The main distinctions between SN Pixel and Proffie lightsabers lies in their core technologies and emphasis on customization. SNV4 Pro sabers place a strong emphasis on visual and lighting effects, while Proffie sabers prioritize sound and interactivity. Both technologies utilize Neopixel blade strips for illumination, but Proffie lightsabers take customization to a whole new level by providing extensive control over sound fonts, lighting effects, blade hues, and motion sensitivity.
