This is an Impact Cool Light Kit.
The Impact Five Lamp Fluorescent Cool Light accepts screw-in fluorescent lamps.
Independent switches on the rear of the unit vary light output across a three f-stop range, by selecting between one, two, three, four, or all five lamps.
This 150 Watt fluorescent head provides 7,500 lumens, and is 5500°K daylight balanced without the need for conversion filters.
The angle of the head is easily adjusted with its tilting 5/8" light stand mount and convenient positioning handle. An Impact air-cushioned light stand is included, as well as the fluorescent bulbs.
