Your Sun-Lite II Portable Speed Flash is a scientific.
ally engineered, precision-built electronic flash unit that
utilizes the most advanced research in the electronic flash
field. It combines the new high efficiency voltage-doubling
circuit developed by the National Carbon Company with
the latest developments in eleetrolytic condensers, flash
tubes, and reflectors, to give a flash unit with professional
performance at a price within the reach of the average
amateur photographer.
The Sun-Lite II is so simple in construction and design
that practically nothing can interfere with its perfect
operation. In addition, it is so simple to operate that
anyone can use it. It's simple, fool.proof and safe.
All component parts are carefully selected and indi-
vidually tested. Workmanship is of the highest quality.
Every Sun-Lite unit must pass the strictest quallty stand-
ards, and is UNCONDITIONALLY GUARANTEED for
one year!
Your Sun-Lite II is mcehanically rugged, but like any
electronic instrument, it should have proper care in
handiing. With such care, it will give you years of de-
pendable service. Read this manual carefully. Get to
know your Sun-Lite thoroughly and it will provide the
good results you expeit.

There are three basic Sun-Lite II units that differ only in their inter-
changeable power sources. All of them have the same Flash Head, which,
since it contains its own storage condensers that determine the light out'
put, gives equally excellent results in all three versions.

axlen3ion light the f losh heqd
outlet The Flash Head is the heart of the Sun-Lite
II. It contains the condensers that are used in
the flash circuit, the oscillating ready light, an
extension light outlet, and the triggering circuit
for firing the flash tube. It accommodates the
Sunfleetor (combined reflector and flash tube),
which gives you much more light because of its
advanced design. The mounting bracket is a
standard L-shaped bracket complete with three
screws for attaching it to the Flash Head and
your camera. It is covered with sturdy, ribbed
rubber to safeguard your camera from scratches
or mars. The shutter cord which comes packed
separately in the carton consists of a connect-
ing wire with a polarized standard plug on one
end which plugs into the flash head and the
camera fitting that attaches to the shutter on the
other end.
Because the Flash Head contains the storage condensers that are charged
by the power source, Sun-Lite equipment is more versatile than other
makes in which the condensers are located at the power source. As a
result, Extension Lights multiply the light rather than divide it, which
allows you to use as many lights as you wish, gaining light output
proportionately.

model 24o
Like its bie brother, this pack contains
similar components. Its power battery is a 240
volt ff491 Eveready battery which gives maxi-
mum efficiency with minimum size and weight.
The voltage doubler is operated by four Pen-
Lite cells (Eveready battery #915).
To open the pack, follow this simple pro-
cedure: first, place the pack on its side with
the switch towards the top and in the "off'
position; then remove the bottom plate of the
Pocket-Pak by pressing the sliding button catch Bottom Plote toward the center of the plate, disengaging a
small prong which allows the underlying rubber
cushion to push the plate loose. To replace the
bottom plate, engage the fixed lug. on the
bottom plate in the opening at the side of the
case next to the Pen-lite cells and press it down firmly on the sponge
rubber. Then push the sliding button catch so that the little metal tongue
engages in the slot on the opposite side of the case.
the AC odqpter
or poYYer source
This power source consists of a transformer
and rectifiers which convert ordinary ll0 volt
60 cycle AC house current into the equivalent
of the direct current furnished by Sun-Lite
battery packs. While it is an integral part of
the Sun-Lite II AC unit, it is so often used as
an accessory for the battery pack units that it
is called the AC Adapter. The ordinary electric
light plug fits into any household outlet, and
the fitting on the other cable accommodates the
plug of the Flash Head. In using this power
source never plug it into the electric light out-
let until all other connections have been made.
