As the junction heats, the forward voltage will drop or the LED leakage current will increase during the constant voltage test. These effects can impact the accuracy of the test or, more importantly, potentially damage the device under test.

WebWiring LEDs in parallel allows many LEDs to share just one low voltage power supply. We could take those same four 3V LEDs and wire them in parallel to a smaller power supply, say two AA batteries putting out a total of 3V and each of the LEDs would get the 3V they need. In short, wiring in series divides the total power supply between the LEDs.
