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.
