# How to wire electricity to multiple hanging paper lanterns Answered

I aquired multiple hanging paper lanterns that came with battery led lights that can be removed and I am wanting to wire them to one plugin. Can someone help me in possibly achieving that or would it be to much on one electric cord? Or another way to make them wired instead of battery powered.

I am thinking the easiest thing to do with your lanterns, assuming they are all the same design, with respect to power supply. I mean, like, for example supposing every lantern uses the same number of battery cells, and thus the same voltage, from the bottom of that stack of cells to the top.

I think the easiest thing to do would be to just wire all your lanterns in parallel, so they share the same voltage. Then connect those two wires up to one big power supply, capable of supplying that voltage, or close to that voltage, and capable of supplying enough current to fan out (i.e. 4 lanterns require 4 times as much current as 1 lantern. 10 lanterns require 10 times as much current as 1 lantern,) to all the lanterns.

The length of the wires will not be a big deal, I don't think, but then I am guessing the amount of current needed for 1 lantern is small, e.g. less than 50 mA. Also guessing the length of the wires is just a few meters, rather than a few kilometers. Also guessing you have, at most, 10s of these lanterns, rather than 100s or 1000s of them.

It is possible to calculate the (expected small) voltage drop from one lantern to the next, if we know length and size of the wire (which determines the resistance of the wire), and the current flowing through that wire. But again I am expecting the resistance in the lengths of wire to small, and likely much smaller than the ballast resistors in each lantern.

LED lights normally don't use much power.
Depending on your service voltage and the LED voltage you can have as many as 60 to 120 LEDs in series.
