How to choose the proper amperage:
First, lets figure out the total amperage draw of your LEDs.Suppose you are powering 16 feet of our flxible LED Strips which use 130 mA per foot.
--> 16 feet x .130 amps = 2.08 amps
While the 2 amp AC Adapter would work for this application, it would be at the limit of its capabilities.The LEDs may not reach their full brightness potential, and the 2 amp AC Adapter may work harder than it should. In this specific case, it would be better to go with the 3.25 amp AC Adapter.
