1-51. LIGHTING SYSTEMS.
a. Most lighting equipment aboard ship consists of standard Navy lighting fixtures and fittings.
In some places,
commercial marine fixtures have been used.
b. All the interior, above deck compartment lighting and crew quarters lighting aboard the vessel is darkened ship
controlled. The lighting circuit breakers in the distribution panels are marked "DARK SHIP" to allow these circuits to be
opened. Also, two door switches are provided to turn off deckhouse lighting (except Pilothouse) if the deckhouse hatch
or galley-to-pilothouse doors are opened.
c. Relay type hand lanterns and portable hand lanterns without relay are set up below deck to provide light in
compartments if other lights fail. Lanterns are placed to light up access hatch spaces and important work areas. Five
portable (Red) hand lanterns can be found above deck in the deckhouse space for use in an emergency.
d. A 12-inch signaling searchlight is mounted on a single post stand on top of the deckhouse. The searchlight housing
is yoke mounted to allow full rotation. It also allows elevations from 45 degrees below to 105 degrees above the
horizontal. The lamp rating is 1000 watts.
e. Three 300-watt Floodlights are mounted along the inboard side of the deckhouse topside. Each floodlight can be
turned and/or tilted to light up the vehicle deck area. The light switches are found close to the lights.
f. Local lighting is controlled from local switches. Navigation lights are all controlled and supplied from the navigation
light panel in the Pilothouse. The Navigation Light Panel is supplied 120- volts AC from the L-106 Distribution Panel.
