TP-Link unveils KL125 Kasa Smart Wi-Fi Multicolor Light Bulb A smart home is a happy home as far I am concerned. Since going all-in on smart devices in my house, my life has been much improved. I can control my thermostat without getting out of bed, and when I leave a room, I can tell Google to turn off the light. If I hear a bump in the night, I can pull out my phone or tablet to monitor my Wi-Fi cameras. We are living in the future, and it is great. For my smart lighting, I have outlet adapters connected to lamps, and for the most part, this works well. If I could do it over, however, I would probably just get smart bulbs. Today, TP-Link unveils its latest such product; the KL125 Kasa Smart Wi-Fi Light Bulb. This 800 lumen bulb is notable for being both dimmable and multicolor, meaning you can change the color and the brightness of the light -- something you cannot do with a smart outlet adapter.
