In the 2010s, LED lamps began replacing incandescent lamps in lighthouse applications, [4] so it seems likely the twenty year replacement will use an LED light source. In fact, several VLB-44 LED beacons, [5] also made by Vega Industries, have been installed by the USCG at several locations, including White Island Light [4] and Wood Island Light. [6]
The rotating beacon 24 inch (610 mm) parabolic mirror and a 110-volt, 1 kilowatt lamp. [ 11 ] spinning at 6 rpm, creating a quick one-tenth second flash every ten seconds. In clear weather they could be seen for 40 miles (64 km).
DCB-224 - Two Harbors Light. The model DCB-224 is a high-power spotlight designed and built by Carlisle & Finch. [1] Originally intended for use as an aerodrome beacon, it was also widely used in marine lighthouses. Depending on the type of bulb installed, the beam could be seen for 18 to 26 nautical miles (33 to 48 km).

These project a narrow light beam. The light rotates, causing it to appear to flash from the viewpoint of a distant observer. These were originally used as aerodrome beacons, but in the 1990s, the U.S. Coast Guard adopted them for use in lighthouses, replacing existing Fresnel lenses. Models included DCB-24 with a 24-inch (61 cm) diameter, DCB ...
