    Not sure if this will work, thats i am asking here.

    Instead of hooking your LED's, or Grain-of-wheat bulbs to your AC power pack.
    Would i be able to something like this?

    A 9v battery hooked up to a on/off switch, then to my LED, or Grain-of -wheat bulb?
    If i can, would this be a waste of time?

    CAS: It should work for a 12V GOW bulb, but you'd need a resistor for the LED (or a lot of them in series). A regular battery (1.5V AA to D size) would be a better match for the LED.
    However, battery is the expensive way to buy electricity. Wall warts (wall mounted transformers) would probably be more economical in the long run, and they can often be got for the asking from someone with old computer equipment.