Do not plug into DC current.View original page 6Page 8 · Read text
To test-fire the unit, turn on the power pack switch (or plug the AC
Adapter into the electric light socket) and wait until the ready light
comes on and flickers rapidly. Then short out the fitting which would
normally be attached to your camera with a knife blade or small screr{
driver. This can also be done by unscrewing the outside tip of the
camera fitting on most shutter cords and touching the usually shielded
or o'hot" side of the shutter cord to the grounded metal of your Flash
Head or bracket, which will also fire the flash.
If you receive a slight "tingle" or tiny electric shock by holding the
outside of the shutter cord fitting in one hand and your camera in the
other, or if the light is discharged by touching the outside fitting to the
metal of your Flash Head or camera your shutter cord is wrongly polar-
ized and the plug should be reversed in the Flash Head outlet. The same
is true if the ready light comes on and glows continuously instead of
oscillating.
If yotrr camera has an "X" (zero delay) setting or has provision for
synchronization with electronic flash you are no\,v ready to take pictures.
Simply connect your shutter cord to your shutter and you are all set to go.
A Word of Cqutio'n. The Hershey Manufacturing Co., has taken
every possible precaution to make Sun-Lite equipment as safe as is
humanly possible. It is a low voltage unit, its die-cast aluminum case is
electrically grounded so that in the remote event of an electrical failure
everything is contained within the metal cese . in fact it is so safe
that all Sun-Lite equipment is insured by Lloyd's of London.
However with any household electrical appliance you naturally take
certain precautions such as turning the power off before connecting or
disconnecting, you do not put your fingers into open sockets, and you
replace frayed or worn cord connections. The same common-sense pro-
cedure should be followed in using Sun-Lite equipment, as otherwise an
unpleasantly severe but not dangerous electrical shock can result.
When putting your Sun-Lite equipment away first turn the battery
pack switch to the "off" position (on AC units pull the plug out from the
household electrical socket) before disconnecting the Flash Head. AI-
ways disconnect the Flash Head from the battery pack as a safety switch
then makes it impossible for your batteries to run down even though the
battery pack switch is accidentally pushed back to the "on" position.View original page 8Page 9 · Read text
www.butkus.us when taking pictures with battery pack units be sure to turn the battery .pack switch to the "off' position between shots if you wish to get the most from your batteries. If the battery pack switch is left in the ;on,' position for long periods of time such as during a basket ball game there is continual drain on the voltage-doubling battery. In the case of the Model 225 this is nor too important since the #726 voltage-doubling battery is built to stand heavy use of this kind and still will probably outlasi the power battery. However, this continuous drain becomes very important when using the Pocket-Pak-Model 240-since the small Pen- lite cells exhaust themselves rapidly under such circumstances, and there' fore will have to be replaced fairly often. In either case the pouer battery is not appreciably afiected by leaving the battery switch in the "on" position as there is very little drain on it. Leaving the switch on is per' fectly proper p.o""du." with the Model 225 and is also proper with the Pocket-Pak proVided you realize you rvill have to replace the small Pen- lite cells fairly often. synchroni zal ion Nfost of the modern cameras haye provision for electronic flash nhich consists of either an "Xo' setting on the shutter or in the case of focal plane shutters built-in synchronization at the slow shutter speeds when the curtain shurter is fuily open. In addition, certain other cameras will synchronize with electronic flash by using the shutter speeds recommended in the camera manufacturer's instructions. If you are going to use elec- tronic flash it is highly desirable to use a camera that has provision for synchronization with electrorric flash or else to have shutter contacts for electronic flash installed in your camera, which your dealer will be glad to arrange for You. However, if your camera is synchronized for flash bulbs the Sun'Lite Adjustable F-M Synchronizing Adapter can be used to obtain synchroniza' tion. The F-M synchronizing Adapter makes it possible to use Sun-Lite equipment with cameras having built-in synchronization for flash bulbs but no provision for synchronization with electronic flash. since flash bulbs require varying amounts of time to reach their peak intensity, con' tact in the shutter is usually made from 5 to 20 milliseconds beforeView original page 9

the shutter is fully open. Since electronic flash
is instantaneous, it is necessary to use a mech-
anism that gives a corresponding delay to
prevent the electronic flash tube from being
fired before the shutter is fully open. The Sun-
Lite Adjustable F-M Synchronizing Adapter
contains an adjustable relay which allows you
to synchronize Sun-Lite equipment with shut.
ters that have built-in synchronization requiring
5 to 20 milliseconds delay.
