  • Low Current LED

    Suggest LED with following Details

    1. 3mm / 5mm
    2. Single / Dual color
    3. Color Combination any except Red
    4. It must operate from 3-5V
    5. It should operate with low current may be 0.5 - 2 ma but with good brightness

    If any one use then please inform it's make.

              Performance means ? Such low current LED's have same performance as compared to others.

                No Low current affect Intensity which important to me. Also it's voltage drop & Color is also important

                  Low Current LED

                  Use 5 volts with a 10 ohm resistor in series with LED operating at 30% duty cycle being fed from a 555 in astable mode at say at 1KHz

                    Can u use such type combination if yes inform which type of LED use means Red/Green, 3 mm / 5mm , if possible give me make & part no. so that I can test it.

                      Intensity will be directly proportional to voltage drop and current flowing, if you are looking for low current and low voltage drop - you won't get intense light output. However, you can optimize all these values to get maximum output of your choice. Usually, voltage drops are standard based on color of LED and red one will have lesser voltage drop compared to others. As you don't want red LED, you will have to live with high voltage drop of approx. 2+ volts.

                        Yes I have same issue which mentioned above but due to let us innovation in market may be any new led which may use any forum member so i post this issue.

                          i got this type of led from local store but its current rating is more.

                            From where u get led having current rating ?
