led light question
« on: July 24, 2012, 12:19:18 »
Possibly  one of the  members can enlighten me about LED lights
I am using 6 volt LEDs .50mA and have 4 wired in parallel (I believe). I was expecting that 6 volts would turn the lights on; but this is not the case; it takes 12 volts.  Should 6 volts turn the lights on? Can someone explain what is occurring or what I should expect if wired correctly?
Thanks

It doesn't sound like they are wired in parallel. If all of the negative leads (the shorter ones) are connected together and to the negative of the battery, and all of the positive ones to the positive then 6v should light your 6v LEDs. Either that or you have 12v LEDs!

Could it be that they need suppressors?

I think you mean resistors, Barry, and you would only require those if the supply voltage was greater than the forward voltage. In this case it's the same (6v) - or so we're told.
