2x4mm LEDs (10)
Pack of 10
- Red, Yellow, Green and Orange Led's works on 1.8 to 2 volts
- White, Blue and Purple need 3 to 3.5 volts for proper operation
- All 2 X 4mm LED's operate on 20ma. A current limiting resistor should be used when lighting LED's in most applications. To find the correct resistor subtract led working voltage from your source voltage then divide by .02, use a resistor equal to that amount or greater, do not use a smaller resistor.
