Lopolight 300-037 Series LED Masthead Navigation Light, 5 NM, 225° White Light, Vertical Mount, Bottom Cable Exit, 20-32VDC, IP68

Overview

The Lopolight 300-037 Series is a 5 NM white masthead light (225°) for vertical mounting, with the cable exiting from the bottom.

It runs on 20-32 VDC for 24 V systems, draws 7 W, and is sealed to an IP68 rating for exposed mounting where spray, washdowns, and vibration are normal. Output is rated at more than 52 cd, and the housing size is 107 x 92.5 x 74 mm (4.2 x 3.6 x 2.9 in).

Approvals cover COLREG72 and include EN14744, IEC 60945, IACS E10, USCG, and M.E.D., which helps when you are matching an existing compliance package on larger yachts.

Key features

• 5 nautical mile visibility with a 225° white masthead sector for vessels 20-50 m
• 20-32 VDC input (24 V systems); 7 W draw (about 290 mA at 24 V)
• IP68 sealing with potted electronics for wet locations and constant vibration
• Vertical mount body with bottom cable outlet for cleaner routing through the mounting surface
• Minimum feed wire gauge of 0.5 mm2 (AWG 22) and an attached cable lead around 0.7 m
• Aluminum housing with an anodized finish, a PMMA lens, and A4 stainless fasteners in the light assembly

Variants

This light is offered in multiple configurations based on exterior finish.

The finish changes the look on deck while keeping the same 5 NM white masthead output, vertical mount format, and bottom cable direction.

• 300-037-CD: Finish Silver. Matches bare aluminum spars and polished metal fittings without standing out.
• 300-037-B-CD: Finish Black. Suits dark paint schemes, carbon masts, and black hardware for a consistent exterior look.

Compatibility and fit

This is a masthead (steaming) light sector, intended for forward visibility on power-driven vessels when installed on the vessel centerline and aligned to the marked zero line on the housing. It is sized and rated for the 20-50 m vessel range, which typically aligns with 24 V DC electrical systems.

With a vertical mounting profile and a bottom cable exit, it works well on mast supports, superstructure faces, and dedicated light brackets where you want wiring hidden behind the mounting surface.

Installation and wiring

Plan the mounting so the 225° sector is not blocked by rails, antennas, or hardtops. The unit mounts to a vertical surface using M6 fasteners; mounting bolts are not supplied, and a corrosion barrier is recommended when joining dissimilar materials.

Route the cable through a proper deck or bulkhead gland to maintain the IP68 seal and support the cable against vibration. Wire to a switched 24 V DC navigation-light circuit with appropriate circuit protection, and confirm polarity before energizing.

Use cases on board

This configuration fits larger motor yachts and commercial-style builds that need a long-range masthead light on a 24 V system. It is commonly installed on the mast, wheelhouse front, or a forward superstructure face where the light has a clear view ahead for coastal cruising and offshore runs.

Maintenance and care

Rinse the housing and lens with fresh water after salt exposure and clean the lens with a mild boat soap to keep the beam edge sharp. Periodically check mounting fasteners and cable support points, especially after heavy-weather passages or frequent high-speed runs.

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.
