The Elinchrom RQ Ringflash is a dedicated ringlight for Ranger Quadra battery power packs, so you can bring the distinctive "shadowless" ringlight look out of the studio and on location with you. This lightweight (4.1 lbs/1.9 kg) light has a 4-pole flash tube that delivers a movement-freezing 1/2600 sec. flash duration at full power. The 6.5' (2 m) cable, ergonomic handgrip and 3.9" (100mm) internal diameter make it a natural for location work with medium format or SLR cameras. The RQ Ringflash can be used only with Ranger Quadra Battery power packs.
