    exhumed07 If you have a bundle of these l.e.d s, as stated, just to prove that all will be O.K, just join, by any means, all the REDs together,and put a 200 ohm resistor in series with them to the Positive (16v+supply), and then join all the Black leads together ,(no resistor) and take to the...

    exhumed07 To simplify ; Join all your Red (positive) leads together and the same with the Black (Negative) ,Put a 200 ohm resistor in series with the Red lead , attach your 16 volts dc,and switch on.. As Electron Works, pointed out , this is a nominal value, assuming 20- 25ma of current, and...

    exhumed07 First of all regarding your statement, 'you know ohms but not resistors.'. Well you really need to learn or have a copy of the 'The Resistor Colour Code' In this query you refer to 200 ohms ,which in the colour code equates to Red,Black,Brown. Now, I am not sure just how many L.E.Ds...

    Hi nice to see someone who will have go with the 'soldering iron.. First I would ask, the voltage referred to, 16v,as against the required 12v.. Is this measured 'on load' (connected) or just the floating (un connected) voltage.. The l.e.d 's, you say; already have the appropriate limiting...
