First, we need to know that LED strip lights are low voltage devices.You can not connect them directly to AC110V or AC220V.That will damage the LED strip light and let your devices catch fire.You should use a led power supply that output is DC12V or DC24V.
Another thing to watch out for is polarities. There are two types of poles: a positive (+) and a negative (-). You need to make sure the LED strip light positive connection to the driver is positive and a negative connection to the driver is negative. Wrong wiring will not let your strip light lighting.
