This is an Elinchrom Honeycomb Grid Set consisting of an Elinchrom 21cm diameter reflector, which fits all Elinchrom flash heads and monolights, and 4 honeycomb grids that fasten to the front of the reflector.
Each grid produces its own narrow field spread of light of 8,12,20, or 30°.
Grids are essential accessories for any lighting system. Consider a grid as a painter would a brush, or a sculptor would a knife, or chisel. Suggested uses include hair lighting, background lighting, or product highlighting.
A grid alters the shape and intensity of the light output from your light.
