Neopixel lightsabers have hundreds of super bright, colorful LED strips inside the blade itself, making the lighting effects superior and realistic. They also have cool animations like blaster deflections and smooth real jedi style film effects.RGB lightsabers have an LED in the hilt, which lights up the whole blade. They’re not as bright as Neopixel, but they’re more durable and better for dueling, They also weigh less which is great for spins!In short: Neopixel is for amazing effects and brightness and the true Jedi experience, while RGB is great for durability and dueling!
