WebLight Source: LEDs are the size of a fleck of pepper, and can emit light in a range of colors. A mix of red, green, and blue LEDs is sometimes used to make white light. Direction: LEDs emit light in a specific direction, reducing the need for reflectors and diffusers that can trap light. 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.
