What is the knowledge about LED light string?

LED light string is a light string made of lamp beads, circuit boards, and PVC raw materials.

Number of lamps:
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 has 60 LEDs per meter, and the 5050 specification light strip has 30 LEDs per meter. There are 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 light strips.

Color temperature:
It refers to heating a standard black body. When the temperature rises to a certain level, the color starts to change gradually from dark red-light red-orange-white-blue. When a light source has the same color as the black body, we call the absolute temperature of the black body at that time. is 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:
When the color temperature is below 3300K, the reddish light color gives a warm feeling; there is a stable atmosphere and a warm feeling. It is commonly known as 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.
