The ARRI 150W Three-Light Kit holds three ARRI 150Ws -- a small Fresnel with great performance and rugged construction. It has a 2" (50 mm) low expansion, borosilicate Fresnel lens producing a soft, even field of light. Superior optical performance and ARRI's cast and extruded aluminum housing make this an ideal small Fresnel. This is a complete lighting kit, including barndoors, scrims, light stands, spare lamps, and a hard carrying case for storage and transport.
