The ARRI ST1 Studio 1000W Fresnel with Stand Mount represents a major update of this well-known industry standard. Features include reduced weight, a compact size, a maximum light output, and 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. It has reduced the lamp housing temperature of this black 1000W Fresnel 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.
