Rebuild with Tri-Cree

Several years back I built a Tri-Rebel GGW on a NanoBiscotte platform with FoC and...long story short, I need a new LED and want to switch to a Tri-Cree GGW. Since it's been almost ten years, I want to make sure I'm not messing up my calculations and which resistors I'm ordering.

Using the 3.7 battery voltage:

Green LEDs - 3.7v at 1 amp = no resistor? I seem to recall always needing one, so would something tiny like a 0.1 ohm resistor be best?

White LED - 3.15v at 1 amp = 0.55 R

For wattage ratings, I had the formula for P = [(Vsupply - Vload) * amps ] in my original wiring diagram but I came across one today on another part of the forum that it was just Vs * amps...so I'm not sure about that.

Going with the old formula I had, that would put me at (looking at the options on TCSS):
- 0.1 ohm 1 w resistor for each green
- 0.5 ohm 1 w resistor for the single white


Can anyone confirm if these would be the correct purchase?

The resistors look fine. I had a tutorial about Ohm’s law floating around here on the forum.

Thanks FJK. Nice to see you're still helping out :)
