The Arri True Blue ST1 L1.40505.H is a 1000W hanging studio fresnel lamphead in black. ARRI True Blue represents an unprecedented evolution of the 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. ARRI True Blue T1 is available in both manual and pole-operated versions.
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 lamp head 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 accessories. To make balancing the lamphead even easier, the sliding stirrup mounting can be adjusted to counterbalance all accessories. The new extruded aluminium stirrup is stronger, lighter and less bulky, but still permits full fixture rotation; its soft contour also makes the lamphead more comfortable to carry. Improved barndoors are stronger and less susceptible to bending, with a new hinge design that maintains constant, easily adjusted tension.
