Overview

The Lopolight 300-112G2-PRO-I is a 3 NM, 360-degree white navigation light with an automatic de-icing function for operation in freezing conditions. It runs on 20-32VDC and is intended for vessels over 50 m where long-range visibility and continuous operation matter.

The de-icing function is controlled by an internal sensor, increasing power draw when needed while keeping the light output consistent for night running. The housing is IP68-rated for wet decks and washdowns, and the compact footprint (Ø92.5 mm x 89.5 mm) helps when mounting space is limited on rails, platforms, and superstructure faces.

Key features

• 360-degree white light with 3 NM visibility and light intensity greater than 15 cd
• Automatic de-icing function controlled by an in-built sensor for sub-zero operation
• 20-32VDC input for common commercial DC systems
• Power draw: 4W in normal mode, 21W in de-icing mode (light on)
• IP68-rated for exposure to spray, rain, and washdowns
• Horizontal mounting with plug-connector connection for service access
• Includes three cable glands for 4.5-10 mm, 7-13 mm, and 9-17 mm cable diameters
• Housing and fasteners selected for harsh marine environments: black hard coat anodized aluminum, PMMA lens, and A4 stainless steel screws

What’s included

• Navigation light with plug connector
• Three cable glands for 4.5-10 mm, 7-13 mm, and 9-17 mm cable diameters

Installation and setup

This light is built for horizontal mounting. Confirm you have clear all-round visibility for a 360-degree light and that nearby structures, antennas, or cranes will not shadow the beam.

Use the supplied cable glands to match your cable diameter and maintain a watertight seal at the entry point. On exposed mounting locations, careful sealing around fasteners and the mounting surface helps prevent water ingress into the structure beneath the light.

Electrical and system integration

Wire the unit to a protected 20-32VDC circuit and size the protection to suit the vessel’s electrical standards, accounting for the higher draw during de-icing operation. The built-in sensor manages when de-icing is active, so the load profile can change in cold weather.

Compliance and operational fit

Approved to COLREG72, EN14744, IEC 60945, IACS E10, USCG, ABS, M.E.D., DNV, and LR, with conformance to USCG Commandant Instruction M16672.2. This is a good match for commercial operators and high-latitude routes where ice, spray, and vibration are part of normal service.

Maintenance and care

Rinse salt deposits as part of routine washdowns and check the lens for buildup that can reduce visibility. During periodic inspections, confirm the cable gland seal remains tight and that the mounting hardware stays secure after vibration and seasonal temperature swings.
