How do I choose the correct power supply?

Depending on the power and length of the LED strip, you will need a particular power supply. There are a variety of these available: 10, 20, 30, 45, 60, 80, 100 and 150 watts.

To select the right power supply, calculate the length of all the strips and multiply this number by the strip power per metre (watts). Then, add an additional 20-30% reserve to the result.

For example, we have five metres of LED strip with a power of 14.4 W per metre. This strip requires a transformer with a power of at least 14.4 x 5 x 1.2 = 86.4. Therefore, in this case, we would choose a 100-watt power supply.
