Lopolight 201-011 Masthead Light, 3nm, Horizontal Mount, FB Flat Base

Overview

The Lopolight 201-011 Series is a 3 NM white masthead navigation light with a 225° sector for horizontal mounting on vessels in the 12 to 20 m range.

It runs on 10-32 VDC so it fits both 12V and 24V systems, and the enclosure is rated IP68 for weather and washdowns. The body diameter is Ø92.5 mm across the range, with overall height depending on single or double stack (36 mm or 58 mm).

This series uses the FB (flat base) POM mounting system and comes precabled, which keeps the install clean on a mast, radar arch, or pole where space is limited and vibration is normal.

What's included

• Navigation light, precabled with a 0.75 m shielded marine grade cable
• Installation guide

Installation and setup

The FB base mounts on a flat surface; the cable passes through a 7 mm center hole and the base is aligned so the arrow points forward and stays parallel with the vessel centerline. The light twists onto the base and is secured with a locking screw.

If the mounting surface is rough, adding sealant around the base helps keep water out. Keep the lens clear of obstructions so the 225° sector is not shaded by antennas, brackets, or other fittings.

Electrical and system integration

Supply voltage is 10 to 32 VDC. For single stack lights the cable has two conductors (red positive, black negative). For double stack lights there are four conductors so each light can be powered and switched separately (Light 1: red positive and black negative; Light 2: white positive and green negative).

Use a fuse or circuit breaker under 2 A (slow) and route the cable where it will not chafe or sit next to high heat sources or large electric motors.

Materials and corrosion resistance

The housing is anodized aluminum with a 25µ surface finish, paired with a PMMA lens and A4 stainless screws. Epoxy and polyurethane sealing materials are used to keep moisture out in a saltwater environment.

Maintenance and service life

Cleaning is straightforward: wipe with a damp cloth and a mild detergent. Avoid alcohol or thinner on the lens.

An internal end-of-life signal briefly blanks the light after startup to indicate status, with longer off periods as the projected 50,000-hour lifetime is reached.

Use on board

This light suits powerboats and sailboats that need a 3 NM, 225° masthead light mounted horizontally on a mast, arch, or pole. The double stack versions support installations where two separately switched masthead lights are required in the same location.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