The Synchronizing Adapter plugs into the
shutter cord outlet of any Sun-Lite flash head
and the red dots should be matched up in
order to obtain proper polarization. Then the
cameraos shutter cord is plugged into the outlet
of the Synchronizing Adapter, again making
sure that the red dots coincide.
To obtain synchronization with cameras hav-
ing between-the-lens shutters with an F or M
setting, the small screw at the top of the
Synchronizing Adapter should be turned so
the small dot is opposite the F or M setting,
whichever is used on the camera's shutter.
where you- have both an F and an M setting on the shutter, the F setting
is pre{erable. In certain cameras the shuttei speed determines the amounf
of delay required, and the camera manufacturer's instructions should be
carefully followed. If the camera's instructions say that Class F bulbs
should be used at certain speeds, then the synchronizing ddapter shouldbe set at F. If the camera instructions state that clasi M t should
be used at certain shutter speeds or thar only Class M bulbs"tusshould be
used, the Synchronizing Adapter should be set at the M setting.
In the case of focal plane shutters which have built-in synchronization
fo-r flash bulbs, the shutter speed should be set at the fa-stest speed at
which the curtain sh-utter is fu_lly open, and the M setting on the Synchro-
nizing Adapter should be used.
- To check synchronization with between-the-lens shutters, the back of
the camera should be opened and the Flash Head should be'placed across
it so you can see the flash through the lens from the front of the camera.
If the camera is in synchronization you will see a full circle of light
when the flash is fired. If you do not see a full circle of lieht. the adirist-
ment screw on the synchronizing Adapter should he turnid slightly-and
the light. flashed again. If synch-roniiation is still not obtain"ed,' keep
turning the adjustment screw in the same direction until a full circle oflight appears. Ir is usually simpler to start at slow shutter speeds anJ
then. when- synchronization_ is obtained, increase the shutter speed as de-
sired, making any minor adjustments necessary. If the back of 'the camera
cannot be removed, bromide paper can be inserted in the place of filmto check synchronization.View original page 10Page 11 · Read text

Synchronization with focal plane shutters can be checked by observ-
ing the flash or by using bromide paper. Make sure that the shutter is
fully open by using the proper speed, as otherwise only a portion of the
filmwillbeexposedn,-...
The adjustable relay is so constructed that you can turn the adjusting
screw indefinitely in either direction. As you turn the screw through lB0
20degrees, the electrical delay varies from five milliseconds (F) to
milliseconds (M). The setting for Polaroid cameras is approximately 14
milliseconds or three fourths of the way from the F to the M setting.
In using the Sun-Lite F-M Adjustable Synchronizing Adapter, re-
member that the recycling time is increased by about double because of
the condenser in the Synchronizing Adapter. If you are unable to obtain
synchronization you should consult your dealer, as possibly the shutter
is slightly out of adjustment.
mointqining your Sun'Iite
Electrically and mechanically, you should have little difficulty in secur'
ing the type of pictures you have a right to expect from your Sun'Lite
Speed Flash. However, an understanding of how the unit operates and
its proper care, will enable you to secure greater satisfaction.
your req dy light
This light which is located on the top at the
back of the flash head is of the oscillating type
so that by watching it you can determine the
condition of the battery that powers your unit.
When it comes on, and oscillates rapidly, the
condensers in your unit are fully charged and
your flash tube will deliver its full output.
