Hey guys, Greg here and yeah, i am about to build my first saber and i am a little confused about the resistors...
I am using a NBV3 and a 18650 3.7V aswell as a Tri Cree RRW. So first, my question i found a lot of different opinions abou this, but in the end i couldn't get smart out of it. So: should i wire the two red leds with one resistor? Because now, I came out with 1.11 ohm 1.11 watt for 1 red equals rounded up: 2x 1.2 ohm and 2/3 watt resistors. And now for the white FoC led: 0.55 ohm and watt equals: now another question should I round up to 0.6 ohm 1w/2w or 1 ohm 1w. Thank you for your advice.

Greg :)

Good practice is to resistor each LED. So 1.2ohms on each red and as White is FOC it is only briefly lit so 0.5 ohm would be ok but 0.6ohm will not be noticeably different. Again, it is good practice to round up resistor values.
