Lowel i & id-light Instructions

Warnings

The Lowel i & id-lights are profession­al DC powered lighting fixtures.
Read these instructions and lamp man­ufacturer’s warnings before operating.

n Not for house hold use, use only

for film, video or imaging purposes.

n The units use lamps of several

different voltages. Make certain that power
source voltage matches lamp voltage.

Example: never connect a 12 volt lamp
to a 30 volt source.

n Do not use near standing water,

or in rain.

n Units such as this emit

considerable light and heat, and if not
properly used, could be dangerous.

n Lights should not be positioned

extremely close to people. Ultraviolet light ray
emissions can cause damage to the eyes and
reddening of the skin. The likelihood of either
occurring is increased with length of expo­sure, focus intensity and proximity. Therefore,
lights should be kept away from people.

n Avoid aiming the light at, or placing

too close to, people, delicate objects or
flammable materials.

n Do not interfere with ventilation

by covering the lights in any way.

n For proper ventilation, do not tilt

down beyond 45 degrees or operate sideways.

i & id Lamp Replacement

1 Turn focusing knob A to spot position.
2 Unscrew the small knob B located on top

of the front reflector assembly. Remove
front assembly by tilting “downward”.

3 Holding the focus knob in spot position

grasp the rear metal portion of the lamp C
and push in.

4 This will release the two “dimple” studs D

which seat the lamp in its socket.

5 While continuing to push the lamp

assembly E in, gently slide it upwards
and out of the socket. Slowly pull the
lamp forward slightly. This will expose
a single-wire connector F.

6 Separate the lamp from the single-wire

connector. Make sure single-wire
connector does not fall back into the
lamp housing.

7 Connect this wire to the replacement

lamp. Align connected lamp with the
flat side of the metal lamp base facing
down (the 4 o'clock position).

8 While pushing in, gently slide the lamp

downwards until the two “dimple” studs
are seated in the socket.

9 Replace the front reflector assembly

and tighten the top knob.

i & id- lights are supplied with the
iP #2 Reflector

This computer designed, faceted high intensi­ty reflector gives improved light output. It can
be used with either the supplied Prismatic
Glass (focusing) or Clear Safety Glass (high
intensity non-focusing super-spot only).

Never operate Pro or i / id-lights without pris­matic or safety glass installed.

Pro & i / id Focusing and
Focus Knob Extension

Code: iP-35

Turning focusing knob, located on the side
of the housing, alters

the beam of light
from flood to spot. A
focus knob extension
accessory snaps into
focus knob for left-hand
or on-camera focusing.

Compact filament lamps may fail if subjected
to shock or vibration while on. Operating the
focus smoothly will help prevent lamp failure.

i & id-lights have
a Universal Mounting Bracket

mounting of i / id & other ViP Lights
to stands and accepts several light control
accessories.

Barndoor Frame

Code: iP-21

Accepts swing-in accessories, and/or leaves.
Rotates 360°.

Attaching the Barndoor Frame

to the front of the light with and without
barndoors.

1 Loosen the knob A on the Barndoor

Frame.

2 Set the frame clamp retaining feet B into

the first ventilation groove C of the light.

3 Tighten knob. Proper installation allows

full 360-degree rotation of the complete
barndoor assembly.

Attaching the leaves to
the Barndoor

A

Expandable Leaves and Nonexpandable
barndoors are attached to the frame by con­stant-tension lock fasteners A located on the
rear of the doors. The lock fasteners require
a 1/2 (180-degree) turn to remove or install
the barndoors. Lock fasteners should be on
the “inside” of the barndoor flap, It is possible
to install a barndoor leaf backwards so that
it will not close over the light. It is important
to align the barndoor leaf to the frame.

2-way Barndoor

Code: CL-15

Swing-in
Accessory
Holder

Holds Light Control
Accessories, attaches to the Barndoor Frame in
a similar manner as the barndoor leaf. Align
Accessory Holder on Barndoor Frame. The
lock fastener requires a 1/2 (180-degree) turn
to remove or install the
Accessory Holder. When
in use, Accessory
Holder
swings over
the light and
locks onto the other
side of the frame. Three holders
can be attached to the Barndoor
Frame simultaneously, but only one can be
used at a time. A full barndoor set and a single
holder can be used at once. Quickly swinging
one holder out of position and swinging in
another is a valuable user convenience.

Code: iP-30

Changing Light Control
Accessories

Simply release the captive retaining spring clip
located inside the Holder and remove accesso­ry. Insert new accessory and secure retaining
spring clip. A scrim and glass accessory may
be mounted together in a single Accessory
Holder. Separate holders for each accessory
are recommended for fast in-use changes.

Swing-in Accessories

Diffused Glass

softens highlights and shadows.
Absorbs U.V. Iight rays Light loss
approximately 40%.

iP Prismatic Glass

Code: iP-52

Supplied with all Pro & i-lights.
Gives an evenly dispersed flood,
produces a more uniform spot and
a fresnel-like barndoor cut. When
used in holder with Clear Safety
Glass (iP-49) installed in front
housing, allows focusing use when
swung in & super spot use when
swung out.

Full Scrim

reduces light by approximately
one stop.

Half Scrim

covers half of reflector and rotates
360° darkens washed out
foregrounds, compensates for
actors “burning up” as they
approach a light.

Graduated Scrim

Code: iP-56

same principle as half scrim
but effect is more gradual
and more extreme.

Snoot

as does a Barndoor Frame. iP
Snoots can be “piggy-backed.”

Code: iP-54

Code: iP-55

Code: iP-53

Produces a reduced circle of
light; Barndoors and barn­door accessories may also be
added to the end of the
Snoot. A Snoot attaches to
the light in the same manner

Pro & i Gel Frame

Code: iP-40

Holds 5 x 6" gels.
Unfold frame,
extending frame bar and
insert through front slot of
UMB Lock with knob. Pans and tilts with the
light, collapses for storage.

Pro & i Gels

Size: 5 x 6" (12.52 x 15.25 cm) sheets

Tota-brella

Photographic umbrellas
convert relatively hard light sources,
such as spotlights, into relatively soft sources
that provide soft shadows and highlights.
Although not appropriate for every subject
or mood, the quality of light can be very
beautiful. There are two umbrellas suitable
for use with the i & id lights:

Silver (Code: T1-25), reflective umbrella.
White (Code: T1-26), a white nylon

umbrella that produces a softer light and also
may be used as a large diffuser. To mount
umbrella insert umbrella shaft through round
hole in UMB and lock with knob. Tota-brella
and Tota-frame cannot be used simultan­eously.
Warning - When lights with umbrellas are
extended very high, or used on undersized
stands or in areas of heavy “traffic”, it is
advisable to add weight (such as the Lowel
weight) to the base of the stand to reduce the
chance of lights falling over which could
damage the umbrella, the lamp and possibly
cause personal injury.
Warning - To prevent possible umbrella
damage, avoid full or near-full spot reflector
settings on the i or id-light and do not use
with a Clear Glass as Super-spot.
