Arri ST1 True Blue 1K Fresnel Spot Light with 7" Lens. CAT# 552100. True Blue by ARRI is the newest generation of ARRI's lighting product range, representing an unprecedented evolution of studio and Tungsten fixtures that have been popular workhorses for over two decades. Following extensive research and feedback from respected lighting professionals, combined with great advances in technology, ARRI introduces a selection of highly innovative lampheads with over 30 new improvements for studio and location lighting. Reduced weight, compact size and maximum light output are just a few of the benefits. While the overall weight of the TRUE BLUE fixtures has been reduced, there have been no sacrifices to quality; in fact many components now offer greater strength and resistance to corrosion. Maintenance and repair are facilitated by simplified access to internal components, and the smooth lamp housing surfaces are now easier to clean. One particular focus of enhancements to the lampheads has been their adaptability to accessories. The tilt lock has been dramatically improved by a stainless steel friction disc that locks tight to eliminate the danger of forward tilting when heavy, front-mounted accessories are in use. In addition, a new stirrup centre adjustment allows the lamphead to slide until its centre of gravity is either at or near the tilt lock, depending on the accessories attached. The new Stegmaier connector, a rotatable cable outlet, permits swift adjustment between ideal cable orientations for both ceiling-grid and floor-stand mounting. Improved barndoors are stronger, less susceptible to bending, and can be inserted vertically without being damaged when the lamphead is placed on a flat surface. ARRI's new 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%.

General 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: maximised 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
  • Safety Certification: CE, TV-GS, NRTL-US-C
