CHAPTER I
INTRODUCTION
Section l. GENERAL
These instructions are issued in order to assist the photographer in
the use of the Photogenic Little Giant Speedspot and Speed Backlite.
These lights were designed to fulfill the needs of the photographic
studio for highly efficient auxiliary speedlights which are small in
size and yet produce the necessary illumination to use in conjunction
with larger hieh voltage electronic flash equipment.
Recent developments have made it possible to pnrduce this equip-
rnent through the use of smaller flashtubes. There is really no essential
difference between the Little Giant series speedlights and those
previously produced. Ilowever, the small size flashtube will not permit
the use of the higher voltage (2000 volts) circuits and nrust operate
at 450 volts. It is obvious, therefore, that the higher voltage power
supplies used on prcvlously designed equipment cannot be made inter-
changeable with the Little Giant series speedlights.
The Photogenic Little Giant Speedspot is made in both the boom
type nnodel and the upright stand model and fulfills the need of a small
size spotlight not only for hair liehting, etc., butalso as a main source.
The Photogenic Litrle Giant Speed Backlite provides a small size
light source which may be easily hidden behind the subject for pro-
ducing background illumination. It is provided with wings which are
easily detachable when not required.
Both the Little Giant Speedspot and Speed Backlite will accommodate
the same snoots as are used on the Photogenic No. ?200 Little Giant
Incande scent Spotlight.
Power supplies are availablein 100 watt-second and 200 watt-second
capacity. Each power supply is provided with a high-low switch so
that the 200 watt-second rnodel may be operated at 100 watt-seconds
and the 100 watt-second model may be operated at 50 watt-seconds.

any further tilt.
3. After the boom arm and swivel are assembled to the stand,
mount the spotlight head on the boom arm. Befor€ connecting the
spotlieht electrically to the power supply, the flashtube and
modeling lamp should be installed in the spotlight head by re-
movins the lens of lhe spotlieht. This is best done by tilting thespotlight upward slightlv before removing the lens retaining iine.
After the lens retaining ring is removed tip the spotlight forward
while holding one hand over the lens opening to catch the lens
as it drops out. The flashtube is polarized so that it cannot be
installed incorrectly. After installing the flashtube and modeling
Iamp replace the lens and lens retaining ring.
4. The spotlieht may now be connected to the power supply and
the line service cord connected to the wall ouilet.
5. If the unit is to be used as a slave unit the No. 929 phototube
shonld be installed in the photoeye socket located on the top of
the power supply. For direct triggering a trigger outlet ls pro-
vided for connecting a trip cord to the camera. The 929 phototube
should be removed from its socket when the trip ccrd is used.

Scc?ion 3. OPERATION OF THE PHOTOGENIC LITTLE GIANT
SPEEDSPOT.
a. Scope. The Photogenic Little Giant Speedspot fills the need
for a snnll, hiehly efficient spotlight to be used in conjunction with
other large source speedlighting equipment in the photographic studio.
It may be used as a hair light or as a main source light in much the
same manner as the Cat. No. ?200 Little Giant Spot which has been
a standard incandescent spotlight used in studios throughout the
counhy for many years. The Cat. No. ?202 snoots and Cat. No. 7206
barn doors are also interchangeable with those used on the Cat. No. 7200 Incande scent Spotlight. I
b. Lens. The 4-L/2" Fresnel Lens prcvides a tight which is con- I
centrated in the center and less intense at the outside edge. This
provides a very efficient main source light for so-called glamour
or butterfly lightings.
c. Power Supply. The power supplies for both the Photogenic Little
Giant Speedspot and Little Giant Speed Backlite are electrically the
sarne. The power may be turned to Hi or Lo by means of a rotary
switch loca0ed in one corner of the power supply (See fig. 5). A separate switch is also provided to control the modeling larnp. When
the unit is on, the red pilot light (power) will come on, showing that
power is flowing into the unit. The white pilot light (flash indicator)
will also glow brightly and gradually dim as the unit reaches full
charge. After each successive flash this light will again glow brightly
if the unit flashe.d. If the unit fails to flash this lieht will not come
on. In this manner it is very simple to determine if one of the units
has failed to flash.
d. Synchronization. The power supply is equlpped with a trip cord
connection (trigger) which may be used to connect the unit to the
camera synchronizer. In addition, the unit may be operated as a slave
unit by installing a No. 929 phototube in the Photoeye socket provided
in the top of lhs power supply. This socket is rotatable so as to take
advantage of the best direction for receiving the light impulse from
another speedlight:
Section 1. OPERATION OF THE PHOTOGENIC LITTLE cIANT
SPEED BACKLITE.
a. Scope. The Photogenic Liftle Giant Speed Backlite provides a
small, very efficient, speedlight source for illuminating backgrounds,
etc. BJ the use of the ba,rn doors and No. 7202 snoots any type of
normal background effect may be obtained.
b. Reflector. The reflector is a 60 degree type reflector which rnakes
it possible to flood the ba0kground if necessary.
c. Power Supply. See Section 3, paragraph c.
d. Synchronization. See Section 3, paragraph d.

