# How many watts does a cob light strip cost per meter?

COB light strips usually range from 6 watts to 20 watts per meter.

COB light strip is a high-brightness LED light strip, which is characterized by the LED chip being packaged on a large COB (Chip-on-Board) chip. Since multiple LED chips are integrated on the COB chip, the COB light strip has higher brightness and lighting effect per unit length.

The power of COB light strips is related to the specific model, number of LED chips, input voltage and other factors. Generally speaking, the power of COB light strips can be calculated by the following steps:

Determine the power of each LED chip: Find the LED chip's specification book or technical information to find the rated power of the LED chip. Assume that the rated power of the LED chip is P_LED (unit: watt).

Calculate the total power of each COB chip: Add the power of each LED chip to get the total power of each COB chip. Assuming there are N LED chips on each COB chip, the total power of each COB chip is P_COB = N × P_LED.

Calculate the total power of a one-meter COB light strip: According to the number of COB chips per meter on the COB light strip, multiply the total power of each COB chip by the number of COB chips to get the total power of a one-meter COB light strip.

The power calculation of COB light strips is only a theoretical reference. Actual use should be confirmed according to the specifications and parameters of the specific product.

The power of COB light strips depends on the number of LED chips on each COB chip and the rated power of each LED chip. When choosing COB light strips, you can reasonably choose COB light strip products with appropriate power and brightness levels based on lighting needs and energy consumption considerations.
