Question about Led's
Recently I took apart one of those dollar store led flashlight's. There is 5 led's in it . all the + anode were connected to each other and all the - cathode were conected to each other and they were conected to 4 button cell batterries no resister or any thing else does that mean that each led runs on 6 volts and as long as I use a 6 volt dc battery they should work fine without a current limiting resistor and if I run them in series I could use 12 volt battery. the led's look white but they give off a blue light?
