Well since I did decide to go with the experiment, here's one question. Is it worth going with RGB or better to start with single-color LEDs? I'd like the flexibility Of RGBs, sure, but I see that...

Don't get me wrong, but I'm sure that a car's headlights and a lightsaber's blade lights serve a fairly different purpose,the first having to illuminate everything to a certain distance and the other...

Why exactly do I want a directional light? I want to illuminate the whole blade, not just the tip, or am I missing something?
How exactly does "apparent brightness" affect anything, if we are not...

I'm thinking about some flatter (not cylindrical) LEDs, I believe some of the more powerful models have the heatsink on the bottom. But again, "what kind of LEDs" was my question here. I'd probably...

Thanks by the way, FJK.
Also, I'm not adding an extra heatsink here. The heat is drained straight into the emitter.

Sorry for the long wait, forum stopped notifying me for some reason.
I meant something like this (reflector shape not final):
17570

The reflector is located fully inside the hilt. Nothing goes into the blade itself.

Sorry if it wasn't clear the first time, I'm asking about the LEDs themselves, not controllers or drivers.

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...
