The Arri T24 Fresnel Stand Mount version is a very large tungsten Fresnel unit that accepts 24,000W or 20,000W lamps and is designed to illuminate large scenes with maximum coverage. The all-aluminum, corrosion resistant construction of the T24 was designed to withstand the rigors of location shooting. Power is pointless without control, so the T24 was designed with a variable beam angle of 14-55° and a precision 24.6" Fresnel lens to ensure even coverage of the scene, free of hotspots.
To avoid high starting currents, the Arri T24 is powered by an external dimmer providing a built-in, slow start up - in effect pre-heating the filament and facilitating a longer lamp life. The T24 is fully dimmable between 0-100% and is designed to be serviced in the field. A wide array of accessories, including barndoors and scrims, are available separately to further tailor the light's output.
