Edward, It is not strictly necessary for CS to be protected from light. Most light does not have the energy to photo-reduce the Ag+ particles. UV light however may have sufficient energy so to do. I have 2 x 10L plastic containers with 20ppm dc generated CS that shows no deterioration after almost 1 year, and various small soft clear plastic containers scattered about the place of greater vintage. Bob Berger who has done many tests uses nothing but hard clear plastic (PET?). This means that one can keep CS in small spray bottles etc. with no fear of deterioration.
