Overview

The Lopolight 201-021 Series is a 3 NM, 360° all-round white navigation light for horizontal mounting with an FB (flat base) POM mounting system. An attached 6 m cable helps when you need to reach a junction point inside a mast or down through a pole.

It runs on 10-32 VDC for typical 12V and 24V DC systems and draws 3.6 W (about 300 mA at 12 VDC, 148 mA at 24 VDC). The housing is sealed to IP68 and the light body measures Ø92.5 mm x 36 mm, which keeps the mounting footprint tidy on a mast bracket, spreader base, or antenna-style pole.

This model is intended for vessels in the 12-20 m range and is used where an all-round white light is required by your navigation light plan, including common masthead and anchor positions.

Variants

This light is offered in multiple configurations that differ by exterior finish.

Specifications such as 3 NM visibility, 360° white output, IP68 sealing, and 10-32 VDC input stay the same across these finish options.

• 201-021-FB 6M: Finish Silver. Matches the look of bare aluminum spars and silver-toned hardware.
• 201-021-FB-B 6M: Finish Black. Blends with black anodized spars and darker mast fittings.

What’s included

• Navigation light with attached cable
• Installation guide

Compatibility and fit

The 360° white pattern is meant for installations where the light must be visible all the way around the vessel. Confirm that the mounting location has clear line of sight and that the light arrangement on your boat meets the requirements for your length and operating mode.

Installation and setup

The FB base format is intended for horizontal mounting, such as on a mast bracket or a pole mount where wiring is routed through the structure. Plan a clean cable route, protect the cable where it passes through metal, and seal any deck or mast penetrations to keep water out.

Electrical and system integration

Connect to a 10-32 VDC supply and account for the 3.6 W load when sizing your circuit. With a minimum feed wire gauge of 0.5 mm2 (AWG 22), longer runs are typically handled by bringing the attached 6 m cable to a nearby junction and continuing with appropriately sized vessel wiring.

Maintenance and care

Rinse salt and grime off the lens and housing during regular washdowns and inspect the cable jacket for chafe where it enters the mast or pole. Keep fasteners snug and avoid abrasive cleaners on the lens and anodized finish.
