ARRI Lamphead ARRI TRUE BLUE - Manual (Page 4)

We’ve named this component for its inventor and the principal designer of
ARRI TRUE BLUES. With this combination connector and strain relief, the
power cable can be quickly reoriented for stand mount or hanging fixtures.
In addition, the connector, along with ARRI’s new lampholder, allows us
to eliminate the interior terminal block.

ARRI’s cross cooling system moves a stream of air around the Fresnel lens
and through the lamphead. In addition, air is channeled through the
aluminum extrusion housing reducing lens temperature by 17% and housing
temperatures by 25%. Cross cooling allows ARRI TRUE BLUES to safely
operate at almost any tilt angle.

Modern fixtures use a wide variety of Chimeras, scrollers and other front
mounted accessories. Simply slide ARRI’s unique stirrup bracket to quickly
and easily adjust the fixture’s center of gravity.
* Due to the smaller size of the fixture, the sliding stirrup is not used on the T1.

ARRI’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.
