Sconce
Any of a wide variety of styles and configurations of wall-mounted lighting fixtures. The defining element is that it is fixed to the wall as opposed to being ceiling-hung or table or floor mounted. Some of the most common types of sconces are: 1. Candle uplight sconces where the basic form is determined by the necessity of burning a candle. These typically have either a spike on which a candle is fixed or a cup into which a candle is inserted and often have a broad pan beneath to catch the dripping wax called a bobeche or waxpan. Both gas and electric powered fixtures have adopted this vocabulary, substituting ceramic or paperboard sleeves to simulate candles. 2. Glass-shaded gas sconces. 3. Uplights or wall washers. These are made of opaque materials to direct all their light up along the wall and ceiling and commonly take the form of shells or split bells.
