Pharos Marine Automatic Power FA-250 Marine Lantern

The Pharos Marine Automatic Power FA-250 Marine Lantern is a professional-grade long-range marine navigation lantern used on lighthouses, offshore platforms, harbor beacons, jetties, and fixed aids-to-navigation (AtoN). It is one of the better-known lantern platforms in the commercial marine signaling industry because of its modular design, high optical efficiency, and durability in harsh saltwater environments.

Features

4- or 6- place motor driven, APCL-5/APCL-10 Flashchanger with selectable flash rhythms, pulse width modulation regulation, solar charge regulator, monitoring, synchronization, self-test function, communications port, lamp-out control terminal, photocell and enhanced environmental protection
Precision-molded acrylic Fresnel lens that has better optical characteristics and higher transmission than glass and longer-term dimensional stability than cut acrylic: light weight and its color filter transmission is typically 25% higher than glass
Smooth, protective acrylic lens cover eliminates the buildup of fillets of moisture, dust, salt spray, raindrops and other contaminants on the internal Fresnel lens prisms.
Can be simply and inexpensively converted to a different color to colored sectors
It exists in several versions: Incandescent, LED Medium Range, LED Long Range FA-250 & Explosion-proof FA-250EX for offshore oil and gas environments
The classic incandescent version typically provides: 4–20 nautical mile nominal range at T=0.74 meteorological visibility
The newer LED Long Range version can exceed:18 NM at T=0.74 & 28 NM at T=0.85 under some configurations
Has the widest vertical divergence of the long-range omnidirectional signaling lanterns
Complies with the traditional IALA minimum vertical divergence of 2.5 degree and the FAA minimum vertical divergence of 3.0 degree
