The Elinchrom D-Lite 400W/s RX 4 Flash Head raises the bar on the capabilities of a lightweight, portable strobe. The auto-sensing, multi-voltage flash D-Lite RX 4 recognizes any AC power source from 90-260VAC, allowing power variability over 5.0 stops in 1/10 stop increments. Recycling is a lightning-fast 0.35-1.6 sec. (115V) with flash durations as short as an action-stopping 1/800 sec at full power. But that’s just the beginning.
