^^iEC^ON ARC
Commemorating the Third of a Century of Progress in arc lamp development started by
HARRY H. STRONG (1887-1956)
* Dean of projection lighting engineers.
^ Founder of The Strong Electric Corporation, America's largest
and oldest manufacturer of projection lamps.
* Inventor of the automatic arc control system which freed projectionists
from one of their most demanding tasks.
Coiiiiiieinornthe plates iitll be tiffixetl lo all lite new V'lt'l lamps
produced in I960, honoring one oj the best friends of projectionists,
exhibitors and equipment dealers.
NEW AIRSCOPE
VENTILATING SYSTEM
25% LOWER SILHOUETTE
Uses 70% more air. More efficient than
that of any previous projection lamp.
A complete change of air every five
seconds. Although having a capacity
of 165 amperes, the lamphouse, back
door assembly and operator side door
maintains a 30° lower operating temperature.
One hundred percent more air is swept
over both faces of the cold type reflector
in the 1960 U*H*I than in other lamps.
Permits easy installation even in projection
rooms v^ith low ceilings. There is no
need to revamp the prevailing booth exhaust
system if it has been adequate for
use with lamps operating at 90 amperes
or higher.
NEW HYDRO-TITE WATER
COOLED CARBON CONTACT
Write for free literattire.
BOXOFFICE :: May 9, 1960
Simple clean design. Employs a one-piece
water conducting tube for each contact
that is fully enclosed to forego any possibility
of breakage. No water connections
at the carbon contact, no flexible tubing,
or clamped or welded connections to the
contact, any of which might be subject
to leakage.
Heavy duty, long life, pure silver
water cooled positive carbon contacts
are standard.
PERMITS GREAT
CARBON SAVING
With the economical full 20-inch 1 3.6 mm
positive carbon, the 1960 U>H*I projects
an extra double reel of 35 or 70 mm
film more than projection lamps which
cannot accommodate this carbon length.
INTEGRATED EXCLUSIVE
STRONG LIGHTRONIC
CONTROL AT NO EXTRA COST
—advances the carbons as they are consumed
by means of separate famous
Bodine geared head feed motors, to
maintain a uniform arc gap length and
to accurately position the positive arc
crater at the exact focal point of the
reflector. A screen light of constant
intensity and color is automatically maintained
without constant attention from
the projectionist. The position control
system operates over the complete
current range of the lamp and does
not require the projectionist to reset
it
when changing the range of operation
or when changing from 35 mm to 70 mm
format.
