This is an Elinchrom Honeycomb Grid Set consisting of an Elinchrom 8.25" diameter EL 26141 standard reflector, which fits all Elinchrom flash heads and monolights, and 4 honeycomb grids that fasten to the front of the reflector. The kit comes with a barndoor adapter that will only fit this reflector, not the 65 degree version of it.
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
