Lopolight Series 301-011 - Masthead Light - 5NM - Horizontal Mount - White- Black Housing

The Lopolight Series 301-011 Masthead Light is a compact LED navigation light designed for vessels requiring reliable, visible masthead illumination. This 5-nautical-mile visibility light combines efficient LED technology with Lopolight's proven design philosophy: precision engineering that delivers marine-grade performance without excessive bulk or complexity. The horizontal mount configuration and white light output make this unit well-suited to sailboats, fishing vessels, and cruising yachts that demand consistent night visibility during coastal and offshore operation.

The 5NM range specification indicates effective visibility distance under standard atmospheric conditions, a critical factor for collision avoidance regulations in U.S. and international waters. The black housing provides both corrosion resistance and visual integration with most mast types, while the horizontal mount orientation follows USCG navigation light standards for masthead positioning. The compact footprint—measuring 5 inches by 4 inches by 8 inches and weighing just 2.35 pounds—minimizes windage and structural load on mast extrusions, a practical consideration for cruising sailors and offshore anglers who monitor weight aloft carefully. LED technology delivers extended operational life and lower power draw compared to incandescent navigation lights, reducing battery demand on extended passages.

This light addresses the needs of boat owners who prioritize reliable night navigation without complex installation or maintenance routines. Weekend fishermen running coastal routes benefit from straightforward mounting and proven visibility. Serious offshore anglers and long-distance cruising sailors depend on masthead lights as a core safety component, making Lopolight's engineering focus on durability and consistent performance essential. The Series 301-011 fits the market segment of boaters who value solid engineering and compact design over surplus features—exactly what Lopolight has delivered since 2004.
