Cutting and re-wiring X-mas LED garlands (not strips) Answered
Has anyone had to deal with cutting LED Christmas garlands into shorter pieces and then rewiring-powering them?
What should I keep in mind when doing so?
As far as my electrical knowledge goes I should first inspect the voltage which is provided by a standard converter already on a garland and then measure the voltage with the load (garland) on in several spots to determine a single LED voltage drop. Then cut the garland to desired lengths and power it with appropriate converters. Is this right?
What I don't understand completely however is the voltage drop. Given that this is a series circuit and the voltage(resistance) sums up - should I add all the single LED drops to find out the total drop and therefore subtract that from my supply voltage to find out the LED working voltage?
Oh, and maybe I am simply wrong about the circuit being in series?
