2. Number of LED lights: 15 lights, 30 lights, and 60 lights refer to how many LED components are welded on the length of the LED light strip per meter. Generally speaking, the 1210 specification light strip is 60 LEDs per meter, and the 5050 specification light strip is per meter. 30 LEDs per meter, special 60 LEDs per meter. The price of LED light strips with different LED quantities is different, which is also an important factor to distinguish the price of LED strips lighting.
3. Color temperature: refers to heating a standard blackbody. When the temperature rises to a certain level, the color begins to change gradually from dark red-light red-orange-white-blue. The absolute temperature is called the color temperature of the light source. Generally speaking, the color temperature is not an indicator for evaluating LED strips, but many foreign customers will make a special requirement because of the use environment. The color temperature of the light source is different, and the light color is also different: the color temperature is below 3300K, and the light color is reddish, giving a warm feeling; there is a stable atmosphere and a warm feeling. It is commonly called warm color temperature. The color temperature is in the middle of 3000–6000K. People have no particularly obvious visual and psychological effects under this color tone, and have a refreshing feeling; so it is called “neutral” color temperature. The color temperature exceeds 6000K, and the light color is bluish, giving people a cool feeling, commonly known as cool color temperature.
Fourth, brightness: cd (candela) is the basic unit of luminous intensity, and candela is one of the basic units of the International System of Units. Generally, different colors of LED strips will have different luminous intensities, and the commonly used unit is mcd, that is, millicandela. The higher the value, the greater the luminous intensity, that is, the brighter. This is an important indicator for evaluating the brightness of LED strips. The higher the brightness requirement, the more expensive the strip. This is because high-brightness LED chips are expensive, and the higher the brightness, the more difficult it is to package.
