Two main types: traditional paraffin-wax (flame) tealights and battery-operated LED (flameless) tealights, both commonly available in orange.
Flame orange tealights use a wick and wax as their fuel source. Battery-operated orange LED tealights use small button cells (commonly CR2032 lithium batteries).
Trim the wick to about 1/4 inch before lighting and as needed between burnings. Wipe or spot-clean the candle surface if dirty, and allow the candle to cool before trimming or relighting.
Battery-operated orange tealights usually have an on/off push button or switch on the base; press to turn them on or off. They are reusable and designed for multiple uses.
Orange tea lights are intended mainly for indoor use and are commonly used on tables, mantels, table settings, parties, events, and everyday home decor—either on their own or in clear glass holders.
