Pack of 25
- Red, Yellow, Green and Orange LED's work on 2 to 2.8 volts at 20 ma.
- Blue and White at 3.5 to 4 volts at 20 ma.
- A current limiting resistor should be used when lighting LED's in most applications. To find the correct resistor divide your source voltage by .02 then use a resistor equal to that amount or greater, do not use a smaller resistor.
