Tealight

A tealight (also tea-light, tea light, tea candle, or informally tea lite, t-lite or t-candle) is a candle in a thin metal or plastic cup so that the candle can liquefy completely while lit. They are typically small, circular, usually wider than their height,^[1] and inexpensive. Tealights derive their name from their use in teapot warmers, but are also used as food warmers in general, e.g. fondue.^{[citation needed]}

Tealights are a popular choice for accent lighting and for heating scented oil. A benefit that they have over taper candles is that they do not drip. ^[2] Tealights may be set afloat on water for decorative effect. Because of their small size and low level of light, multiple tealights are often burned simultaneously. Longer-burning tealights may be called nightlights. They are also lit for religious purposes.
