The Impact LiteTrek 4.0 DC Flash Head offers a wide array of advanced studio and DSLR-friendly features in a lightweight (2.6 lb) head intended for use in the field where AC power is unavailable.
Starting with strong core specs like 400W/s of power delivered promptly in 2 seconds at full power, the head offers 5 stops of output variability with action-stopping flash durations as low as 1/14000 sec.
Consistency is stressed at every stage of production, evident in the tight +/-100K tolerance in its 5500K flash tube. The Autodump feature automatically "bleeds" extra power from the capacitors when powered down.
Advanced features include Multi Mode which allows you to utilize stroboscopic technology for motion studies or sports, as well as Quick Mode which automatically powers down the flash to permit focal plane shooting at shutter speeds as short as 1/13,000 sec.
Convenience features include a removable power cord and stand mount for easy packing. The LiteTrek 4.0 requires a power source and is ideally mated with the optional Impact LiteTrek (LT) Battery Pack system which offers 650 maximum power flashes or 3500 minimum power flashes on a single charge.
