Wiring Schematic Critique?

[Forgetful Jedi Knight]

If you are using a Cree as the main LED, then you'll be fine.

[Robust Stardust]

If he "rounds up" as I suggested, a 1 Ohm, 1W would work even at 700 mA.

But now that I look at it again, the Vf for that Deep Red looks pretty high. it should be more in the 2.3-2.4V range IIRC.

Ah yes, quite right! That Vf of the deep red Rebel would put the resister in the realm of a 2 ohm 1 watt resistor, if I'm not mistaken.
And like you say, a Cree would be the most elegant solution in this case, resistor-wise.

Sorry, I guess I'm throwing some confusion here. My current build is my first saber, which will have a white blade and crystal chamber.

I am planning a second build with a red blade and crystal chamber, so I may have accidentally linked to that. However, this thread is strictly about my first build (white blade/crystal).

Oh, my bad! Please disregard my correction for the Rebel's amperage (although it might come in handy for your second build with the red Rebel!). Best of luck
