ULTRALIGHT CAP LAMP SYSTEM

The Ultralight headpiece is made up of
the lamp-housing, which contains the
following parts:
— Bezel (cover);
— O-ring
— Main bulb and reflector assembly
— Spring
— secondary bulb
— 3-position switch
— Printed circuit board
— Charging key system

Bulbs are tungsten-halogen type con-
struction.

The main bulb is mounted in the
reflector, positioned for a tightly-
focused beam at maximum light out-
put, and then bulb and reflector are
cemented together. The main bulb
and reflector are held in the lamp-
housing by the bulb pins, which plug
into a flexible circuit board.

The secondary bulb gives enough light
for the wearer to leave the mine if the
bulb burns out. This bulb also plugs into
the lamp-housing circuit board, but
passes through the reflector. Since the
bulb is not centered in the reflector, it
does not give a bright, sharp spot.

The spring keeps the reflector tight
against the cover bezel. An O-ring,
mounted in a groove in the lamp-
housing, seals against the bezel to

help keep out dirt and moisture. A
stainless steel clip holds the head-
piece firmly to the miner’s cap. A
durable, abrasion-resistant cable con-
nects the headpiece to the battery and
allows freedom of movement.

Using the Ultralight Cap Lamp
System
The on-off switch is a 3-position switch,
located on the headpiece. The center
position is OFF. To operate the lamp:
1. Place the switch forward all the

way to light the primary bulb. 

This bulb forms a tight spot for
maximum lighting.

2. Push the switch to the center posi-

tion to the lamp off.

3. Push the switch back all the way to

light the secondary bulb. 
This bulb will not form a tight spot,
but will give enough light to leave
the mine.

If the main bulb fails to light, turn
the secondary light on, and immedi-
ately go to a well-lit area and
replace the main bulb.

MAINTENANCE OF THE
ULTRALIGHT CAP LAMP SYSTEM

HEADPIECE ASSEMBLY

Removing the Bezel (cover)
P/N 476705
1. Use a 3/32” allen wrench to thread

the two allen set screws
(P/N 634639) into the lamp-hous-
ing (P/N 486610).

Note

It is easier to remove the bezel by thread-
ing the set screws into the lamp-housing
rather than out of the lamp-housing.

2. Pull the bezel off the lamp-housing.
