These views 0/ production processes in the Strong Electric Corp. factory are<br />
indicative of the precision engineering that is stressed At left, the workman<br />
is forming gloss reflectors. In the center is a scene in the engineering department<br />
where problems are worked out before production is begun. At<br />
right, an inspection is being made of a projection arc lamp reflector.<br />
The Strong Corp. is the largest producer of projection arc lamps.<br />

which employed a reflector would result<br />
in the required high efficiency. Such a<br />
lamp furthermore would have to be built<br />
to Underwriters special requirements, as this<br />
lamp would usually be in the hands of a<br />
layman. If the lamp was to be small, the<br />
carbons would have to be short, which<br />
meant they would have to burn very slowly,<br />
for a trim would have to last almost an<br />
hour.<br />
FINALLY LICKED THE PROBLEM<br />
To get these short carbons to burn an<br />
hour, we tried burning them at less than<br />
their rated current capacity, but this only<br />
led to unstable burning of the arc and a<br />
continuous changing in color. It was only<br />
by a most intensive effort, with much<br />
sweat, tears, profanity and almost blood,<br />
that we licked the various problems of<br />
building such a lamp. However, by 1936<br />
Strong Electric had finally developed the<br />
16mm Junior High, a reflector-type high<br />
intensity lamp, which delivered about four<br />
to five times as much light as was possible<br />
to get from an incandescent light source<br />
and the light was snow-white in color, a<br />
particular advantage when color films<br />
were shown.<br />
AN INEXPENSIVE LAMP NEEDED<br />
In 1938 there were only about 4,000<br />
theatres<br />
equipped with the various types of<br />
high intensity lamps. The other theatres<br />
needed high intensity lamps very badly but<br />
couldn't afford even the "Suprex" lamps.<br />
The AC lamp had proved to be a flop and<br />
low intensity lamps were no longer adequate<br />
for even the smaller theatres, because<br />
of the trend to larger screens of porous<br />
structure. The more dense films which<br />
were being released as a means of improving<br />
picture quality, and the color films<br />
which could be pleasingly projected only<br />
by the white light of the high intensity.<br />
All the lamp manufacturers directed<br />
every effort to design and build a low cost,<br />
economical lamp that would capture this<br />
potential market.<br />
Our experiments on the 16mm projection<br />
lamp stood us in good stead but only by<br />
concentrated effort, working around the<br />
clock, subsisting on hot coffee and cold<br />
sandwiches, harrassing everyone in the engineering<br />
department, and driving all other<br />
members of the organization to a point<br />
where tempers let go and nervous indigestion<br />
set in, were we able to finally get the<br />
answer. By burning "Suprex" high intensity<br />
carbons at the relatively low current<br />
of 40 amperes, we attained a low power and<br />
carbon cost. This lamp, known as the<br />
Strong One Kilowatt, projects twice as<br />
much light as the low intensity lamp, a<br />
light very white in color, and gives the<br />
moderate size theatre, with a screen up<br />
to 18 feet in width, a type of projection<br />
comparable to that of the large theatres,<br />
but at an original and operating cost within<br />
their means. Since the day it was first<br />
introduced, it has continued to be sold in<br />
large numbers.<br />
THE VICTORY LAMP WAS BORN<br />
World War IX brought a demand from<br />
the armed forces for projection equipment<br />
which could be built almost entirely without<br />
the use of strategic materials such as<br />
aluminum and copper. In answer. Strong<br />
Electric developed the Victory lamp, a high<br />
