Hi!
From what I've seen so far, most lightasabers use either 1 or 3 high-powered LEDs facing down the direction of the blade. While my own saber currently only exists in the design stage, I've been thinking about placing a rim of less powerful LEDs facing inwards, with a reflector in the center/focus. Theoretically it should give me a more evenly lit blade and more flexibility for different shimmer and light up effects, as well as better heat management. Does anyone here have any type of LED in mind for this kind of project?
