Lifx Plus

Turn this smart bulb off and it'll put out invisible infrared light, lighting up the room for night vision cameras.

The Lifx Plus is bright and efficient as ever, features a well-designed, integrated and easy-to-use app. It produces bold, accurate colors at every hue. The new night vision feature is unique and legitimately cool.

Lifx bulbs still aren't compatible with Apple HomeKit. Those infrared night vision diodes mean that the Lifx Plus is always drawing power, making it less efficient than its predecessors.

If you use night vision cameras in your home, then these well-rounded smart bulbs can help them see in the dark -- but if you don't, there's really no reason to buy them.
