LED strip light how many watts per meter

The power of one meter of light strip is between 10 watts and 20 watts, depending on the number of lamp beads. Taking ordinary lamp beads as an example, the power of each lamp bead is about 0.2 watts to 0.3 watts, assuming that the number of lamp beads per meter is 50, the power of that meter is 0.2 * 50 = 10 watts. Different LED strips are different, and they need to be calculated according to their current and voltage to calculate the power. Power is a measure of the rate of transmission of energy, and in DC circuits it is the product of voltage V and current A; In communication systems, it's much more complicated. Whether it is high-voltage or low-voltage LED strip lights, they convert AC to DC to work.

LED strip power calculation method:

White light (single lamp bead example) LED working voltage (U): 1.8V-3.6V (mainly determined by the chip, different colors, different working voltage)

Rated current (I): [one wick 10mA-20mA]

Power (P) :P = UI is the maximum power: 3V*20mA=3V*0.02A=0.06W (1A=1000mA)
