    Answered by the admin Hi,
    Many thanks for the query.
    The forward voltage is 2.1V and we would recommend 20mA current.
    Thank you
    2. I would like to do an e-textiles product that has two flashing red LEDs. Please could you let me which LEDs I need to buy and whether or not the LEDs each need a resistor. I plan to use a 3V cell battery.Also, do you accept orders on LEA school purchase orders?ThanksJulie

    Asked by Anonymous on April 30, 2014 12:00 am
    Answered by the admin The power or wattage is just the current x voltage. So 0.025A x 2.1V = 0.0525W
