The RQ Hybrid S Flash Head by Elinchrom is a powerful, full-functioning miniaturized flash head which is perfectly mated to the 400W/s Ranger Quadra Hybrid battery-powered pack. At only 0.55 lb and measuring a mere 5.9 x 3.3 x 3.1", the head not only packs well and is eminently portable, but is mountable in situations that would be impossible for a full-sized flash head.
The "S" designation for Standard, might look like the head is an under-performer as compared to its "A" counterpart, but on the contrary, the Standard is capable of very fast flash durations as short as 1/3,000 sec. - perfectly adequate for most applications. The Hybrid S Head does away with conventional halogen modeling lamps in favor of a low-draw LED Pilotlight that produces the tungsten equivalent of 50-60W, depending on your choice of the standard, included 70 degree or optional 55 degree reflector. Elinchrom also offers the EL-RQ adapter for those who want to use standard full-sized accessories and reflectors. The head comes with a removable 8.2' head cable, while optional 5.0' and 11.5' cables are available.
