Arri 1000W Fresnel
Arri's cross cooling system reduces lamp housing temperature by 25% and lens temperature by 17%. With special air channels built into the aluminum extrusion, a constant stream of air passes around the Fresnel lens and into the lamphead regardless of the tilt angle. When fitted with a 1000 watt bulb (available separately) this fixture will provide a 2.8' (0.9 m) diameter beam of 409 fc from a distance of 20' (6.1 m) at full spot. At full flood (same distance) it will provide a 48 fc, 20.4' (6.2 m) diameter beam.
