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.
