n Unplug before cleaning
material. Handle reflector with care.
Clean with a damp cloth only,
as soap or chemical cleaners may
damage material. Do not operate
while fixture is damp.
n Do not fold Diffuser when
storing. Roll it up onto supplied
cardboard tube to prevent cracking.
Lamp Warnings

it to cool before lamping,
changing lampheads, storing.

Lowel Rifa®eXchange®Instructions
Setting up Rifa eX
Warning: Do not pull power cable to open light. Doing so may dam-
age the cable & fixture. Make sure fixture is unplugged before setup.
n Remove the Rifa eX unit
from its sleeve and mount and
lock on suitable stand.
n Release tilt lock handle,
tilt light to horizontal, relock
tilt handle, release the Velcro
strap around the folded
assembly.
n Reaffix the strap to itself.
Unfurl Rifa-lite reflector material until assembly loosens.
n Loosen thumbscrew located on back end of fixture.
n While holding the assembly base push the socket/lamp
cage assembly (avoid touching lamp) inward until the
assembly “click-locks”
into position.
n Tighten thumbscrew clockwise to lock fixture open.
Warning: The fixture must
be locked open before using,
failure to do so may cause the
fixture to close during operation, damaging the fixture.
Note: Make sure tilt lock
handle is on left side when
viewed from rear, this will
cause lock to tighten if light
droops forward on stand.
n Orient on stand with one
leg extending straight out
under Rifa for best balance.
n For increased balance, use
Rifa Balance Bar accessory.
n Attach diffuser panel by
placing it over the front of the
light inserting the corner pins
of the reflector frame through
the grommets of the diffuser,
securing it with Velcro strips
located around the reflector.
n Never use more than one
diffuser at a time.
Always operate Rifa-lite
with diffuser panel in
place.
n Attach 16' extending
(switched) power cord to
captive cable IEC connector.

Attaching Soft Egg Crates Packing & Storing Rifa eX
Soft Fabric Egg Crates
are a valuable accessory
for controlling the aproximately 80˚beam angle
of Rifa, which can cause
unintended light spill in
other areas of your shot.
They can also help prevent a moving subject from becoming overlit
as they approach the light. Egg Crates are
available in 3 different dispersion angles (30,
40 & 50 degree) for each model of Rifa. Egg
Crates will lower output of Rifa eX.
n 1 Unfold Egg Crate accessory. With the
diffuser already attached, place the Soft Egg
Crate over the front of the light, inserting the
corner pins of the reflector frame into the metal
tube sockets located in the egg crate corners.
n 2 Secure the egg crate to the body of the
Rifa with Velcro strips located around the edge
of the reflector housing.
12
Unplug light and allow to cool for at least five minutes before disassembly.
n Detach Soft Egg Crate (if used)
and front diffuser. To prevent damage to the
diffuser, wrap material around tube and place
in pocket of light storage sleeve.
n Accessory flourescent lampheads & lamps
will prevent Rifa eX from collapsing fully.
Remove lamps and head before collapsing.
Place supplied protective caps on head & post.
