18º Grid Spot Attachment

  • over-mounted 18º honeycomb grid for the 7-inch reflector
  • narrows the beam spread from 80º to 18º
  • for use with the 7AB/R 7-inch reflector and older, retired 7-inch reflectors
  • mounts over the outside lip of the reflector
  • 60-Day Absolute Satisfaction Guarantee
  • 1-Year Factory Warranty
The GS1 Fitted Grid Spot Attachment is designed to fit directly over the standard 7-inch reflector (either the 7AB/R, retired 7-inch reflectors or the built-in reflector on the retired White Lightning™ WL Series flash units). This built-in grid reflector will take the 80º beam spread down to a highly controllable 18º spread for a back or hair light. The attachment measures 7.375 inches square x 2.25 inches deep.

For convenience and versatility in use with current Paul C. Buff™ flash units, we recommend the HG10, HG20, HG30 and HG40 grids with the 7AB/R reflector over the GS1 attachment.

*** with the 11HG30 in the 11LTR reflector, the grid maintains the same beam spread, but eliminates light spill outside of the 28º pattern
The GS1 Fitted Grid Spot Attachment can be used with the standard 7-inch reflector (either the 7AB/R, retired 7-inch reflectors or the built-in reflector on the retired White Lightning™ WL Series flash units).

When a grid is in use, the umbrella hole is blocked and umbrellas, therefore, may not be used simultaneously.

The GS1 is not compatible with the UMF LiteMod™ Unit Mainframe and it can therefore not be used in conjunction with filters and gels or other LiteMod™ accessories.
