4. Materials and Manufacture
4.1 Material:
4.1.1 All materials used in the construction of these searchlights shall be of a quality suitable for the purpose intended and shall
conform to the requirements of this specification.
4.1.2 The searchlight shall be constructed of brass, copper-alloy, an equivalent corrosion-resistant material, or a material that
when tested in accordance with Practice B117 for 200 h, does not show signs of pitting, cracking, or deterioration.
4.1.3 Plastic, when used, shall be of a suitable thermoplastic or thermosetting material so molded as to produce a dense solid
structure, uniform in texture, finish, and mechanical properties.
5. Requirements
5.1 The height of the searchlight from the base to the top of the light shall not exceed 19 in. (483 mm).
5.2 The housing of the searchlight shall be capable of free movement of at least 60° above and 45° below the horizontal, and
be able to rotate 360° in the horizontal plane. There shall be a means provided to lock the searchlight in any desired position
without the use of tools (vertically and horizontally).
5.3 The searchlight shall be capable of illuminating a light colored object at night at 55 ft (16.8 m). The searchlight shall project
a beam of light of not less than 5.5 ft (1.68 m) in diameter at a distance of 55 ft from the light source. The edge of the beam shall
be a point where the intensity of the light is 10 % of the maximum intensity. The light source shall have a candlepower rating of
no less than 350,000 350 000 cd.
5.4 The searchlight shall be capable of being operated for not less than 3 h of continuous use and 6 h of intermittent use.
5.5 The lamp used in the searchlight shall be of the incandescent, quartz, or other type which would allow for instant start. The
lamps shall be rated for 12 V.
5.6 Each searchlight shall be watertight. The searchlight shall show no leakage of water following the test method prescribed
in 7.1.
5.7 Each searchlight shall be wired with a 6-ft (2-m) length of rubber jacketed hard service flexible cord, unless otherwise
specified in 8.3. The conductor size shall be no less than 16 AWG. The cable entry into the searchlight shall be sealed with a
watertight bushing and packing gland. A suitable clamping device shall be installed in the area where the cables enter the gland
to prevent any force being exerted on the gland or connections. The free end of this cord shall be dead-ended unless otherwise
specified in 8.3.
5.8 Each searchlight shall be provided with a handle or handgrip to allow for ease of maneuvering the light into various
positions.
5.9 Each searchlight shall be operated by a contact switch which allows the searchlight to be off, steady on, or in flashing mode
(if provided).
6. Workmanship, Finish, and Appearance
6.1 Searchlights shall be of sturdy construction, and free from mechanical, electrical, or other imperfections or defects which
materially affect appearance or which may affect quality, reliability, or serviceability.
6.2 The finished searchlight shall not contain rough edges, burrs, or other disfigurations and shall be clean, free from rust, tool
marks, and other injurious defects.
7. Test Methods
7.1 Watertightness—The searchlight shall be submerged in a 60°F (16°C) saltwater solution (1.04 sp gr) to a depth of 3 ft (0.9
m) for 2 h. The light will then be subjected t
