The Arri 150 Watt Tungsten Fresnel Light is a compact light source with location-tough construction and a 2" (50 mm) Fresnel lens. Superior optical performance and Arri's cast and extruded aluminum housing make this the perfect small Fresnel. All lamps must be purchased separately. This fixture is equipped for 120VAC operation. It will also function with 230VAC provided that the 120V lamp carriage is replaced by a 230V carriage and the plug is adapted to your socket configuration.
