Overview

The Lopolight 300-112G2ST is a 3 nautical mile, 360° all-round white navigation light with a double-stacked light output, made for horizontal mounting on larger vessels. It runs on 10-32VDC for 12V and 24V systems, draws 4.2W (270mA at 12V, 176mA at 24V), and carries an IP68 rating for exposed masthead installations.

The body measures Ø92.5mm x 96.5mm and weighs 1.31kg. Construction uses silver anodized aluminum (25µ) with a PMMA lens, A4 stainless steel screws, and fully sealed internal components with epoxy and polyurethane. Approval coverage includes COLREG72 along with EN14744, IEC 60945, IACS E10, USCG, ABS, M.E.D., DNV, and LR.

This style of 360° light is used where you need an all-round white arc with clear visibility and minimal shadowing from antennas or rigging. It is a solid fit for yachts and commercial builds over 50m where a 3nm, double white all-round light is part of the navigation light plan.

What’s included

• Navigation light assembly with aluminum base
• HDPE base plate

Installation and wiring

Plan the mounting spot so the light has a true 360° view with as little blockage as possible from antennas, domes, stays, or hardtops. Because the unit is specified for horizontal mounting, install it on a level surface and tighten fasteners evenly to keep the base sitting flat.

Power is DC in the 10-32V range. The minimum feed wire gauge is 0.5mm2 (AWG22). Use a protected navigation-light circuit, keep connections dry inside the mast or structure, and route the cable away from heat and high-current motor runs where practical.

Compatibility and fit

This light is intended for vessels over 50m and is commonly used in setups that call for a double white all-round light arrangement. Verify your vessel’s navigation-light plan and mounting height requirements before drilling, especially on commercial builds where the light arrangement is tied to compliance documentation.

Maintenance and care

Rinse salt residue from the housing and lens as part of regular washdowns and wipe the lens with a soft cloth to keep the light output clean. Periodically check fasteners for tightness and inspect the connector for a secure, dry fit after heavy weather or mast work.
