TP-Link has released three new smart Wi-Fi lightbulbs, and as with just about every smart product released this year, it's compatible with Amazon's Alexa. If it wasn't clear before, Alexa has become the default smart home integration option for the majority of smart device manufacturers.

The TP-Link LB100, LB110, and LB120 bulbs don't require a hub like its Philips Hue counterparts — they can be fully controlled through the Kasa app on Android and iOS. All three white LED bulbs connect directly to your Wi-Fi router, can be dimmed, and set on timers and schedules. The LB100 is rated at 600 lumens, while the LB110 comes in at 800 lumens.

While the LB120 is also rated at 800 lumens, it does allow you to adjust the color temperature between warm and cool as you please. The TP-Link LB100 and LB110 cost $20 and $25, respectively, while the LB120 comes in at $35. All of these bulbs are noticeably more costly than the GE Link smart bulb, which at 800 lumens matches the output of the LB110 for nearly half the price. You can purchase the smart bulbs from TP-Link's website, Amazon, and in Home Depot stores.
