I want to buy this inexpensive LED moonlight fixture off amazon but it states something about not coming with a power outlet. It also says something about it being dc. My question is when you buy LEDs like these, how do you power them? Do I need to go to home depot and buy a circuit or something for it?
 
Also, my other question is what is a transformer? Is it a something you plug the LEDs into?
