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 aluminium 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 aluminium 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 balancing the lamphead even
easier, the stirrup mounting slides and can be adjusted to
counterbalance all accessories. The new extruded aluminium
stirrup is stronger, lighter and less bulky but still permits full
fixture rotation. It’s 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.
