The Ranger RX Speed AS is a 1100W portable battery pack unit. Recycling at full power in 3 seconds and delivering up to 250 flashes at full power makes this battery unit very powerful. Its 2:1 asymmetrical output allows fast flash durations while the 7 f-stops power range allows for precise control of light. Incorporating the most advanced miniaturized components weighing in at 8kg and controllable by EL-Skyport remote control, by iDevices, computer or by handset, the Ranger RX increases enormously the ease of using light on location. Its weather resistant design is also extremely useful. The heads are made out of lightweight aluminum to withstand heavy use. They are very portable solutions to anyone looking for high power on location. Remote control your ranger RX units with the EL-Skyport software, control up to 4 studios of 16 units and access extra features like flash counter or flash delay for second curtain sync and other effects.
