It is better to keep the filaments away from reach of sunlight to avoid from deterioration of colors. Remember to keep the filaments in a sealed bag with silicon desiccant (The beauty of silicon desiccant or silica gel is the physical adsorption of water vapour into its internal pores. There is no chemical reaction, no by products or side effects. Even when saturated with water vapour, silica gel still has the appearance of a dry product, its shape unchanged. It is usually in the form of crystal balls in a sachets with pores kept with the filaments in sealed bag which has property to adsorb.)
This type of storage is one solution to avoid filament deterioration.
