Lamp Switches
There are 4 lamp switches A,
each controlling a pair of lamps.
By turning one or more pairs of lamps
off, you can vary the output of the light.
Remember that there is also a master
power switch in the supplied
AC Cable.
Fuse Replacement
To open the fuse cover B, first make
sure that power has been disconnected
to the fixture. Use a small flathead
screwdriver to remove and replace fuse
if needed.
Rear Panel
■Loosen the side yoke locking
handle so that the yoke can be easily
positioned out of the way for the
following procedure.
■Place the fixture on its 4
small support feet so that the sockets
face up, making sure that the AC Cable
is not connected.
■Gently snap the 8 fluorescent
lamps into the cluster of sockets on
the front of the fixture. Start with the
center lamps.
Note: The procedure is the same
whether installing 12" or 8" lamps.
■Position the Polycarbonite
Lamp Shield over the installed lamps
so that the holes in the metal plate end
of the shield line up with the ends of
the lamps.
■Gently slide the shield down
over the lamps until it completely
covers the lamps. Carefully tighten the
2 nylon Locking Nuts Aon the front of
the shield. This tightens the threaded
ends of the shafts at the fixture body
to securely hold the shield and lamps
in place.
■The AC power cord attaches to the
socket on the rear panel and contains a
master power switch.

Film Use
If using Scandles with conventional film, initial experiments suggest a minus 1/4
or 1/2 green filtration for film exposures.

Mounting
on stand
■Holding the fixture
with lamps & shield
installed, carefully position the
stand fitting end of the yoke arm
on the 5/8" stud of the stand.
■Tighten the locking arm to
prevent the light from falling
forward. Make sure to align one
of the stand legs directly underneath
the lamps for best stability. Add
weights to the stand base for safety if
needed.
■Recommended Lowel Stands:
KS or larger for best stability,
however Uni Sr., and KS Jr. can
be used for more portability.
Mounting on boom
■Rotate the yoke counter-clockwise
to position it for attachment to a 5/8"
stud on the end of a boom using either
of the stand fitting holes. Experiment to
find the position that best suits your
purpose.

Attaching
Accessories
The LowelScandles light has a number
of front attachment accessories which
can be used to help vary the output
and quality of the light. They attach to
the installed Universal Rotating Speed
Ring, either by using the 4 retaining
screws on the front of the ring, or the 6
softbox mounting holes on the side of
the ring. In addition, there are 2 screw
threaded holes on the side of the ring
(1/4-20, and 3/8-16) for additional
options).

Mounting Yoke
The yoke of the LowelScandles
light is designed to allow maxi-
mum versatility when mounting
the fixture.
■The yoke can rotate approximately
300 degrees, and has 2 additional 5/8"
stud mounting holes, allowing it to
attach from different angles.
■The yoke arm also has a hole for
attaching safety cables which must be
used whenever hanging the fixture
from boom or rail.
■The locking handle can be loos-
ened to allow the fixture to slide back
& forth. This is useful to reposition the
light’s center of gravity, making it more
stable on the stand, especially when
attaching front accessories which can
cause the balance to shift.
■Whenever mounting fixture over-
head, always attach safety cables
between the fixture and the rail using
the hole in the yoke.

Collapsible Cone &
Front Diffuser
■The sections of the cone are
made of clear plastic and come with
installed reflective material, which
should be suitable for most lighting
purposes. Each section opens to allow
color gels, diffusion or other reflective
materials to be used for special pur-
pose lighting effects.
■Assemble the Collapsible Cone
by zipping the 3 sections together.
■Attach the narrow end
of the cone to the Mounting Ring by
lining up the 3 snaps.
■To attach the cone & ring
to the front of the rotating speed ring,
place the fixture with lamps & shield
installed on a table, facing up so that
it rests on its 4 rear panel support
feet, or securely on a stand, facing
straight up.
■Remove the 4 plastic retaining
nuts from the screw posts on the speed
ring and carefully place the cone over
the lamps so that its metal ring rests in
the recess of the ring. Replace the 4
plastic nuts and tighten securely.
If you want additional softness, attach
the front diffuser to the front of the
cone reflector by collapsing the cone
slightly to get the elastic of the diffuser
over it. Note: diffuser reduces output
by approximately 50%.
Hard Cone Reflector
■The Hard Cone Reflector
is designed for studio use. It is not
collapsible. Attach the Hard Cone
Reflector using the same procedure
as the Collapsible Cone.
■Place the fixture, with lamps
& shield installed, on a table facing
up so that it rests on its 4 rear panel
support feet.
■Remove the 4 plastic retaining
nuts from the screw posts on the speed
ring and carefully slide the reflector
over the lamps so that its metal ring
rests in the recess of the ring.
■Replace the 4 plastic nuts and
tighten securely. You can attach the
Lowel Fin-S clip adjustable barndoor
to the rim of the reflector for additional
light control.
