The Impact VC-500WL 2-500Ws Monolight with Transmitter Kit (220V) is built around 2 enhanced, redesigned VC-500WL flash heads. Each head comes with a reflector, flashtube, 250W modeling lamp, power cable, sync cord and a 9.4' air-cushioned light stand. The included 16-channel, 4-group radio transmitter triggers the head's built-in receivers from up to 328' away. Two white umbrellas with black backing, a 24 x 36" softbox with silver interior and speedring, and a wheeled case are also included.
The VC-500WL 500Ws monolights have full to 1/32 power range adjustable over 6 stops in 1/10 stop increments, very fast recycling time (1.5 seconds @ full power) and Proportional, Independent and Off settings for the 250W modeling light. Flash durations as short as 1/1200 sec. freeze action with moving subjects while the VC-500WL's 5,600K color temperature remains constant within +/- 100K regardless of power setting.
You can freely mix and match your remote flash units with the VC-500WL. The flash's 7 optical slave modes allow it to interface with an on-camera TTL flashes, triggering with up to 5 pre-flashes when needed. The VC-500WL's Time Frame and Block Time functions enlarge the unit's circle of compatibility with the many brands available by effectively adapting for the differences in their pre-flash durations.
A number of systems are employed to increase the VC-500WL's longevity and ensure safety. The fan-cooled housing with adaptive thermal control protects the flash heads CMOS circuitry and the user-replaceable modeling lamp and flash tube.
