Products whose codes end with a “C” are seamless at any length, while those without a “C” have a visible 1mm seam every 24” (610mm) in the roll direction.

DF90C is a double-sided diffusor and can be installed in any orientation; all other diffusors are directional and should be installed with the microstructures (textured side) facing away from the lamp.
