THE EVOLUTION
Of Authentic ARRI TRUE BLUE Lighting
ARR 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, ARR 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.
ARR ’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. t’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. mproved 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.
ARR 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.

True Blue offers two new designs of top latch to suit the application. The
Studio Top Latch is simple and easy to use and can be turned completely out
of the way to load and unload accessories. The Location Top Latch is
specially coated for improved corrosion resistance and is sprung loaded for
fast operation even when hot.
Top Latch
Finally an easy solution to an old problem. Location crews need space in the
accessory bracket for up to four scrims; studio crews suffer from the light
leak this creates. Now two-position TRUE BLUE accessory brackets quickly
adjust in or out for two or four scrims. By reducing the space between the
scrims and the lens, unwanted reflected and spill light is minimised.
Adjustable Accessory Brackets
TRUE BLUE fixtures have been designed for serviceability with more common
parts across the line. Removing a maximum of six universal Torx screws
provides easy access to all interior parts. TRUE BLUES require only three Torx
drivers to disassemble the complete fixture.
ARR ’s new aluminium extrusion makes cleaning fixtures easy and our new
paint process ensures that TRUE BLUES will look as great as they perform.
Maintenance
We’ve named this component after its inventor and the principal designer of
ARR TRUE BLUES. With this combination connector and strain relief, the
power cable can be quickly reoriented for stand mount or hanging fixtures.
n addition, the connector, along with ARR ’s new lampholder, allows us
to eliminate the interior terminal block.
* Patent pending
Ste maier Connector*
ARR ’s cross cooling* system moves a stream of air around the Fresnel lens
and through the lamphead. n addition, air is channeled through the
aluminium extrusion housing, reducing lens temperature by 17% and
housing temperatures by 25%. Cross cooling* allows ARR TRUE BLUES to
safely operate at almost any tilt angle.
*Patent pending
Cross Coolin *
Modern fixtures use a wide variety of Chimeras, scrollers and other front
mounted accessories. Simply slide ARR ’s innovative stirrup bracket to quickly
and easily adjust the fixture’s centre of gravity.
* Due to the smaller size of the fixture, the sliding stirrup is not used on the T1.
Slidin Stirrup
ARR ’s new design creates a positive lock so there’s no slippage when using
heavy accessories. A stainless steel friction disc functions like a disc brake
allowing the lamphead to be completely locked off with a minimum of force.
* Due to the smaller size of the fixture, the friction disc tilt lock is not used
on the T1.
Tilt Lock
TRUE BLUE fixtures are
manufactured to the P23 standard
and are suitable for indoor use or
outdoor use providing a degree of
protection against falling rain (up to
a 60˚ angle from vertical).
Improved Weather Protection/IP23
All True Blue fixtures carry not only CE declaration but also an independently
assessed TUV certification.
Safety Certification
New ARR barndoors use a special alloy with a high strength-to-weight ratio.
The leaves in our new design withstand bending and deforming far better than
traditional barndoors. n addition, leaves are now easily tightened to avoid
slipping and the larger leaf design provides better control and sharper cutoff.
The same features are incorporated in a new optional eight leaf barndoor.
Barndoors
Although the top latch holds
accessories securely at any tilt
angle, both Studio and Location
lampheads feature a second safety
catch mounted on the bottom
accessory bracket. This eliminates
the need for a barndoor safety bond
without restricting the rotation.
Barndoor Safety Catch
The laser cut hexagonal
safety mesh maximizes
light transmission and
is tough enough to
withstand location abuse.
Stainless Steel Lens Protection
Easy to carry, ARR ’s new aluminium extrusion stirrup is smooth, incredibly
strong and extremely lightweight.
