The GEEK MOD SpeedRing-PRO connects compatible round-head lights—including the Geekoto GT200, GT250, and GT400—to Bowens-mount softboxes and modifiers.

It works across all current Geekoto GEEK MOD modifiers and can also be kept as a replacement or spare adapter. Its quick-attach design makes switching modifiers fast for studio and location work. This is an adapter, not a standalone light modifier.
