Overview
The Lopolight Double Stacked Ice-Class navigation light is a horizontally mounted, IP68-rated LED navigation light built with a de-icing heater for cold-weather operations. Ice-class versions run on 19 to 32 VDC, and the built-in 25 W heater is controlled by an internal temperature sensor that activates below 3°C and switches off at 15°C.
Each unit contains two independent light modules, a primary and a secondary, that can be powered separately through the 5-pin connector. The housing is machined from 6082 aluminum with an anodized finish, and the interior is fully potted to help keep water and vibration from reaching the electronics.
This range is typically specified for vessels over 50 m (164 ft) and is used where certified navigation lighting needs to stay visible in heavy spray and freezing conditions. The exact light sector, color, and visibility rating depend on the configuration listed below.
Key features
- Double light with separate primary and secondary power paths for redundancy (5-pin connection with dedicated power and ground for each light)
- Ice-class de-icing with a 25 W heating element and temperature sensor control (on below 3°C, off at 15°C)
- 19 to 32 VDC input range for the ice-class configurations
- IP68 sealing with fully potted electronics for washdown exposure and vibration
- Horizontal mounting on a 400-037 aluminum base with an HDPE base plate
- Side cable entry with two M25x1.5 threaded gland ports for clean routing
- Meets COLREG72, EN14744, IEC 60945, and USCG (UL1104) requirements
Variants
This product is offered in multiple configurations to match different navigation-light positions and visibility requirements.
Across the range, the double primary and secondary layout, ice-class de-icing approach, IP68 sealing, and horizontal mounting style remain consistent. The light sector, light color, and visibility rating vary by configuration.
- 300-138-PRO-I: Nanometers 6NM. 225° white masthead light with visibility rated for more than 6 nautical miles; power consumption is 7 W in normal operation and 32 W during de-icing at 24 VDC.
- 301-108ST-PRO-I: Nanometers 3NM. 112.5° green starboard sidelight with visibility rated for more than 3 nautical miles; power consumption is 2.3 W in normal operation and 27.3 W during de-icing at 24 VDC.
What’s included
- Navigation light mounted on 400-037 aluminum base
- HDPE base plate
- 3 x M6x14 mounting screws
- 2 x M25x1.5 cable glands for 9 to 17 mm cable diameter
- 5-pin connector plug
- 2 x reduction kits (M25 to M20 or M16) for 4.5 to 13 mm cable diameter
- Installation instructions
Installation and mounting
These lights are built for horizontal mounting, with the cable glands entering from the side. Plan the mounting surface so the base sits flat, and confirm the light’s sector orientation matches the vessel centerline and required navigation-light position.
Use the included glands and reduction pieces to match your cable diameter and keep the seal intact. Leave enough service loop and clearance to access the connector and gland area without stressing the wiring.
Electrical and system integration
Ice-class configurations operate on 19 to 32 VDC. The connector supports separate power and ground for the primary and secondary light circuits, which helps when the installation calls for redundancy or independent monitoring of each light module.
Account for the higher current draw during de-icing when sizing wiring and protection. At 24 VDC, the 6NM masthead configuration draws about 0.29 A normally and about 1.3 A when heating, while the 3NM starboard configuration draws about 0.18 A normally and about 1.1 A when heating.
Use on board
This range is a good match for commercial vessels, superyachts, and expedition boats that run in freezing spray or ice-prone waters and still need navigation lights that stay visible and correctly sectored. It also suits high-vibration installations where potted electronics and IP68 sealing matter.
Maintenance and inspection
Rinse salt buildup from the housing and gland area as part of normal deck washdowns, and check that cable glands remain tight after seasonal temperature swings. In cold climates, periodic visual checks of the light sector and lens area help confirm the de-icing function is keeping the optics clear.
Shipping
