ARRI A4 Work Light User Manual


 
Wherever the highest standards of theatre
lighting are required, ARRI Daylight and
Tungsten lampheads are used world-wide.
For the highest quality Daylight Fresnels
the Compact Theatre range offers sizes
from 2.5 to 6kW. These are supplemented
by the Tungsten Fresnels of the Studio
Theatre range from 1 to 5kW.
More specialised requirements can
generally be met by lampheads from
other ARRI Lighting ranges such as the
discharge ARRISUN PARs and the
ARRI X flat-field floodlights.
ARRI technology can also be combined
with theatre technology from other
manufacturers. Electronic ballasts can
be adapted for use with discharge follow
spots and we also offer a modification
kit for fitting a discharge lamp to the
ETC Source Four.
ARRI Theatre lampheads have been
developed for the special requirements
of Theatre, Opera, Musical and Festivals.
Intelligent design features guarantee
simple and effective operation even in
difficult conditions. The wide range of
lampheads and accessories even including
the option of full motorization of all
functions gives the designer the power
to achieve his creative ideal.
SPECIAL FEATURES
Spherical dichroic glass (cool light)
reflector increases optical efficiency,
optimises heat dissipation inside the
head and ensures longer life for gels.
Internal baffles eliminate spill light.
Specially designed front cassette
blocks light reflected off the back
of accessories.
Adjustable balance point and reinforced
friction clamp guarantees safe operation
even with heavy accessories.
Optional ‘rear-loader’ rear lamp change
available on some lampheads is safer
with heavy accessories or where
lampheads are mounted on catwalks.
Tungsten heads supplied in black and
discharge heads in graphite grey to
harmonise with the theatre environment.
Accessories are interchangeable
with those of equivalent ARRI
standard lampheads.
DMX controlled accessories available
including magnetic and electronic
ballasts, dimmer shutters, scrollers,
even up to complete motorization
of all functions.
MB Ready Lamphead option for
compatibility with motorized stirrups.
