How to choose the right color temperature for LED lamps?
Now there are various color temperature household LED lighting equipment on the market, such as warm white, true white, natural white, cool white, warm yellow, sunlight, etc. When customers choose lamps, it is often difficult to understand what these terms represent. What kind of light, whether it is what you want.
In the industry, the United States and many countries have put forward strict performance requirements for LED lighting applications. In 2007, the first industry policy was introduced: "Energy Star Program Solid State Lighting Requirements". The 2010 document follows: "Energy Star Program Integral LED Lighting Requirements." Each document contains requirements for correlated color temperature, color rendering index, lumen, and color maintenance for ENERGY STAR-approved LED lighting products, and has since been revised. The correlated color temperature requirements are summarized in Tables 1 and 2. There are only four color temperatures for home lighting, 2700K, 3000K, 3500K and 4000K, which means that this is an industry standard. And starting from 5000K is limited to commercial use.
In fact, the lamps we use in our daily life mainly have three color temperatures, warm white, natural white and positive white. After reading the pictures below, I believe you already know how to choose.
