The ARRI ST2 is a highly regarded workhorse in motion picture, television, and still photography lighting. It is a 2000-watt tungsten Fresnel fixture that uses ARRI's specifically developed reflector and high-quality lens to provide a smooth, even field of light. The Fresnel design allows the light beam to be easily focused (spotted) or spread (flooded) via a robust mechanism. It is constructed from durable, corrosion-resistant extruded and die-cast aluminum, making it capable of withstanding the rigors of professional use both in the studio and on location. The included four-leaf barn doors attach to the front of the fixture and are essential tools for shaping the light output and controlling spill.
