Using these LED votive candles is a breeze. First, make sure the candles have the included CR2032 button cell batteries installed. Then, simply turn the on/off switch at the bottom to start the warm white glow. These candles can last up to 50 hours, but when the light starts to dim, you can easily replace the batteries. Since they're not waterproof, keep them away from water to avoid damage. To maintain their appearance, gently wipe them with a dry cloth. Enjoy the cozy ambiance these flameless candles bring to your space!
