THE EVOLUTION
Of Authentic ARRI TRUE BLUE Lighting
ARRI TRUE BLUES represent an unprecedented evolution
of the Studio and Location fixtures that have been popular
workhorses for over two decades. Following extensive
research and feedback from lighting professionals around
the world, combined with advances in technology, ARRI
has designed a series of six highly innovative lampheads
with over 30 new improvements for studio and location
lighting. With reduced weight, compact size and maximum
light output TRUE BLUES set a new standard for
professional lighting equipment.
New pressure die cast and extruded aluminum components
have reduced the overall weight of the TRUE BLUE fixtures
without any sacrifice in quality or durability. Many
components now offer greater strength and resistance to
corrosion.
ARRI’s cross cooling system* reduces lamp housing
temperature by 25% and lens temperature by 17%. With
special air channels built into the aluminum extrusion, a
constant stream of air passes around the Fresnel lens and
into the lamphead regardless of the tilt angle.
At the heart of the TRUE BLUE concept is a redesigned
stirrup and improved tilt lock. The stainless steel friction
disc locks the lamphead securely even with the largest
Chimera or other accessories. To make lamphead balance
even easier, the stirrup mounting slides and can be
adjusted to counterbalance all accessories. The new
extruded aluminum stirrup is stronger, lighter and less
bulky but still permits full fixture rotation. Its soft contour
makes it comfortable to carry.
The new Stegmaier connector* and strain relief rotate to
allow the cable orientation to be quickly adjusted for
hanging or stand mounting. Improved barndoors are
stronger, less susceptible to bending and a new hinge
design maintains constant tension that can be easily
adjusted.
Routine maintenance and repair are easier with fast, simple
access to all internal components. Cleaning is made
effortless with smooth lamp housing surfaces.
ARRI has redesigned these new lights down to the smallest
detail, offering lighting professionals better choices for
location and studio work. TRUE BLUE Fresnels from 1000
to 5000W include the T1, T2, T5, ST1, ST2 and ST5.
