With the PLAYBULB Candle Pro Smart Bluetooth Light, you can have the benefit of a candle without the fire hazard. This compact smart light gives you access to nearly 17 million color choices through its app. You can set the ideal atmosphere for any situation, creating a warm, candle-like feeling without the flame. And it acts like a candle because it has a sensor on top that turns it on or off when you blow on it. To randomly change the color of the flameless candle, shake your phone when the app is open or gently tap the smart light. The PLAYBULB Candle truly mimics the real thing when you turn it upside down. Acting as a candle holder, it supports special effects like flickering, fading, flashing, and pulsing. If you want to spread the atmosphere around your home, simply link up to five of these compact flameless candles together.
