It is best not to install 3000k-4000k warm lighting in restaurants, which will make eating more appetizing and emotional. In the bedroom, we generally choose a lamp with a color temperature of 2700k-3000k, which is soft and not dazzling, and helps to relax before going to bed; The kitchen is a place that needs hands-on, and the color temperature of 5500k-6500k is bright enough for people to have a better line of sight operation. If you are worried that so many types of lamps can't be bought at one time, you can go to the offline stores of well-known domestic lighting brands, such as Sanxiong Aurora, which has wiring in more than a dozen cities across the country and can be purchased in the store.
