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. After you have finished shopping request total for all purchases,
you will then receive a invoice with the discounted S&H. If there are
any questions we are always more than willing to help if possible.
