The ARRI ST1 1000W Studio Fresnel with Stand Mount is part of the ST True Blue Series of tungsten Fresnel lighting fixtures and represents a major update of this well-known industry standard. Feedback from respected lighting professionals, combined with advances in technology, enables 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 1000W bulb (available separately), this fixture will provide a 13°, 3' wide beam of 532 fc from a distance of 13.2' at full spot. At full flood, it will throw a 94.5 fc beam 57°, 14' wide from the same distance.
