Floating Water Design: This electronic candle is designed according to the law of buoyancy, meaning it does not sink in water but floats on the water surface, providing waterproof functionality. This offers advantages over ordinary burning candles or other electronic candles, which cannot be placed in water. Liquid Detection: No switch – The candle has two sensors on the underside that detect liquid. When they come into contact with water, the candle automatically lights up, and the induction is very sensitive. Place the candle in the water or on a tray with water, and the candle will light up. There is no switch to turn it on or off. Remove the candle from the water when not in use. High-Quality Materials: The candle comes with a CR2032 button cell battery, which surprisingly lasts up to 60 hours (with 4 hours of use per occasion, it can be used 12 times). Enjoy the romantic atmosphere it creates for a long time. The protective casing is made of high-quality polypropylene, lightweight, scratch-resistant, and easy to carry and store. Safe and Worry-Free: No flame, no smoke, no risk of burns. No unpleasant odor, no burning dust, and you don't have to worry after use. (Batteries can be recycled and reused.) Realistic Flame Effect: The lamp's design resembles a flame. The light mode is warm yellow and flickers, making the effect at night as romantic and warm as a real candle. Suitable for various scenarios, such as wedding parties, family gatherings, corporate parties, events, pool clubs, and so on. These warm white candles will surely be the centerpiece of your beautiful evening. Description: Unlike ordinary electronic candles, this one floats on the water surface, making your usage situations even more romantic. No manual switching is required; the light is activated automatically when placed on the water and turns off automatically as soon as you remove the light from the water. Safe and environmentally friendly, no flame, no odor, and recyclable. Note: This product can float on water but must not be submerged. If the light is submerged, this can damage the internal wiring. After 48 hours of use, the light will gradually dim. Replace the button cell battery in time. If it is not possible to manually unscrew the bottom of the battery, use the clip to secure it and loosen the screw. After each use, remove the tealights from the water and wipe away the water to prevent rust formation on the bottom sensor and battery (very important).
