Most smart LED light bulbs are controlled wirelessly through a smartphone or tablet, usually via a Bluetooth-compatible device. Many are compatible with Amazon Alexa or Google Assistant. Wi-Fi is typically required to turn on and customize a smart bulb, regardless of where you choose to install it. This may not be the case for some bulbs, but it’s good to have a strong Wi-Fi signal in your home just in case. You should check the type and strength of your Wi-Fi network before you purchase a smart bulb, just to ensure that it’ll be compatible with your home Wi-Fi.