Section 5. USE OF BACKLITE WITH BOOM STAND.
Some photographers have found that they wish to dupt the Little
Giant Speed Backlite lighting unit to the Little Giant Boom Speedspot
arm and special adapters are available for this purpose. In this case
the power supply should also be the same type as that used with the
spotlight as it provides for attaching to the stand.
Special Power Supplies with two high voltage outlets are also
available, on special order. These will enable the user to operate
I two liehting units from the same power supply.

CHAPTER III
DETAILS
Section l. POWER SUPPLY.
a. The porver supplies for all units are electrically similar and
provide 450 volts direct current which is stored in the capacitor bank
until flashed through the flashtube of the lighting unit. The 200 watt-
second model power supply is equipped with four 525 Mfd. capacitors
and the 100 rvatt-secord model is equipped with two 525 lvlfd.capacitors.
b. The power source may be any 110 to 120 volt, 60 cycle A.C.
line. By means of a transformer this voltage is increased to 450 peak
volts which is then rectified to direct current and stored in the ca-
pacitor bank until discharged.

c. TTiggering is accornplished electronically by the use of a No.
2D2I Thyratron tube. (See Fig. 5). This tube is easily replaced
by removing the top panel of the power supply. A safety switch is
provided which will completely de-energize the capacitor bank when
this panel is removed. (See Seryice Instructions).
d. The Hi-Lo feature of this unit is accomplished by switching
capacitors in or out of the circuit. When the unit is switched to Lo
position onl.y one half of the capacitor bank is charged, and when
switched to Hi the entire bank is charged. When the unit is switched
from Lo position to Hi position a condition arises in which onehalf of the capacitor bank is fully charged and the other half has
no charge. As this will produce a severe strain upon the switch
contacts it has been necessary to adopt a safety measune to over-
come this. A time interval switch has therefore been provided which
will allow the uncharged portion of the capacitor bank to reach
full charge before being connected directly to the charged portlon.
This time interval is approximately 10 seconds and is automaticallyconhollbd. Therefore, when the unit is switched from Low 0o High
position there will be a ten second interval before capacitors are
ready to be discharged at full power. THE UNIT SHOULD NOT BE
FLASHED DURING THIS INTERVAL.

Seoi5n 2. LITTLE GIANT SPEEDSPOT LIGHTING UNIT
The lighting unit uses a type DXR flashtube and a pHloOTg/lOg
DC Projection Lamp with CC 2V filanrcnt and double contact base. A
cable is provided of proper length to reach the power supply unit when
the stand is fully extended. Flashtubes and modeling lamps may be
changed by removing the Fresnel lens of the spotlight as explained
in Chapter II, Section lc. of this manual. The light may be focused
from spot to flood by turning the knob located at the rear of the housing.
Section 3. LITTLE GIANT SPEEDSPOT STANDS.
All models of the Little Giant Speedspot are provided with air
cushion stands in order to protect the flashtube and modeling lamp
from damage if one of the positioning knobs is accidentally loosened.
The boom type Little Giant Speedsrlot is provided with a boom arm
48" Iong and the following are the limits of the stand uprights:
Lowest Height Extended Height
Nlodels 8200 & 8201 40" 8 ft.
I\l0dels 8205 & 8206 40" I ft.
Scction 4. LITTLE GIANT SPEED BACKLITE LIGHTING UNIT.
a. Reflector and Flashtube. The reflector is a 60 degree type in
which the DXO flashtube is installed as an integral. part at the factory.
If it becomes necessary to replace this flashtube it is best perforrned
at our factory in order to minimize the chance of breakage. The tube
base of the DXo flashtube projects from the lower rear part of the
reflector and must be plugged into the 4 pin socket located on the
socket and cord assembly.
b. Socket and Cord Assembly. The socket and cord assembly is
provided with a modeling lamp socket. In order to change the modeling
lamp it is merely necessary to remove the reflector and flashtube
assembly. A 15 ft. long cable allows the power supply to be locatedaway from the subject where it will not appear in the photograph.Tilting is accomplished through the use of a multiple disc friction
tilting stand adapter.
Section 5. LITTLE GIANT SPEED BACKLITE STAND.
The stand is a telescopic type adjustable from 1g,, to 4 ft. A stand
leg stud is provided to use the light at floor level if rlesired. Arsoa lower level adjustment bracket is available which will provide
adjustment of the light between the floor level and the top of the stand
when it is adjusted to its lowest height.
CAUTION: Whenever it is necessarT to replace flashtubes or modeling
Iamps the unit should be turned off and the lighting unit disconnected
from the power supply.

