Led strip light voltage drop test 12v 24v and longer cable with led strip light voltage drop test
Article Name
Led strip light voltage drop test 12v 24v and longer cable with led strip light voltage drop test
Description
Led strip light PCB is make by copper. As we know , copper have electrical resistivity. That means when we use the pcb longer , then the voltage will less in the end than in the beginning.Many customer will have the question , How long can we use the led strip light ? How is the voltage drop in the end of 5 meter led strip light ? Does DC24V voltage better than DC12V ?How long can I connect the led strip light ? How long can I use the cable from the driver to led strip light?

Led strip light PCB is make by copper. As we know , copper have electrical resistivity. That means when we use the pcb longer , then the voltage will less in the end than in the beginning.Many customer will have the question , How long can we use the led strip light ? How is the voltage drop in the end of 5 meter led strip light ? Does DC24V voltage better than DC12V ?How long can I connect the led strip light ?

In this post we will make a test.

1,DC12V Led strip light voltage drop test

2,DC24V Led strip light voltage drop test

3,Long cable with led strip light voltage drop test

1,DC12V Led strip light voltage drop test

led strip light voltage drop 12v test (1)

1,In the beginning of the led strip light .The Voltage is 12.54V

led strip light voltage drop 12v test (2)

2,In the end of 5 meter of the led strip light .The Voltage is 11.5V

led strip light voltage drop 12v test (3)

3,In the end of 10 meter of the led strip light .The Voltage is 9.92V

led strip light voltage drop 12v test (4)

4,In the end of 15 meter of the led strip light .The Voltage is8.9V

led strip light voltage drop 12v test (6)

5,15 meter DC12V led strip light test

2,DC24V Led strip light voltage drop test

led strip light voltage drop 24v test (1)

1,In the beginning of the led strip light .The Voltage is 23.8V

led strip light voltage drop 24v test (2)

2,In the end of 5 meter of the led strip light .The Voltage is 21.7V

led strip light voltage drop 24v test (3)

3,In the end of 10 meter of the led strip light .The Voltage is 18.8V

led strip light voltage drop 24v test (4)

4,In the end of 15 meter of the led strip light .The Voltage is 17V

led strip light voltage drop 24v test (5)

5,15 meter DC24V led strip light voltage drop test

12V Voltage Drop Test
Begining/V5Meter/V10Meter/V15Meter/V
12.5411.59.928.9
-8.29%-20.89%-29.03%
3led/unit (every led voltage)
-2.76%-6.96%-9.68%
24V Voltage Drop Test
Begining/V5Meter/V10Meter/V15Meter/V
23.821.718.817
-8.82%-21.01%-28.57%
6led/unit (every led voltage)
-1.47%-3.50%-4.76%

From the test report , we know DC12V and DC24V ,the voltage percentage in the same length is almost the same . But we can see , the DC12V led strip light is 3 led/unit , and DC24V led strip light is 6led/unit.Then means the same voltage drop , DC24V voltage drop for every LED is only half percentage voltage drop of DC12V. So if you use longer led strip light , we suggest use DC24v led strip light.

3,Long cable with led strip light voltage drop test
