Lighting is able to change the whole concept of an environment. When properly used, it provides comfort and efficiency, but misuse can devalue space. To avoid any mistake when choosing lighting, you can analyze the color temperature. This information is measured on the Kelvin unit (K) and it is described on the packaging of the lamps. The measurement scale for the unit ranges from 2700 Kelvin (warm light) to 6500 Kelvin (cold light). According to the color temperature, warm tones refer to the tranquility and they are indicated for rooms and bedrooms, meanwhile temperatures with cold lights are indicated for rooms that require attention, such as work areas and kitchen.
