Key features
Why choose range and sector lights
Choose the light from the approach geometry, required range, available power and monitoring needs.
Model and approval documentation
Vikingegaarden assists with the marking plan and the documentation needed for the selected light and site.
Nordic site requirements
Review exposure and seasonal conditions when selecting equipment for a harbor approach or coastal fairway.
Directional LED lighting
Aimable LED guide lights provide directional marking, with range and power selected for the approach.
Range selected for the approach
Versatile range options let you match the light to the length of the approach line, from a short harbor entrance to a long fairway.
Synchronisation and connectivity options
Daytime visibility, GPS synchronisation and remote connectivity are selected according to the light model and application.
Precise light sectors
Sector lights show red, white or green arcs depending on the vessel's angle to the channel, marking safe versus hazardous approach angles.
Emiko integration
The MBL 400S sector light offers full Emiko integration for status, alarms and remote control on the same platform as your other AtoN equipment.
How it works
How range and sector lights guide a ship into port
Aligned range lights indicate an approach line; sector lights give colour information according to the vessel's angle.
Range or leading lights are aligned along an approach line. A sector light shows different colours over defined angles. The marking plan determines the meaning and bearings of each sector; the MBL 400S provides 0.5 degree sector accuracy.
Vikingegaarden helps define the arrangement, select the light and power supply, and position, aim and commission the installation.

Ecosystem
Range and sector lights, supplied by Vikingegaarden
Our partner manufacturers build the lights. Vikingegaarden selects, delivers and supports them through AtoN House Nordic.
Vikingegaarden supplies LED range lights and the MBL 400S sector light through the AtoN House Nordic partner network. We help define the approach line and sector angles, choose the range and power needed, deliver and commission the lights and support them afterwards together with your lanterns, buoys and beacons. Where a light offers Emiko integration, its status, alarms and remote control are handled on the Emiko platform.

Product guide
Selecting range and sector lights
The choice begins with the approach geometry. Range lights and sector lights give different information to vessels approaching a harbor or fairway.
Range lights and sector lights have different roles
Range or leading lights mark an alignment. Sector lights show defined colours according to the vessel's angle relative to the channel. Both are used for harbor approaches and narrow or sensitive fairways, with their positions and characteristics specified in the marking plan.
The MBL 400S sector light
The MBL 400S is an omnidirectional LED sector light with 0.5 degree sector accuracy and a range of up to 12 nautical miles. Full integration with the Emiko platform is available for status, alarms and remote control. Other directional range and leading lights use aimable housings and adjustable brackets.
Positioning, aiming and commissioning
A range light only works if it points exactly where it should. Directional lights are mounted in aimable housings on adjustable brackets and aligned precisely along the approach line during commissioning; sector lights are configured so each colour boundary falls on the intended bearing. Vikingegaarden helps define the approach line and sector angles, chooses the range and power needed, delivers and commissions the lights and assists with the applicable marking documentation.
Planning the complete installation
Provide the approach line or sector bearings, required range, power availability and site conditions. Vikingegaarden supplies model documentation and helps specify monitoring and service requirements. MarineGuard combines a mast, selected light, backup power and monitoring for fixed installations.
For buoy or fixed marking without an approach alignment or sector requirement, compare our LED marine lanterns.

Good to know
Frequently asked questions about range and sector lights
What is the difference between a range light and a sector light?
Range or leading lights mark an alignment into a harbor or fairway. A sector light shows different colours over defined angles. The site geometry and marking plan determine which arrangement is appropriate.
What does the MBL 400S offer?
The MBL 400S is an omnidirectional LED sector light with 0.5 degree sector accuracy and a range of up to 12 nautical miles. Full integration with the Emiko platform is available.
What information is needed for a proposal?
Send the approach geometry, sector bearings if required, intended range, available power and site conditions. Vikingegaarden helps select, position and commission the lights and assists with the marking documentation.
Can the lights be monitored remotely?
Connectivity and GPS synchronisation options depend on the selected range light. The MBL 400S offers full integration with the Emiko platform for status, alarms and remote control.
Can the light be supplied with a mast and backup power?
Yes. MarineGuard combines the mast, selected lantern or beacon, power supply and monitoring in a configured installation.
Is every port entry light a range light?
Port entry lighting includes different optical arrangements. A range or leading light is used for an alignment, while a sector light gives angular colour information. Confirm the intended function and optical arrangement when selecting the product.