Section 6. SYNCHRONIZATION.
Syncluonization is extremely important and the greatest care should
be taken in making all connections to the synchronizer cables. If
these connections are not made in a careful and workmanlike manner
it may result in either an intermifrent connection or an electrical leak
between the two leads. Either will cause unreliable perforrnance. An
electrical leak will be especially noticeable during humid weather.
When making any connection to the trip cord the following steps should
be observed:
1. Cut wires of the cables to be connected as shown in fig. 6a.
2. Strip each lead l/2" (Fig. 6a).
3. 1'wist leads together and solder securely. Use only rosin core
solder. Use no flux either paste or liquid. (Fig. 6b).
4. Insulate with Scotch No.33 electrical tape or equivalent. (Fig. 6c).
I il
U a IVG
PREPARATION OF SYNCHRONIZER CABLE
After the synchrcnlzer cable is prrrperly connected lt ls well to
check the synchronization with the camera. Adiust the lighting unit
to the same height as the carnera lens and face the light into the lens.
The lens aperture should be opened to its fullest extent and the camera
back removed. Looking at the lens through the back of the camera,
operate the shutter. The flash of the light shottld then appear as a
circle the same size as the aperture. It is best to perform this test
with modeling lamp turned off. If the circle is flattened on the sides
or if no light appears through the lens, the shutter is not synchronized
with the light. Shutter contacts for this light should be the X or zero
delay type. If the light appears not to be synchronized the shutter
contacts should be checked by a reputable camera repair tnan.

CHAPTER IV
SERVIUE
Section l. GENERAL.
In order that you may expect long and trouble-ftee service every
precaution has been taken in the design and manufacture of this
equiprnent. Frequent servicing is not likely to be necessary and this
chapter is offered to assist the photographer in recognizing the most
probable cause of any difficulty wirich may arise.
While we have gone into considerable detail in service instructions
we assume that, unless you are familiar with electronic equipment,
you will not attempt to make repairs yourself. However, these in-
shuctions will prove of assistance to a competent service man.
Section 2. SAFETY PRECAUTIONS.
a. Despite the extreme measures that have been taken to make this
equipment foolproof, it must be recognized that high voltages do exist
within the power supply,, cables, and lighting units. Therefore, certain
precautions must be observed in handling this equipment.
b. Do not attempt to change tLashtubes or modeling lamps unless
the unit has been discharged and the lightine unit disconnected from
the power supply.
c. Always make certain that the power supply is disconnectecl frorn
the 115 volt A.C. line before attempting to service it.
d. When removing the top lid of the power supply, always assume
that high voltages may exist within. A safety switch has been pro-
vided to discha.rge the capacitor bank when the lid is removed, and
the operation of this switch may result in a loud report. To be doublysafe it is well to connect a rvire betv'reen the positive and negative
terminals of the capacitor bank. This will surely discharge all of
the stored electrical energy.
DO'S AND DON'TS
DO - Turn Power Supply Unit "OFF,' when not in use.
DO - Avoid quick repeated flashing. Damage may result. The full
charging time should be allowed between flashes.
DON'T - Permit a lighting unit cable to become frayed or loose in a
connector.
DON'T - Insert or Relnove a Flashtube unless the power Supply Unitis fully discharged.

www.butkus.us
DO'S AND DON'TS (CONT'D)
DON'T - Remove the top cover from the Power Supply Unit or place
a hand near any part inside the unit until you are certain that the
capacitor bank is fully discharged.
DON'T - Insert a scnew driver or other metal object into the flashtube
socket or any electric outlet, socket or receptacle. Contact with high
voltage may result.
DON'T - Attempt to make repairs to the speedlight outfit if you are not
familiar with electronic equipment. Your dealer should be consulted
rega^rding an authorized electronic or radio service station.
DONT - Use a higher rated fuse than is recommended.
DON'T - Plug the unit lnto any senice except 110-120 V. 60 cycle
A.C. If this unit is plugged into D.C. service it may result in serious
danage to the component parts.
DON'T - Flash unit while the time interval switch ls running.
Scction 3. TROUBLE SHOOTING
&. General. In otder to remedy any difficulW which mieht arise it
is necessary to ipolate the component which is faulty. In order to do
this it must first be rletermined whether the fault lies in the power
supply, lighting unit, or external triggering circuit. vfitn tnis in mind,
when the light fails to flash, the following steps should be taken, in
order, until the difficulty is located:
1. Remove fuse cap to determine if fuse ls blown
2. Disconnect trip cotd from trigger outlet and make contact between
the ccnter terminal and the edge of this outlet. When light is being
used as a slave unit another No.929 phototube should be substituted.
3. Connect another lightine unit to the power supply.
4. Connect another power supply to the lighting unit.
5. Clcnnect another llne service cord to the power supply.
If the above steps are followed the component wherein the fault is
located wlll be isolated.

