This package contains two smart LED bulbs from Philips Hue. These bulbs feature both white and colored light and can be controlled remotely, emitting focused beams of both white and colored light. They are ideal for creating focused lighting but can also be used as a primary light source. Both RGB colors and white light can be adjusted to your preferences. The white light ranges from very warm white (2000K) to cool white (6500K) and provides a maximum brightness of 350 lumens. They consume only 4.3W to produce this lighting. You can use Bluetooth or the Zigbee protocol to operate the smart bulbs. A Bluetooth connection has the advantage of being direct and requires only the Philips Hue Bluetooth app (for iOS or Android) on your smartphone or tablet. In addition to the Philips Hue app (for iOS or Android), the Zigbee connection also requires a hub, such as the Philips Hue Bridge, which converts your WiFi network signal into Zigbee signal. The advantages of this connection are that you can connect up to 50 light sources and automate them using schedules. The bulbs can also be controlled by voice commands using Google Assistant or Amazon Alexa.