In rvarm weather with fresh batteries, this
should be between four and five seconds. In
cold weather with batteries that are nearly
ready to be replaced, it can be as long as eight to ten seconds' When the
flash oscillates rapidly when turned on, it indicates your batteries are in
good condition. When it slows down so that it flashes only once or twice
per second, and the ready light takes B to l0 seconds to come on at nor-
mal temperatures, your batteries should be replaced. The intensity of the
flash is not materially affected by the condition of the batteries since, if
the ready light comes on at all, you will receive sufficient illumination.View original page 11Page 12 · Read text
The shelf life of batteries depends principally upon temperature. rn
cold climates batteries will last from nine months to a year. Heat is the
worst enemy of dry batteries and high temperatures materially cut their
shelf life. Therefore your Sun-Lite equipment and batteries should not
be exposed to unusual heat. Storage'in an attic or keeping the equipment
in a hot auto trunk, for instance, will materially reduce both the length
of life of your batteries and the number of flashes they will produce.
The Sun-Lite Sunflector represents one of theyour sunf lecf or greatest advances in reflector and tube design
in the last twenty five years. It utilizes a rela-
tively small light source together with a reflec-
tor with an entirely new contour. As a result,
you receive much more light than has been
possible before without increasing the electrical
input. It is so designed that you receive plenty
of light down the middle for distance as well as
excellent illumination at the edges of your
picture.
The Sunfleetor is easily removable from the
Flash Head socket which enables you to pack
it easily or even put it into your pocket if you
wish. Holveyer care should be exercised to see
that the reflective surface is not marred or
scratched. since this can affect the pattern of its light.
The sun-Lite sunflector has been surface-treated by a special process
called alchemizing. This treatment protects the surface and contributes
considerably to the effectiveness of the light output. If, after long usage,
it should become dull from accumulation of dust and grime, it can be
brightened again by wiping it off carefully with a soft rag dipped in
warm' soapy water. It should be rinsed and dried with a soft cloth. Do
not use any abrasive or harsh soaps, or any chemical metal polish.
replqcing botteries
when the ready light indicates your batteries need replacing, the
battery pack should be opened as previously described, making sure the
Flash Head is first disconnected.View original page 12Page 13 · Read text

Model 225. To replaee the batteries in
the Powerhouse Power Pack, first replace the
Eveready ff492, removing the connecting cords
from the battery one at a time, pulling the
little pin straight upward. Do not remove both
connecting cords at the same time as in this
way you could secure a shock which. whilc
not dangerous, would prove uncomfortable.
Lift out the battery and set the replacement
in the same position and replace the connect-
ing cords one at a time, inserting the pins into
the holes provided in the battery. Please note
that the long, black cord is for the negative
pole of the battery which is so marked, and
the short, red cord is for the positive pole of
the battery, which is also marked. You will note that the positive cord
has a larger prong which will not fit into the negative socket of the
battery, so there is no possibility of error if reasonable care is used. you
will also note thar there is a center hole in the battery which is not used
in this unit and under no circumstances should either pin be inserted in
the center hole.
The smaller battery is a 4/2 volt Eveready Battery No. ?26, which
operates the voltage doubler. To replace it, no special care is needed.
Simfly pull out the connecting cord which has two small prongs on it
that fit the receptacle on the battery, and replace the battery. If the
vibrator does not hum, replace fr726 before deciding a new fr492 is needed.
frlodel 24O. To replace batreries in the pocket-pak, open the case
as previously described. To replace the small Pen-lite cells remove the
metal cartridge and empty out the cells. Replace them with Eveready
f9l5 Pen-lite cells which are designed for this type of application.
Ordinary photo flash Pen-lite cells will not give satisfactory service since
they are designed for a different type of use. Insert the #915 batteries
into the cartridge in accordance with the diagram on the side of the
cartridge. If the batteries are not inserted accordins to the diasram the
vibrator will not operate.
