    Q Will two AA batteries be sufficient to light this?
    Asked by Martin Gilfillan on July 8, 2019 12:00 am
    Answered by the admin Hi Martin,

    Thank you for your question that should work as the LED runs from 2.8V to 4.5V and 2 x AA would supply about 3V so should be fine.

    Best Regards

    Asked by Tony Fellows on March 31, 2017 12:00 am
    Answered by the admin Hi Tony, The issue with connecting these to a supply voltage higher than 5V and then trying to limit this using a resistor is that the LED works by turning on different amounts of red, green & blue LEDs therefore to get red just the red LED is on to get purple the red and blue LED are on. This means that the current consumption of the LED when purple will be twice the current of the red as twice as many colours are on. The way you would normally work out the current limit resistor is to look at how much current the LED takes and the voltage that would drop across the resistor, the issue is that whilst there would be 4V over the resistor the current is variable. This means that you can’t work out what the value of the resistor using theory. The better option is to use a 5V regulator to drop the 12V’s down to the 5V supply that these LED’s can handle.
    3. If i wire these in parallel to your usb power cable (https://www.kitronik.co.uk/4101-usb-power-lead.html) would i need a resistor and if so which is best?

    Asked by Sam on September 22, 2016 12:00 am
    Answered by the admin Hi Sam, The colour changing LED’s are rated to 5V’s so you wouldn’t require a resistor for these. In terms of putting them in parallel you would need to make sure that you have enough current to supply the LED’s. Each LED takes between 20-25mA, and some of the colours can take up to 50mA’s.
    4. I would like to wire 40 of these in parallel for use as Christmas tree lights but I am not sure about the viewing angle.

    Asked by Andrew Noble on April 21, 2014 12:00 am
    Answered by the admin The viewing angle is 30 degrees. Just be aware that if you are using 40 of them then you will need at least a 1A power supply.
