This Dynalite SP1600 1600W/s Studio Power Pack is powerful and versatile enough to handle a wide variety of on-the-run assignments like fashion, corporate work, portraiture, weddings and interiors, but the rigors of the studio is where it really shines. If you need the speed and consistency necessary to shoot at full power all day long then this pack is for you.
The SP1600 has 4 head outlets and breaks down its output symmetrically or asymmetrically over a 6 stop range with short flash durations. Dynalite has beefed up the SP1600's capacitors and profile and added a bit of weight to give you a super-fast recycle time of 1.2 seconds at full power. A variator knob allows fine tuned exposure adjustments over 2 stops in 2/10 stop increments. Triggering options include sync cord (provided), IR or optical slave as well as a built in PocketWizard radio receiver.
Although you may be tired at the end of a long shooting day, it won't be because of your equipment. Even with all of that power the SP1600 pack weighs in at 12.1 lb (5.5 kg) and measures 7.12 x 9.25 x 7.8" (18 x 23.5 x 19.8 cm).