To replace the power battery, (Eveready f49l) note the position of
the contacts, the positive (*) and the negative (-) rnarkings on the
battery and on the panel in the "Pocket-Pak" case. The markings must
coincide, allowing the small pins to make contact in the battery itself. Be
sure to replace the power battery only after the Pen-lite cells are in place.View original page 13Page 14 · Read text
If this entire procedure is not followed, no electrical connection will
be made and, as a result, the unit will not operate. If there is no hum
when the switch is turned on and the plug from the Flash Head is
connected, it indicates you have not positioned the Pen'lite cells properly
and their position should be checked. If the "Pocket'Pak" hums but
does not charge the Flash Head, it means that you have inserted the
power battery upside down and the contact pins are not touching the
contacts on the battery. It is not desirable to remove batteries any oftener
than necessary, as the contact points will not make as good a connection.
reforming
condensers
The Sun-Lite II uses ,fr" f"t".t developments
in electrolytic condensers. These condensers
are highly efficient and, therefore, have a very
low leakage factor which gives you economy
in operation. However, if they are not used
with reasonable frequency, they tend to lose
their residual charge. If the unit is used every
week or two this is not of any consequence
but should the unit lie idle for some time, to
re-charge or "re.form" the condensers will
place a fairly heavy drain on the power battery,
using up from 100 to 200 flashes. In the case
of the Powerhouse Power Pack where the
batteries have great recuperative power this
is not of too mrrch conseguence. However, in
the case of the Pocket-Pak where the bat'
teries have less recuperative power this drain
can be quite serious. It is suggested that if
the Pocket-Pak has lain idle for two or three
weeks, an AC Aoapter be used to re-form the
condensi:rs before using the Flash Head on
the Pocket-Pak. This same procedure should
be followed in any event if the unit has been
idle for more than two months regardless of
the power pack used. If you do not have an
AC Adapter take your Flash Head to your
dealer who will be glad to perform this service
for you. In this connection it should be re'
membered that frequent use prolongs the life
of condensers which normally last for years.View original page 14Page 15 · Read text

Here ore some of rhe rhings you should
know obouf electronic flqsh
Electronic flash is still so new, its equipment so varied, and its ter-
minology so confused, that it is difficult to discuss it in words rvhich con-
vey the same meaning to all photographers.
One of the first problems is defining light output. Light output has
generally been based on the amount of energy released by the condensers
during each flash, which has led to the so-called "watt second" rating.
However, the efficiency of the circuit, the efficiency of the condensers,
the relative position of the various component parts in relation to the
flash tube, and the efficiency of the flash tube and reflector, all con-
tribute to vary a watt second rating. Your Sun-Lite unit is rated elec-
trically at 50 watt seconds but it actually gives you better negatives than
electronic flash units rated at 100 watt seconds and more.
Electronic flash produces a color spectrum that is close to that of day.
light with a slight inclination towards blue as compared with bright
sunlight. The temperature of your Sun-Lite is approximately 6400 degrees
Kelvin which compares with 6000 to 6500 degrees for bright sunlight.
Where haze or overcast skies are present, electronic flash is almost a
perfect color balance with daylight.
One of the effects that you will encounter when using electronic flash
results from extremely short duration of the flash rather than from any
inherent characteristic of the light. Normally, the change in film density
is proportional to the product of the intensity of the light and the duration
of the exposure. However, due to a peculiar photo-chemical sluggishness
of the emulsion, this "Reciprocity Law" does not become operative when
using ordinary flash bulbs until the exposure has been prolonged for
several hundred micro-seconds. Take a look at the characteristic
Density/Exposure curves supplied by your film manufacturer. The higher
the curve lies on the density scale, the greater is the speed of your
emulsion. The steeper the curve, the greater will be the contrast. Notice
how the curve flattens out near the lower end and becomes nearly
horizontal. This is the region where you operate when using electronic
fash or high shutter speeds, and this is the region that produces flat
negatives, lacking in contrast.. Electronic flash, because of its high
intensity, places you much higher on this curve than you might expect
from your experience with flash bulbs. Actual experierrce with electronicView original page 15Page 17 · Read text

roking block ond whire pictures
with your 5un-Lite
In taking pictures with electronic flash it is advisable to use a fairly
fast shutter speed to exclude other sources of light. When using an in-
between-the-lens shutter, a speed of l/I00th is recommended for use in-
doors and as high as l/200th outdoors. In the case of focal'plane shutters
this is of course not possible as the shutter u'ould not be fully open and
only a portion of the film would be exposed. With focal plane shutters
the camera manufacturer's instruction manual should be consulted and
vou should use the highest shutter speed ar which the shutter is fully
open.
