Hi,
I have a pretty simple circuit in mind of 6 IR-LEDs in series, and a ballast resistor, powered by a 12v wall adapter that will generate a generous amount of current for the LEDs. My question concerns the wall adapter. In the very site that sells it, it admits that the wall adapter is variable and needs to be plugged into a regulator on the breadboard before use. Additionally, some sites seem to sell power supplies that are "regulated" https://www.jameco.com/z/GS06U-4P1J...g-Wall-Adapter-15-Volts-0-4-Amps_1940707.html.
The solution is simple enough if my Wall Adapter needs regulating:

So do I regulate my wall adapter or not?
