The brightness of COB strip is related to the number of beads, chip size, current and other factors, so an accurate value cannot be given. Generally speaking, the brightness of COB strip is calculated according to the length and power of the strip. For example, a COB light strip with a length of 1m and a power of 14.4W has a brightness of about 1200-1400 lumens. However, the specific brightness needs to be measured according to the parameters of different products.

What does lumen (lm) mean in LED strip?

Lumen is a unit for measuring luminous flux, which represents the total amount of light emitted by a light source. In LED strip, lumen number is usually used to describe the luminous brightness of LED beads or the whole light strip, that is, the light intensity generated under certain conditions (such as input voltage, ambient temperature, etc.). The higher the lumen number, the higher the brightness of the lamp strip, which is suitable for scenes that need brighter lighting. At the same time, the lumen number can also help consumers to judge the energy consumption efficiency of the lamp strip, that is, under the same brightness, the lamp strip with higher lumen number is usually more energy-saving and has a longer service life. Therefore, when choosing LED strip, lumen number is an important reference index.
