The disadvantages of this type of light are that they collect dust, the chain collects dust, and the hooks to hold the chain has to be very, very secure. The advantage is that the light source in a room is suspended. Light can pour into a room without a fixture taking up space like a table lamp or a floor light does.
More modern hanging light
Check in local electric supply stores for a wider selection of hanging lights than one finds in the big box retailers' lighting departments. Local and family-owned lighting stores also have access to extensive catalogs of fixtures that can be ordered from the lighting manufacturers. In general, fixtures from American manufacturers are typically more suited to decorating an old-fashioned American home.
