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.

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
Barndoor Frame with two removable non­expandable leaves. Frame accepts swing-in accessories and additional leaves. Rotates 360°.

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.

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.

Stands
The i & id-lights will lock onto stands with top studs up to 5/8” (16mm). We recommend the Uni-stand or Uni TO Stand, for most applications. Where elevation greater than 7’ 9” is required, we recommend Lowel KS stands with Half or Full Poles. i or id-lights can be positioned low on any stand with a Tota-clamp. Lowel-weights add to stand sta­bility and should be used when appropriate.
Uni-stand
Code: UN-33 Size: 21.5"
(54.6 cm) folded. Extends to 7'11" All aluminum stand, wide base, legs can lie flat to floor, large locking knobs. Folds compactly to fit in smaller kits.
Uni TO Stand
Code: UN-55 Size: 21.5" (54.6 cm)
folded.
Maximum height:
7'11" (2.4 m) Base diameter: 43" New stand, based on design combination of Uni-stand & Omni-stand. More stable than Uni-stand, more compact than Omni Stand.
Vipod & Stud-link
Code: ViP-35S
Supports i / id or other ViP Lights on flat surfaces. Vipod can be screwed, Gaffer-taped or clamped to vertical sur­faces. Stud-link is remov­able. The Low Link can also be mounted on the Vipod by attaching the Low link to the Vipod using the knob provided with the Lowel link.
Tota-mount
Code: T1-32
Tota-mount supports any of the ViP fixtures atop doors and parti­tions. Doors can be open or closed.The light can be inside or outside room, since swinging arm extends past most door jambs. Tota-mount can be flipped over and nailed to studio set walls or Gaffer-taped to windows or tile, wood, metal and other wall surfaces.
Mounting Tota-mount & Vipod with Gaffer Tape
Use 12”of Gaffer-tape on each bar on Tota Mount or side of Vipod and burnish down with a coin. Avoid wallpaper,
Lowel i & id-light Instructions
soft composition board or flaking paint. Never attach to the ceiling with tape. Use original Lowel Gaffer-tape. Many substitutes leave adhesive residue or lack sufficient strength. When properly attached, Tota-mount or Vipod will support the Iight for days. However, on dirty or poorly bonded surfaces, or with improper or poorly applied tape, there is the danger of the mount falling down and causing serious damage. Check adhesion periodically. Prevent direct light from overheating tape. Remove tape when cool, by peeling back diagonally. Tota-mount should not be used with lights heavier than 3 lbs. (1.33 kg)
Tota-clamp
Code: T1-30
Tota-clamp supports most lights that fit standard 5/8” studs. Tota-clamp can be attached to pipes, stands, or flat surfaces. When clamping on furniture, use thin wood or cardboard to avoid marring. To rotate stud, turn wing nut counterclockwise several turns. The stud can be locked in any of four positions; two for the 5/8” stud and two for the end with the 1/4-20 tapped hole. A 1/4-20 screw can be used to lock on some micro­phone yokes and various accessories. Tota-clamp has two snap-in fittings for Flexi-shafts.

Lowel i & id-light Instructions
& id-light for the New Professional
i
Use the i & id-light as a convienent, lightweight, DC powered source for a flexible key, fill or back-light that goes places that the AC cable can’t. Adding accessories will extend your creative possibilities.
id-light notes:
When using the id-light, keep in mind that its lamp will shift its color temperature warmer as the light is dimmed. If you find a particular dimmer setting that you use most often, store a white balance in your camera with the light at that dimmer setting. Then use a grease pencil to place a mark on the body of the light that lines up with the white line on the dimming control. In the future, you can return to that dimmer setting quickly and have a prestored white balance for it in the camera.
Use the focusing knob
to move from Spot (narrow beam) to Flood (wide beam). Its 5:1 focus ratio (when used with a i-100 lamp) means that the spot setting will be approximately 5 times as bright as the flood setting (at full brightness for id).
The i & id have a high intensity reflector & prismatic glass installed. This combination gives an even output with
a fresnel like quality in the shadows, an evenly dispersed flood, and a uniform spot with significant barndoor cut. It is capable of throwing sharper shadows when used on its own. Add a diffu­sion glass swing-in accessory, diffusion gel with a gel-frame, or attach an umbrella to create a softer source.
Because the i & id-lights are tungsten-halogen sources, their color temperature will be aprox 3200°K (at full
brightness for id), To use the light in locations where its output will mix with daylight (5600–6500°K ), its color temperature can be converted by attaching a Dichroic Filter swing-in acces­sory, or adding day blue gels to the Pro & i gel-frame. Both will give more realistic daylight white-balancing in video or film. Using gels will give more versatility since they are avail­able in 1/2 & 1/4 strengths of full blue. Note: adding day blue
gels or dichroic filters will reduce output.
Swap the Prismatic Glass to Clear Safety Glass for non-focusing higher output Super-Spot. This can be useful when lighting a small area from a greater distance, where higher output is needed. For faster switching on location, try using Clear Safety Glass in the front housing & placing the Prismatic Glass in a swing in accessory holder. Use the light for normal focusing with the accessory swung in, and then swing it out of the way for quick switch to super spot.
For more reduced spill, consider adding a Snoot.
Other front accessories can help vary the quality of the light output. For example, the rotating half-scrim can
allow you to reduce light output on a close subject while still illuminating subjects further away with full output. The full scrim reduces output without the use of a dimmer which can shift the color temperature warmer as the lamp is dimmed.
The oversimplified diagram below shows some of the ramifications of positioning lights for different subject types & lighting effects. This diagram is only useful as a start­ing point for new pros. All subjects & scenes are dif­ferent and make different demands upon lighting. The height of the lights & camera, and the subjects angles & reflec­tivity must be considered.
Note: in stationary use with battery belt, plac­ing belt around stand bottom adds ballast to help prevent accidental tip-over.
Use the rotating barndoors to trim unwanted output spill, (for example: to reduce risk of shadow in your shot caused by use of overhead boom microphones). Flexi-shafts & Tota-flags can also be attached for increased light control options.
