LED-Pixel blades are made up of 256 individual LED-Pixels along the length of the blade. LED-Pixel blades are brighter than base-lit variants and have more special light effects as the light and colour of each individual LED can be controlled. Hilts that support base-lit can not be installed with a LED-Pixel blade and vice versa.
LED-Pixel blades are also known as Neopixel blades.
