These were the easiest shades to install of all of the shades my husband put up this week in our new home but I thought these shades would be more room darkening.  They stop direct light but wish these kept more light out then they do.  These should be considered light filtering, not light darkening.  If you want light darkening go with the Room Darkening Cellar Shade by Symple Stuff (those are really dark for sleeping).
