Famous for their high-quality, even light distribution, Arri Fresnel systems are highly respected among still photographers and cinematographers alike for their accuracy, design and durability. Each Arri Fresnel has up to a 60 degree beam angle ? with a spherical, specular, high-purity aluminum reflector ? featuring ribbed aluminum housing and a 25' (7.6m) cable with a rugged in-line switch. 2000w and 5000w models include grounded three-prong plugs.
