WebTo work out how much LED tape you can run off an LED power supply, simply divide the wattage of your LED strip driver (for example, 100w) by the wattage per metre of your LED tape (e.g. 4.8w p/m). This gives you the total length of LED tape, in metres, that your LED power supply can drive. So in this example…. 100w divided by 4.8w = 20.83m. WebMar 31, 2013 · LEDs, being diodes, will only allow current to flow in one direction. And when there's no current-flow, there's no light. Luckily, this also means that you can't break an LED by plugging it in backwards. Rather, it just won't work. The positive side of the LED is called the "anode" and is marked by having a longer "lead," or leg.
