One of the problems generated by a light source such as a 12K or larger is the tremendous heat transmitted from the front of the light. When trying to diffuse the source with silk or lighting control filters, extreme temperatures will destroy these materials.
The Extension Ear will allow the diffusion frame to be positioned at a variable distance away from the light source, thereby avoiding the intense heat, and creating an even spread of the light.
This is a set of 3 ears, which provide the best support for the frames you use.
