Lopolight Series 301 Masthead Navigation Light, 5 NM, 225 Deg, 10-32VDC, IP68, Vertical Mount

Overview

The Lopolight 301-011 Series is a 5 NM white masthead navigation light range with a 225° arc, built for vessels in the 20-50 m (65.6-164 ft) class and intended for vertical mounting on a mast or hardtop structure. It runs on 10-32 VDC, draws 4.1 W (about 320 mA at 12 V and 170 mA at 24 V), and is sealed to IP68 for spray and washdowns.

The housing measures 74.55 x 28 x 73.16 mm (2.9 x 1.1 x 2.88 in) and uses an aluminum body with a PMMA lens. Approvals include COLREG72, EN14744, IEC 60945, IACS E10, and USCG, with additional type approvals listed by ABS, M.E.D., DNV, and LR.

Key features

• 5 NM masthead light with 225° white arc for vessels 20-50 m (65.6-164 ft)
• 10-32 VDC input for 12 V and 24 V DC systems
• Power draw 4.1 W (320 mA at 12 V, 170 mA at 24 V)
• IP68 sealing and operating temperature range of -25°C to 55°C
• Compact body size: 74.55 x 28 x 73.16 mm (2.9 x 1.1 x 2.88 in)
• Approved to COLREG72, EN14744, IEC 60945, IACS E10, and USCG
• Finish choices include silver anodized, black anodized, or white ceramic coated, with single stack and double stack styles

Variants

This series is offered in multiple finishes and two stack styles to match both the look of your mast hardware and the way you want the light package arranged.

Finish options include silver anodized, black anodized, and a white ceramic coated housing. Style is either single stack (one masthead light module, pre-cabled with a 0.75 m lead) or double stack (two stacked masthead light modules, supplied with two 0.7 m leads). Across the range, the light color remains white with a 225° arc, a 5 NM rating, a 10-32 VDC input range, and IP68 sealing.

Installation and setup

Mount the unit on a solid vertical surface where the lens has a clear, unobstructed view forward. Check that antennas, spreaders, and radar hardware do not cut into the 225° sector once the boat is loaded and trimmed.

The factory connection lead is short, so many installs land it into a protected junction point inside the mast or under a hardtop, then continue down the boat with ship wiring. Use a fused DC circuit sized for the load and follow your vessel’s navigation-light switching arrangement.

Compatibility and fit

The 5 NM rating and 20-50 m vessel range suit larger yachts and workboats that require higher-visibility navigation lighting. The 10-32 VDC input works on both 12 V and 24 V DC systems without a separate converter, and the published minimum feed wire gauge is 0.5 mm2 (AWG 22).

Materials and sealing

The housing uses aluminum with an anodized finish (or a ceramic coated finish on the white option), stainless fasteners, and a PMMA lens. When mounting to stainless or carbon structures, isolate the mounting surface with an appropriate gasket or bedding to help limit galvanic corrosion, and keep the lens clean so the cut-off stays crisp.

Use cases on board

This light suits refits where a vertical masthead fixture replaces an older incandescent unit, and new builds where you want a compact light footprint on an arch or mast. It is a good match for boats that run offshore or in busy traffic lanes where a clean 5 NM masthead light helps other vessels read your heading earlier.

• Navigation light with attached connection lead(s)
• Mounting screws (M6 x 8 mm)

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.
