Neopixel

A certain type of hyper-realistic lightsaber one of which has LEDs inside of it throughout; this type is different to the less expensive counterpart: RGB sabers RGB sabers are purely baselit which leads to a less bright blade. The neopixel is made of 2 main parts: "The Hilt", and "The Beam". The hilt is the part that you hold, the beam is the part that projects from said hilt (again, typically LEDs in a hollow polycarbonate stick).
