The Arri ST-2 2000 Watts Studio Fresnel Light, Stand Mount (Black) updates a well-known industry standard. Feedback from respected lighting professionals combined with great advances in technology enable Arri to present a selection of Fresnels with over 30 new improvements for studio lighting. The tilt lock has been improved by using a stainless steel friction disc that locks tight. This eliminates the danger of the fixture suddenly tilting downward when heavy, front-mounted barndoors or softboxes are in use. In addition, a stirrup center adjustment allows the head to slide until its center of gravity is either at or near the tilt lock. This assures a better balance and less chance of the fixture toppling over.
When fitted with a 2000 watt bulb (available separately) this fixture will provide a 982 fc beam 3' (0.9 m) in diameter from 19.8' (6 m) at full spot. From the same distance it will throw a 106 fc beam 21.1' (6.4 m) in diameter at full flood.
