Common problem: 1.Why the end of LED strip looks like red or yellow when you light up maximum brightness White Light ? A1: It is better to add DC12V voltage every 16.4FT, because the LEDs at the far end of the strip might be dimmer due to the added resistance and voltage drop that occurs as the current flows to that end of the strip. 2.Why do I light up a few LEDs ? A1: Please make sure you using the right power supply . For this LED strip , it is DC12V. A2: The controller is defective . Please make sure the controller can work fine . 3.What are the functions of the two extra wires on two ends ,one is white ,one is red ? A1: They are using to connected the DC12V power supply when the LED strip out of voltage . So we also call them voltage adding wires . 4.Can I connect them in series when I want to control 4 reels of them ? A1: Yes , they can end to end connct many reels .
