This is an Elinchrom Ranger RX Speed 1100W/s strobe lighting kit. The "RX" signifies the ability to be fired by a remote control handset, or computer. The "AS" indicates the power pack's ability to divide the power asymmetrically between two attached Freelite flash heads. The power selection range is 7.5 f-stops. Lower the power to 7.5W/s, switch to slow recycle, and up to 5,100 exposures can be made.
Elinchrom Ranger Speed has flash durations as short as 1/2,310 second (with two "S" heads attached), ideal for sports, fashion, and theatre photography. Controls on the pack permit changing the output in 0.1 stop increments in an easy-to-read digital display.
This is a one head kit, which includes a Freelite "A" flash head, which provides an ultra-short flash duration. Also included is a 33" Varistar Umbrella/Softbox. The kit also includes a 7" grid reflector, an extra battery, multi-voltage battery charger, 16' special Elinchrom connector to PC sync cord, shoulder strap and a hard Ranger case.