To secure proper results on black and white film, it is necessary, of
course, to use the correct guide number. To use a guide number you
divide it by the distance in feet to obtain the f. stop on your shutter.
Thus, if your film has a guide number of 200 and your light is l0 feet
from the subject your f. setting is 20 (200 --:- l0 20). With normal -development in the more energetic developers the following guide num-
bers roughly apply. However, if certain fine grain developers are used,
the guide number will be materially reduced. If you do nor develop
your own film, we suggest you find a processer who is familiar with
electronic flash and will give your negatives proper treatment. If you
develop your own film, prolonging the development will give you much
higher guide numbers.
The following guide numbens are listed for different films, but at first
we suggest you keep a record of your exposures until you determine for
yourself what is the best guide number for the type of photography you
require.

However, with the wide latitude that exists in black and white film,
it is suggested that you take a roll of film and determine your own
guide number by using the following procedure:View original page 17Page 18 · Read text
Set your camera on a tripod at 15 feet from a fixed subject under
ordinary indoor conditions in which you would normally take pictures.
Then take a series of exposures at various f. stops. A suggested range (
would be from f..B to 1.22 at 15 feet, or the number of f. stops can be
lessened by taking two or three each side of the suggested guide number
for the film you plan to use.
When shooting into infinity (no background), such as at basketball
, and football games, or into the center of a large room, the guide number
will be reduced by roughly one third, which again can be determined bv
experimenting as above.
In the case of electronic flash, a great improvement in results may
, be obtained by using special development. If you do your own develop-
ing, or if you have a processer who is familiar with electronic flash,
we recommend the use of the new, more energetic developers such as
Eastman DK 60a, Ansco Permadol, Edwal Minicol, or Ethol 90. The
slower-acting fine grain developers cut the speed and give you poor
negatives unless development is unduly prolonged. When using the
recommended energetic developers at lr/2 times normal, unusually high
guide numbers can be obtained, and still keep excellent contrast in the
negatives and prints.
toking color pictures
In taking color pictures where many more complex factors exist and
since color emulsions do not have the latitude of black and white. much
greater care must be observed.
Since color film is much more critical than black and white. the various ' factors affecting it must be carefully taken into account. In the first
place, the color temperature of the Sun-Lite Portable Speed Flash is 6400
degrees Kelvin. This means that where exact color balance is not required
most users will be satisfied with the pictures obtained without using a
filter on all daylight types of color film. However, where perfect color
balance is required such as for Graphic Arts reproduction for color
printing, color film should be corrected with the proper filters. While the
correction is slight it cuts down the guide number, and this factor must
be taken into account. The next factor is the light absorption of the
subject and the background. For instance, in taking pictures outdoors
into infinity with a shutter speed of 1/20fth which would preclude any
daylight from acting on the film, a low guide number will be obtained
since there is no benefit of "bounce" or reflected light. On the other
hand, taking pictures indoors at the same shutter speed, if the walls are
light in color and have a smooth surface, much higher guide numbers
will be obtained. Thus in a white tile swimming pool where reflectivityView original page 18Page 19 · Read text

1^..."
would be at its peak, you would have to use mueh smaller epertures to
avoid over-exposure.
