The Arri ST5 True Blue Series of tungsten lighting fixtures 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 easier adjustments.
When fitted with a 5000 watt bulb (available separately) this fixture will provide a 5.6' (1.7 m) diameter beam of 707 fc from a distance of 29.7' (9 m) at full spot. At full flood (same distance) it will provide a 92 fc beam 36.3' (11 m) in diameter. Control of tilt, pan and focus is possible (with an optional control pole) from the safety of the studio floor.
