manually operated. If used in an emergency, the
manually operated hand lanterns should ALWAYS
BE RETURNED TO THEIR ORIGINAL
LOCATION.
SEALED-BEAM LIGHTS
Sealed-beam lights are a type of flood lantern
(fig. 12-11, view C). These lanterns are used to
give high-intensity illumination in damage control
or other emergency repair work. These units
consist of a sealed-beam light similar to that
used for automobiles. The sealed-beam light,
powered by four small wet-cell storage batteries,
is mounted in the battery case and fitted with a
handle for convenient carrying. A sealed-beam
lamp will operate for 3 hours before the batteries
require recharging. When the batteries are at full
charge, the beam has an intensity similar to that
of the headlight on an automobile. At the end of
3 hours, the light output will gradually drop to
about one-half its original brilliance. These sealed-
beam lights are normally stored in the damage
control repair lockers.
