Using these LED votive candles is a breeze. First, check if the included CR2032 button - cell battery is properly placed inside the candle. Then, simply turn the on/off switch at the bottom to the 'on' position, and the warm white light will illuminate. When the light starts to dim after about 50 hours, you can replace the battery with a new CR2032 button - cell. Since these candles are not waterproof, keep them away from water to avoid damage. To clean, use a dry cloth to wipe off any dust or dirt. Enjoy the cozy atmosphere these candles bring to your space!
