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.
