Ranger Quadra RX the ultimate mobile battery pack Light.
Photoquip (Elinchrom India) asked me to do a video on the 'Quadra Ranger RX' last year. Before making the video, I used it extensively, and I loved this product. It is a fast, robust, reliable, and compact flash system, and I use it whenever I shoot outdoor. I recently upgraded this pack with ELB 400, but it's still a powerful strobe light.
Check out this video and let me know if you have any queries. Happy Clicking!
