ROKOO Diwali Decor Fancy Tea Lights Candles Floating, Smokeless (Pack of 3) Candle  (Multicolor, Pack of 3)

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. 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. The wick is tethered to a piece of metal to stop it from floating to the top of the molten wax and burning out before the wax does. Tealights have been protected under several patented designs. In some cases, the standard tea light metal cup has been replaced with a clear plastic cup, sometimes made out of polycarbonate plastic. The clear cup allows more light to escape the holder. However, the metal cups are much more common.
