How to Select a PSU for your LED Strips

LED strips are very easy to use, but you need to make sure the power supply has sufficient capacity for the length of LED strips being used. As all the colours of LED strips take about 400 mA per meter, the longer the length of strip the bigger the power supply has to be. To save you doing the maths below is a table showing the maximum length for each of the power supplies. The highest power option is a wall mount power supply which is good for fixed installations of a couple of reels of LEDs.

Max length	Power supply	Code
1.25m	12V, 500mA, wall plug PSU	2260
5m (1 reel)	12V, 2A, wall plug PSU	2266

  The LED strips are available in a range of colours either as a half meter length or a full 5m reel.   Download a pdf version of this page here Learn more about the author read more »
