How to test led strip. On a set of led strips i salvaged there are actually test points that are just openings in the solder mask. The brightness of the led while you test it will also indicate its quality. Led tv light tester. After adjusting the output voltage on your led power supply you can now re test the input voltage at the beginning of your led lights.

The driver primary 230vac and the secondary says 12v 416ma max 5w. Switch the polarities if it doesn t seem to be working. I want to test the led strips. For this one requires a multimeter and of course the led to be tested.

Then check the led strip itself which will have its input voltage marked at the led strip connection points. A quick test using a multimeter to verify the voltage across the two output wires or voltage between the dc plug s inner pin and outer barrel should indicate a voltage differential.

Be certain to test voltage on all your led strip lights optimal voltage is or 0 75v. After adjusting the trim pot my voltage to my led strip light is now 12 15vdc which is much more acceptable than 10 9vdc.
