Ever wondered why tea lights are so called?
A tea light also called tealight or nightlight, is a candle encased in a thin metal or plastic cup so that the candle can liquefy completely while lit. They are typically small, circular, wider than their height and inexpensive. Because of their small size and low level of light, multiple tealights are often burned simultaneously.
A tea light derives it’s name from their use in teapot warmers, but are also used as food warmers in general, e.g. fondue (anyone remember them!)
Tealights can come in many different shapes and sizes, small and large, as well as burn times and scents. However, the most common tealight is 38 mm diameter by 16 mm high, and made with white unscented wax.
A standard tea light has a power output of around 32 watts, depending on the wax used, and typical burn time can be anywhere between 3-5 hours.
