Make LEDs Dimmer?
I'm decidedly not an electrical engineer. This is probably an exceedingly simple question, but my mechanically oriented mind doesn't comprehend amps, ohms, watts and what-not. I have a 12 volt 4-LED light, and I need it to make it half as bright. It doesn't have to be exact, but noticeably lower light output is required. I presume I can just wire a resistor into the positive input, but which resistor? How many watts and ohms do I need to get the job done? Sorry for the remedial question, and thanks for your help!
