I tried using smart bulbs a few times but gave up because there were too many colors to choose from, and I couldn't find the right one. In the end, I said goodbye due to the hassle. This product adjusts the bulb color according to your circadian rhythm (time). It offers a color spectrum comparable to other smart bulbs, but it comes with exactly 5 default colors, which is perfect for a lifestyle like mine that hates hassle. Haha. I especially love that it measures energy consumption. These days, because of the progressive tax system, I always prioritize energy efficiency ratings (Grade 1) when looking at utility bills to cut costs, and this bulb is also Grade 1. You can adjust the color to automatically change based on theme selection or music synchronization, adding a little joy to a calm life. Additionally, you can set on/off times. Connecting to the app is also very simple. . . #SmartBulb #스마트조명 #타포
