Abstract: Embodiments of the disclosed technology are directed to devices and/or methods for securely engaging a candle-holding receptacle or oil lamp within a candle holder. The devices and/or methods may employ a candle holder interface which is formed of a unitary body having male and female ends, with a flange there-between. The male end is adapted to be inserted into a candle holder. The female end is adapted to receive a candle-holding receptacle or oil lamp. The interface securely holds the candle-holding receptacle or oil lamp within the candle holder and/or catches any excess oil that drips from the burning portion of the wick.
