This is an Arri Arrilite 600W Three-Light Compact Kit including barndoors, scrims, bulbs, light stands, and a hard case.
The "baby" of the Arrilites, the 600 has a 5" open face and an anodized aluminum reflector for maximum light efficiency. Beam angles are 90° in the flood position and 34° in the spot position.
When fitted with its included DYS 600 watt bulb, each focusing flood will provide a beam of 240 footcandles, 6.1 ft (1.9 m) in diameter @ full spot, from a distance of 10 ft (3 m). It will throw a beam of 63 footcandles 20 ft (6.1 m) in diameter @ full flood, from the same distance.
Although this kit is supplied for use with 120 AC voltage, it can function with 220-240 voltage, with the appropriate optional bulbs, adapter plugs or cables.
