The Diva Ring Light Tripod Neck Adapter is an upgradable mounting accessory for your Diva Ring Light. Unlike the Z bracket which mounts the DRL and your camera onto the head of your tripod, the Tripod Neck Attachment allows you to mount your DRL onto the center column of your tripod. This makes it so you can mount your camera to the head of the tripod directly, adding extra stabilization.
This is helpful in situations where you want to move your camera independently from a Diva Ring Light, or if your camera is too heavy to be supported by the Z bracket.
