The RX-11SB+HC is designed for the flexible RX-11TD LED panel. It is supplied with a detachable honeycomb grid, which can be used to direct the light. The softbox is lined with a silver reflective material, which ensures a high return of light and sufficient reflection.
The Linkstar softbox can easily be mounted on the RX-11TD LED panel using the simple Velcro system. Then you can mount the honeycomb with a velcro strap on the inside of the softbox.
