flickering flameless candles combine a 3D wick with waterproof feature to make the outdoor candles more realistic without worrying about melting, rain, hot or cold weather. Ideal for indoor and outdoor use. To balance practicality and aesthetics, our designers have done a waterproof treatment on the top and base of LED candles, slanted design prevents rainwater from accumulating on the wick, achieving an IP55 waterproof rating. Battery candles retain the 3D wick and ivory plastic casing, which is more transparent when the light is on. You can control electric candles remotely when placed in a hard-to-reach place. Set a 2H/4H/6H/8H timer to save yourself the trouble of manual operation, as they will automatically turn on and off at the same time every day. You can also adjust the light modes (flickering/steady glow) and the brightness as needed.
