Overview

The Lopolight 201-011-15M is a white masthead navigation light with a 225° sector and 3 NM visibility, supplied for vertical mounting with a 15 m cable. It runs on 10-32V DC and draws 3 W (232 mA at 12VDC, 127 mA at 24VDC), so it works on standard 12V and 24V onboard systems.

The housing measures 74.55 x 28 x 73.16 mm (2.9 x 1.1 x 2.88 in) and is sealed to an IP68 rating for exposed mounting locations. It is rated for vessels 12-20 m and approved to COLREG72, EN14744, IEC 60945, IACS E10, and USCG.

What's included

• Navigation light with 15 m cable
• 2 mounting screws (M6 x 8 mm)
• Installation guide

Compatibility and fit

This is a masthead (steaming) light that needs a clear forward-facing 225° arc. Install it on the vessel centerline and keep antennas, wind instruments, and rigging out of the light sector so the beam is not shadowed.

Installation and setup

Mount vertically using the supplied M6 fasteners on a flat surface. Route the cable with strain relief at the light and a drip loop before the cable enters the mast or cabin, then protect the run at mast exits and deck glands to avoid chafe from vibration.

Electrical and system integration

Wire it into a 10-32V DC navigation-light circuit controlled by your switch panel or lighting controller. The recommended minimum feed wire size is 0.5 mm² (AWG 22), and the circuit should be protected with an appropriately sized fuse or breaker for the load and the cable run.

Materials and sealing

The body uses silver anodized aluminum with a PMMA lens and A4 stainless hardware to suit saltwater exposure. The IP68 seal and operating range from -25°C to 55°C help it stay stable through cold starts, hot sun, and regular washdowns.

Use on board

This light fits powerboats and motorsailers in the 12-20 m range that need a certified 3 NM masthead light, especially when the wiring run from the masthead to the distribution point is long. It also suits refits where the existing cable chase is tight and a pre-attached 15 m lead simplifies routing.

Maintenance and care

Rinse salt off the lens and housing during routine washdowns and keep the lens clear of dried salt film. At least once a season, inspect the cable where it passes through glands and mast exits, and re-seal any penetrations if you see moisture tracking.
