The Profoto D1 Air 500Ws 2-Monolight Studio Kit w/o Remote (90-120V & 200-240V) gives you a total of 1000Ws of Profoto digital lighting power, with color temperature and exposure consistency across the entire 7 f-stop power range (thanks to the dual mode SMPS capacitor charging technology). This kit also includes 2 light stands, 2 umbrellas, a sync cord and a studio kit case for storage and transport.
A built-in reflector controls stray light from the flash head, and it's designed for use with other reflectors, softboxes and umbrellas. Easy-to-use controls help you take advantage of the D1's fast recycling time (0.95 seconds @ full power), short flash duration (1/1000 to 1/2600 sec. @ t0.5) and 1/10 f-stop precision exposure control. Air Remote Control not included.
