Noob building a tri cree stunt saber, battery questions.

[ClassicalQuack]

So, I'm gutting an US body I've worked on previously and sticking a Tri-XP-E2 with 3 deep red LEDs.
The info on the LED is
425 Radiant Flux @ 350mA
Forward Voltage @1000mA = 2.5v

Will A standard 6v 4AAA battery holder be able to generate enough juice to get these lights running?

[Silver Serpent]

They'll light up, but not well or for long. If you only wanted to use a single LED on your star, you could do it with just 2 alkaline batteries (3v). AAA batteries won't provide enough current to drive all 3 LEDs properly. You'll want a li-ion solution. A single 18650 cell will do the job just fine.

[ClassicalQuack]

Alright, I'll go the 18650 route. Thank you! I'll just figure out what resistors I need and should be golden. I'll need one for each led, correct?

[Silver Serpent]

That is what we generally recommend.
