About Arri ST1

The Arri True Blue ST1 Studio 1 kW Fresnel, Stand Mount (120-230 V AC) represents a major update of this well-known industry standard. Feedback from respected lighting professionals combined with advances in technology enable Arri to present a selection of Fresnels with over 30 new improvements for studio and location lighting.

Reduced weight, compact size and maximum light output are the most obvious improvements. Arri's patented cross-cooling system, which encourages a stream of air to pass around the Fresnel lens and into the lamphead from the front, has reduced the lamp housing temperature of True Blue units by 25% and the lens temperature by 17%.

When fitted with a 1000 watt bulb (available separately), this fixture will provide a 13-degree 3' (0.9 m) wide beam of 532 fc from a distance of 13.2' (4 m) at full spot. At full flood, it will throw a 94.5 fc beam 57 degrees (4.3 m) wide from the same distance.

Arri ST1 Features

  • Cross Cooling System: new, highly effective cooling streams in addition to conventional cooling
  • Sliding Stirrup: centre of gravity adjustment
  • Tilt Lock: stainless steel friction disc for rigid lock-off
  • Top Latches: application-oriented Top Latches for location or studio use
  • Adjustable Accessory Brackets: adjustable 2-scrim and 4-scrim position
  • Stainless Steel Lens Protection: maximized light transmission and high temperature stability
  • Extremely Robust Barndoors: made of special alloy with high strength-to-weight ratio and effective tightening function
  • Maintenance: more shared parts, very fast access to all interior workings with three torx drivers only
  • Improved Weather Protection / IP23: safe indoor and outdoor use
