I have ten (10) 12 volt 10 watt cob led's and a 12V X 5A power supply. I wired two rows of 5 led's in series and hooked them up to the ps. Nothing happened. All ten will light up if I wire each one individually to the ps. Can someone explain why I can't wire them in series? Also, can a dimmer be incorporated in this circuit?
