Using 12VDC spotlight charger on LED's? Answered
I have an old rechargable spotlight that I never use, so I figured I would use it for parts. Could I use the charger 120VAC/12VDC to power some LED's, like if I wanted to make an under the counter light?
If so, would it be better to run the LEDs parallel or in series? I was reading an instructable on beginning LED's and saw that series will divide the 12 volts to each LED (4 LEDs at 3 volts each), and running parallel will send the entire 12 volts to each LED. Would I use resistors even if I ran the LED's in a series? If I ran the LED'S parallel, would the follow crude schematic be correct?
