, imparting high transient shock to the navigation light system that is affixed to an anvil plate. Amazing video footage came out of this test at E-Labs in the USA.


MIL-STD-167-1A is a military standard published by the U.S. Department of Defense and used by test engineers to assess the impact of mechanical vibrations on Navy shipboard equipment. This test is performed directly after the 901E shock test on the same equipment, it passed with flying colours.

MIL-STD 1399

MIL-STD 1399 is a military standard approved for use by the Naval Sea Systems Command, Department of the Navy. The purpose of MIL STD 1399 is to define the standard interface requirements and constraints applicable on the design of shipboard user equipment that will utilize shipboard alternating current electric power.

The Lopolight system has been tested to MIL-STD-1399 SECT300 PART1.



The primary task of the navigation light system is to provide safety, and no one knows that better than the team at Lopolight. However, a warship needs more, the lights we install on warships are designed to meet the unique requirements, such as dimmability – whilst remaining in control. >>

The Arctic area is increasingly contested and therefore lights that work when you need them – already de-iced – are part of our offering. 

The EMC signature is close to non-existent, it will not be a Lopolight that gives your position away or degrades your AIS & VHF signals.

Special task lights, IR lights, wake lights and combinations are available.

Due to the compact form factor and the ability to combine lights on the same location the Lopolight Navigation lights makes the installation of deceptive lighting both possible and attractive.

As project management, design and production are housed in the same building at Lopolight, we offer flexibility in the product design to fit your requirements – and with a quick turn-around.



Lopolight has been involved with several autonomous vessel projects such as conversions from manned to unmanned, small minesweeper vessels or even autonomous harbor patrol vessels. We see the special demands for these vessels in 2 areas: First, the lights onboard should possess the necessary logic, like automatic switch over between primary and backup lights, and automatic switch over of power source from the primary to the backup – and inform the control center about such incidents, but without the need of intervention. Even the use of the optional built-in defroster system is automatic.

Secondly, we need to provide a control and monitoring solution that is flexible and can be configured to interface to the onboard or shore-based systems in several ways such as over a serial communications interface, N2KView or via Modbus TCP/IP, while at the same be ready for manned operation with onboard controls.
