LED Power Source for Shelf Mod?

Question

I'm attempting to put LED's on the top level of a shelf that to make it look more interesting, the problem is that for a power source, (the few ways I have seen them done) are always battery packs.
Is there a way that instead of having to perpetually replace batteries, just wire the LEDs so its powered by a household socket? Any input would be great im pretty new to this LED stuff. Thanks!

Answer 1

You could just use rechargeable batteries.
