I personally use a pistol grip, uk has as an option, as well as a retractor, this allows you the freedom of moving the light as needed and in case you have to let go, the retractor will assist , so it won`t drop....uk also makes a mini Q40 ,which attaches to the strap on your mask, good for photography, as it allows the light to go in the direction you are looking , hands free,.....also a back up light try Underwater Kenetics SL4 Sunlight, as it is small and can attach to several locations on you BCD, using either retractors or simple coil ring clips, small enought to fit in most pockets...have fun ,be safe.....
