Question:

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?

    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.

Question:

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.

    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.
