Overview
The Nanlite Diffusion Dome for FM-Mount Reflector is a compact light-modifying accessory designed to work with the RF-FMM-45 reflector system used on Nanlite FM-mount fixtures such as the Forza 60, 60B, 60C, and 150 series.
This hemispherical diffusion attachment snaps directly onto the front of the reflector and transforms the output from a controlled hard beam into a soft, evenly diffused light source while maintaining directional control.
By spreading and softening the reflected beam, the diffusion dome produces smoother shadows, reduced contrast, and more flattering light quality, making it ideal for portrait photography, interviews, product work, and cinematic lighting setups where natural-looking highlights are required.
The dome is made from a flexible translucent silicone material that helps scatter light evenly while maintaining shape stability during repeated use. Its snap-fit design allows for quick installation and removal on set without tools, making it highly practical for fast-paced production environments.
When used with FM-mount reflectors, the diffusion dome expands the beam spread significantly while maintaining the efficiency and directionality of the reflector system, giving users a balance between softness and control that is difficult to achieve with traditional softboxes alone.
This accessory is part of Nanlite’s FM-mount ecosystem, designed to enhance creative lighting control in compact COB LED setups used in film, photography, and broadcast production.