(1) Repeated flashing as mentioned in D (1) of Section 4.
As a flashtube nears the end of its normal life it may tend to flash
at regular intervals with no apparent reason. This is caused by the
fact that after the tube has been flashed many times, the voltage at
which it may become self conductive decreases. It then will flash
as soon as the voltage reaches this critical point. This condition is
further aggravated by the heat of the modeling lamp. It is also more
likely to occur in equipment which, due to its physical size, cannot
be well ventilated. The life of the flashtubes in some instances may
be prolonged by interchanging tubes between various units. Also, if
the modeling lamp is turned off at intervals it will allow the tube to
cool to a point where it will correct itself. While spontaneous flashing
from this cause is more apt to occur in old hrbes, it may also occur
at times in new ones.
(2) Failure to flash reliably as mentloned in e (3) of Section 4.
Flashhrbes sometimes fail to flash when the modeling lamp has
been turned on for a considerable length of time. This is usually
caused by the triggering Pulse being dissipated through the glass
envelope of the modeling lamp lnto the filament circuit..This occurs
in eqnipment employing the PH60TOy2/l modeling lamp, but not
in spotlights which employ projection lamps. However, it is well to
note whether or not the corrccf modeling lamp ts being used. The
PH60T6/z/1 modeling lamp has a 2" long filament suspended through
the center of the br:lb, and is the successor to the 60T6Yz/I lamp
which had a cluster type filament. This older cluster type filament
modeling lamp caused a great deal more of this difficulty than the
present one. However occasionally the newer type will also cause
trouble when the filament sags toward one side of the bulb, and in
this case it can sometimes be corrected by reversing the modeling
lamp in its socket.
(3) Static Electricity
When elechonic flash equipment is used in a carpeted studio it
will sometimes be noted that the lights will flash whenever they are
touctred. This is due to the fact that when a person walks across a
carpet his body will accumulate a cha.rge of static electricity. Upon
touching the lamp or camera some of this static electricity may be
discharged, causing the lamp to be triggered. This of course is annoying
but it is neither dangerous nor harmful either to the person or the
lighting equipment. The condition is usually apparent during thewinter months when the humidity is low and may sometimes be cor-rected by the use of a humidifier to introduce additional humidity
into the mom.
(4) Modeling Lamp prematurely burns out.
This is usually an indication that the line voltage is considerably
higher than the normal 115 volts. This condition may be corrected by
using a voltage regulator. An automatic voltage regulator should not
be used as it is not applicable to electronic flash equipment. A manual
20View original page 18Page 19 · Read text
type voltage regulator should be used. However it is necessary to use
a regulator equipped lvith a voltmeter,, such as the No. T1404v voltrol
unit supplied by Photogenic Iflachine company and available through
the dealer from whom you purchased this equipment.
(5) iti-Lo Switch.
As mentioned earlier in these inshuctions, when the unit is switched
from Lo to Hi an interval of 10 seconds should be allowed before
flashing. If flashed drring this period it may result in damage to theswitch contacts as it may cause the timer srvitch contacts to stick.
If this o@urs damage will then result to the main switch and a report
may be heard during switching. If the main switch is damaged it nray also result in the unit producing the same output on low as it does
on high.
(6) CAUTION.
It must be rcmembered that all electric flash equipment uses voltages
whiclt are dangerous. AII Photogenic Speedlights are carefully designed
to be safe when used in accordance with the instructions. If you a^renot fully familiar with electronic equipment, it is essential that you
contact an authorized service man or your dealer if service is nec-
essary, calling his attention to these instructions.
(7) FactorJ Repair.
If at any time this equlpment fails to operate properly and you, or
your service man, a^re unable to determine the cause, The photogenic
Machine comparly maintains a repair department which is equipped to give fast, competent service.
When it is necessary to return any equipnrent to the factory for
service it should be accompanied by a complete explanation of thedifficulty which exists. This will greatly assist our repair department
in expediting the return of your equipment.
If argr doubt exists as to whether the power supply or the lighting
unit is defective, both should be returned.
