2NM 180 Deg White Nav Light, Boats to 50m, Vert Mt, Silver

What you need to know –
• LED 180 Degree White Light (Half All-Round)
• 2 Nautical Mile visibility, 180° white beam
• Certified for use on all vessels less than 50m (164 ft) in length (Vessels under 12m, 12-20m, and 20-50m)
• Mounts on vertical surfaces
• Machined aluminum housing
• 12V/24V

These "half-round" lights are typically purchased and mounted in pairs. They are designed to be fitted on both sides of a ship's instrument or sail mast to effectively create an all-round light in situations where the mast may otherwise block a portion (greater than the allowed 6°) of the beam of a standard all-round light mounted in the same position.
With proper orientation, maximum separation of the halves (width of mast) is 1 meter.
This light has a visibility range of 2 nautical miles, and is suitable for all power and sail vessels less than 164 ft (50m) in length.

These lights feature long service life, rugged aluminum block construction and have an IP68 waterproof rating.

• LED (Light Emitting Diode) navigation light
• Half-round style for butting the flat side to a vertical surface – conveniently mounts from front or rear of fixture
• LED is held in a PMMA (acrylic) lens that is the only 100% UV-stable transparent plastic in existence and ensures the light is guided through a precisely defined 112.5° angle
• Rugged and unbreakable – precision CNC-machined anodized 6082 aluminium block housing protects the LED and electronics
• Not sensitive to vibration - no more broken filaments
• No bulb replacement, ever – lasts for approximately 50,000 hours
• Completely waterproof and vibration-proof – interior is fully filled and sealed after initial testing with special silicon-epoxy potting resin
• Waterproof to IP 68+ (submersible to 350m; suitable for submarines)
• Low power consumption – 70% to 90% less than traditional incandescent navigation lights
• Internal electronics provide full required brightness over the entire voltage range (from 10 to 32 volts)
• Fixture diameter is 3-5/8"
• Pre-wired with 8.2 ft (2.5m) marine grade cable • Available option for longer cable lengths by Special Order
• Factory-tested throughout the manufacturing process
• In compliance with the following standard(s) – COLREG72/ EN14744 / IEC 60945 / USCG (UL1104)
• 5-year limited warranty

To ensure that the light has the required intensity/visibility, each Lopo navigation light includes a microprocessor-controlled flashing signal. The micro-processor keeps track of how many hours the LED has been in use. When the light is first turned on, the signal flashes a code indicating either normal functioning, nearing end of service life, or 50,000 hours of use accomplished - time to replace. (50,000 hours is equivalent to over 4,000 twelve-hour nights.)
