The Chimera video pro polycarbonate speed rings offer a great budget-friendly option for mounting lightbanks to your smaller continuous lights. With a matte black polycarbonate outer frame, these speed rings have four pole sockets to support chimera's video pro and lantern lightbanks. The outer frame smoothly rotates 360°, independent of the light-specific metal insert giving you control over lightbank placement. polycarbonate speed rings are suitable for lights up to 400W. For higher wattage lights, chimera's aluminum, quick release, or OctaPlus speed rings are recommended.
