Due to the many types and specifications of LED light strips, many people often cannot distinguish some terms related to light strips, such as 5050 and 3528. Corresponding to this phenomenon, the following five commonly used specification terms for LED strip lights are described.


1.LED Size:

0603, 0805, 1210, 5050 refer to the light emitting elements used in LED strips ,LED sizes (English / metric), below is a detailed introduction to these specifications:


0603: Converted to the metric system, it becomes 1005. This means that the LED element is 1.0mm long and 0.5mm wide. The industry abbreviation is 1005 and the English system is called 0603.


0805: Converted to the metric system, it becomes 2125. That is the LED component is 2.0 mm long and 1.25 mm wide. The industry abbreviation is 2125 and the British system is called 0805.


1210: Converted to the metric system, it becomes 3528. This means that the LED element is 3.5mm long and 2.8mm wide. The industry abbreviation is 3528 and the British system is called 1210.


5050: This is the metric system. That is, the LED component is 5.0mm long and 5.0mm wide. The industry abbreviation is 5050.

2. Number of LED lights:

One of the characteristics of the LED Strip is the number of LED chips. The number of LED chips will affect the brightness of the LED light bar. In the market, 30 to 60 LEDs can be found in one meter. If the number of LEDs increases, the distance between the LEDs will be shorter. Some manufacturers put two rows of LEDs on a light strip, increasing the number of LEDs and light output at the same time. Increasing the number of LEDs will increase the total amount of light, but it will also increase power consumption. So choose according to your needs.

3. IP Protection:

We often see the numbers IP65, IP67 and IP68 when buying light strips. What is the difference between them?


The first number after IP indicates the foreign body protection level, and the number ranges from 0 to 6; the second number represents the waterproof level, and the number ranges from 0 to 8. Therefore, IP65, IP67 and IP68 are protected by the highest level of dust protection. The difference between them is the waterproof level.


IP65: Moisture-proof, can be used in corridors, kitchens and other indoor places. Do not immerse the IP65 LED strip in water.


IP67: Can be used outdoors, can be immersed in water for a short time, and cannot be used underwater for a long time.


IP68: Completely waterproof, can be used underwater for a long time.

4. Color Temperature:

Refers to heating a standard blackbody. As the temperature rises to a certain level, the color begins to change from dark red to bright red, orange, white, and blue, and gradually changes. Just as the color of a particular light source is the same as the blackbody, the absolute temperature of the blackbody at that time is called the color temperature of the light source.


Generally, color temperature is not used as an indicator for evaluating LED light strips, but many customers require special requirements for their environment.


The color temperature of the light source is different, and the color of the light is also different.


The color temperature is 3300K or less, and the pale colors are reddish and warm. It has a stable atmosphere, a warm feel, and a so-called warm color temperature.


The color temperature is between 3000 and 6000K, and it is called "neutral" color temperature because it has no particular visual psychological effect and feels refreshing.


The color temperature is over 6000K, and the pale colors are bluish and feel cool. It is generally called the cold color temperature.

5.Degree: cd (candela)

Candela, the basic unit of luminosity, is one of the basic units of the International System of Units.


In general, different colors of strip light have different luminosity, and the common unit is mcd, which is the candela of the room. The higher the value, the higher the luminosity. In other words, it will be brighter. This is an important indicator for assessing the brightness of LED tape light, and the higher the brightness requirement, the higher the price of the strip. This is because high-brightness LED chips are expensive, and the higher the brightness, the more difficult it is to package.



6.Emission Angle:

This refers to the emission angle of the LED component on the LED strip. Generally, general purpose SMD LEDs, or SMD components, have an emission angle of 120 degrees. The larger the emission angle, the better the astigmatism effect, but the relative brightness of the light also decreases. The emission angle is small and the light intensity is increased, but the illumination range is narrowed. Therefore, another important indicator for evaluating stip LED lights is the emission angle.

7. Voltage:

This refers to the input voltage of the LED strip. Commonly used specifications are DC 12V, some 24V.

LED strip lighting are now used in a wide range of fields, including home decor, streets, park beautification, bridge decor, billboards, and other places where light strips are common in our daily lives. It has been. As people's demand for beauty continues to grow, the use of LED strips will become more and more widespread.
