Key features

Key features of the ML series marker lights

Compare intensity, power and mounting for the position or equipment being marked.

A line of ML 100 marker lights floating on a net line at blue hour, only the float discs and lit lanterns above the water.

LED output by model

The listed intensity ranges are 5 to 6 cd for ML 100, 5 to 18 cd for ML 200 and 5 to 70 cd for ML 300. Confirm the required colour and configuration when ordering.

IALA flash characters

Flash rate and character are configurable to meet regulatory and operational requirements. The ML 200 and ML 300 support any IALA flash character.

Four LED colours

Each model is available in four colours, including white, yellow and red, so the light matches international maritime marking standards.

Battery or external power

The ML 100 runs on three D cells and the ML 200 on a 4.5 VDC battery supply, while the ML 300 is powered from 10 to 27 VDC.

Daylight sensing

The ML 200 includes daylight sensing for automatic operation. Confirm sensor functions for the selected model and configuration.

Synchronised flashing

Synchronisation coordinates several lights on an installation. Master and slave operation is documented for the ML 200.

Marine housing

The ML series is designed for marine marking. Confirm the model-specific enclosure and immersion rating for the intended installation.

Modular, low maintenance

Compact units built for long periods in exposed and remote locations. Modular construction allows quick servicing in the field.

Applications

Applications for marine marker lights

Anywhere a position, boundary or hazard has to stay visible after dark.

Buoys and mooring lines

Illuminate floating buoys and fixed mooring points for safe navigation around ports, shipping lanes and aquaculture zones.

Nets and aquaculture

Mark net positions and farming boundaries in coastal and offshore waters, with the model selected for mounting, power and intensity.

Platforms and wind farms

Highlight infrastructure, exclusion zones, seismic cable areas and temporary work sites at night and in poor visibility.

Port entrances and barriers

Improve visibility at approach points, floating barriers, containment lines and protected environmental zones.

How it works

How the ML marker lights are chosen and installed

Pick the intensity class for the distance and structure, set the flash character and colour, and mount the light on the buoy, line or platform.

Choose the ML model from the required intensity, mounting and power source. ML 100 is the compact battery powered option for nets and lines. ML 200 adds a programmable light character, synchronisation and daylight sensing. ML 300 uses an external DC supply for aquaculture and offshore installations.

Select the colour and flash character for the marking plan, then confirm the mounting, synchronisation and service requirements for the supplied version.

  • Choose the model by intensity: ML 100 (5 to 6 cd), ML 200 (5 to 18 cd) or ML 300 (5 to 70 cd)

  • Select the LED colour and the IALA flash character required for the marking

  • Mount on buoys, mooring lines, nets, seismic cables or platforms; power by battery or DC supply

  • Synchronise several lights so an installation flashes as one signal

  • Confirm daylight sensing and maintenance requirements for the selected model

Ecosystem

Marker lights in the Vikingegaarden AtoN range

Vikingegaarden supplies the ML series through AtoN House Nordic alongside marine lanterns, beacons and personal strobe lights.

Vikingegaarden A/S in Vonge, Denmark, supplies the ML marker lights together with the rest of its aids to navigation portfolio: lanterns, radar beacons, range lights, physical and virtual buoys and the AQ-4 MkII strobe light. We help you pick the right intensity class, colour and flash character for the site and can advise on synchronisation across a whole installation. Sales and support are handled from Denmark on +45 7580 3960.

Product guide

Choosing an ML marine marker light

The ML 100, ML 200 and ML 300 serve different mounting and power requirements. Select the light around the equipment or boundary being marked.

Nets, aquaculture and offshore structures

The ML range is used on fishing nets, mooring lines, buoys, seismic cables and offshore installations. Fish farm operators and marine contractors specify the light colour and flash character for the marking scheme, together with the required intensity and power supply.

Comparing the ML models

ML 100 is a compact light for nets and lines, powered by three D cells. ML 200 is a battery powered option for buoys and structures, with programmable IALA flash characters, master and slave synchronisation and a daylight sensor. ML 300 uses an external 10 to 27 VDC supply and flange mounting for aquaculture and offshore applications.

Compare the model specifications below and ask for the current data sheet for the colour and version required.

Synchronisation and automatic operation

Coordinated flashing can help identify a line of marks or an installation boundary. Specify the flash character and confirm the synchronisation arrangement for the selected model. Daylight sensing is documented for ML 200; functions on other configurations should be confirmed before ordering.

Marker light, marine lantern or personal strobe

For buoy and fixed navigation marking, compare LED marine lanterns. For a portable light attached to personnel or equipment, see the AQ-4 MkII strobe light Lattice masts. Vikingegaarden supplies and supports these products from Denmark.

Good to know

Frequently asked questions about marker lights

Which ML model should I choose?

Compare the required intensity, power supply and mounting. ML 100 is the compact option for nets and lines, ML 200 serves buoys and structures with synchronisation and daylight sensing, and ML 300 uses external DC power for aquaculture and offshore applications.

How are the lights powered?

It depends on the model. The ML 100 runs on three D size battery cells, the ML 200 is battery powered at 4.5 VDC and the ML 300 takes an external 10 to 27 VDC supply. Battery runtime figures are not published; contact us for the current data.

Can several marker lights flash together?

Synchronisation options are available within the ML range. Master and slave synchronisation is documented for ML 200. Confirm the arrangement for the selected models and installation.

Do the lights switch on automatically?

The ML 200 has a daylight sensor for automatic operation. Ask Vikingegaarden to confirm the available sensor functions for the other models and the version supplied.

What should I provide for a marker light proposal?

Describe the net, buoy, line or structure to be marked, the required light character and colour, the viewing requirement and available power. Include any need to synchronise several lights.

Is a marker light the same as a personal strobe?

The ML series marks marine equipment, buoys and structures. The AQ-4 MkII is a portable personal strobe with flashing and steady modes.
