The ARRI T1 1000 Watt Fresnel Light is a large, traditional fresnel light for indoor and outdoor use (meets IP23 standard for light rain). It will provide a 2.8' diameter beam from 20' away at full spotlight mode. In flood mode it provides a 20.4' beam. It is made of pressure die cast and extruded aluminum to withstand a rugged filmmaking environment. A stainless steel friction disc locks down any large front-mounted accessories and it has a 5.91" fresnel lens inside a ribbed housing which allows this light to run a little cooler than older models of fresnel lights. The ARRI T1 features special air channels built into the aluminum for a constant stream of air passing through the lens and into the lamp regardless of angle. This light is ideal for large video and photo sets.