Again, in selecting guide numbers, it is almost impossible to give a
fixed rule for any type of film and, therefore, when you are taking color
pictures, it is necessary to bear in mind the varying factors which will
affect the results and to do a little experimenting under different light
conditions to know what your Sun-Lite unit will produce in connection
with the type of film you intend to use. B_*kr'gt V9
In the ease of daylight Kodachrome satisfactory pictures can be
obtained without the use of a filter, although an Bl-B Wratten-type filter
can be used for better color balance. Where absolutely perfect color
balance is required, such as in Graphic Arts reproduction, the proper
correction is the use of a CC-IOG filter in combination with a CC-10
CYAN. For Graphic Arts four-color reproduction we recommend a guide
number of 30. However for ordinary amateur use I guide number of
between 35 and 50 is practical depending on the light absorption of the
subject and the reflectivity of the background. Guide number into infinity
(no baikground) is 30. Unless there is good reflectivity in the back-
ground of the setting, guide numbers above 40 should not be used. The
guide number for Kodachrome is from 65 to 80, depending on the sub-
ject and the background.
Generally speaking, Ektachrome gives highly satisfactory results with
no color filter, but where absolute color balance is required the
proper color correction can be obtained by using a Wratten Bl-C filter.
For Graphic Arts four-color reproduction, a color guide number of 30 is
recommended, particularly where a filter correction is used. However,
for ordinary amateur use where a filter is not used, a guide number of
between 35 and 50 is obtainable, depending on the light absorption
of the subject and the reflectivity of the background. Guide numbers
above 40 should not be used unless there is good reflectivity in the
background of the setup. Guide number into infinity (no background)
is 30.View original page 19Page 20 · Read text
using.your 5un-Lite
for "till-in" light
Because its color temperature is almost that of daylight, electronic
flash is ideal for use as a "fill-in" light when taking pictures outdoors.
While some experimentation on your part may be necessary to secure
the desired results, the procedure is essentially simple. When taking
pictures under normal daylight conditions you simply forget that you
are using electronic flash at all and set your camera just as you normally
would when taking pictures without the aid of your Sun-Lite, using an
exposure guide or light meter. If you are taking pictures in deep shade
forget about daylight entirely and use the guide number procedure you
would follow if no outside light were present. As a result you will find
that you have filled irr the shadows and find that your pictures are far
superior to those taken without your Sun-Lite.
extension lighfs
One of the most important features of
Sun-Lite equipment is the Extension
Light which is similar in appearance to
a Flash Head and plugs into the Exten-
sion Light socket on the side of the Flash
Head opposite the shutter cord outlet.
Unlike other makes, Sun-Lite Extension
Lights contain their own condensers and,
therefore, multiply the light output rather
than divide it. Thus two lights would
double the light output, three lights triple
it, and so on.
Sun-Lite Extension Lights can also be
used as booster units by pulling out the
Sunflector from either the original Flash Head or Extension Light
thereby doubling the light output of the remaining Sunflector.
Each Sun-Lite Extension Light contains a triggering outlet so that
multiple set-ups can be triggered from any light. An additional Ex-
tension Light outlet is also provided so that additional Extension Lights
can be hooked up in parallel for back or side lighting.
As many as five lights can be operated from one power source which
is usually an A.C. Adapter for economy's sake, as the battery drain is
multiplied by the number of lights, and even the "Powerhouse" Power
Pack can be exhausted under such use.View original page 20Page 21 · Read text

-F"good luck wirh
your piclures
By following a systematic approach, noting
the cameras you use, the distances and differ-
ent apertures, and identifying your early
negatives, you will have a record that will
stand you in good stead. The same procedure
should be followed if you do your own develop-
ment and then after a brief period you will
be able to make a set of simple and accurate
procedures that will give you the photographic
results you have a right to expect each and
every time you take a picture.
If you follow the procedures outlined in
this manual you should be able to get the
most from your film and cameras. However,
the information we give you here and the in-
formation supplied by the manufacturers of
cameras and films can only serve as a guide.
Through your own experimentation and by be-
coming thoroughly familiar with your unit,
you will soon develop your oryn technique for
securing the best results from your Sun-Lite.
