Wiring Harness Question

[Cire Yeldarb]

Using the LED resistor calculator I use, I got a 2.2 ohm, 2W resistor for that setup

[Generic Jedi]

R = (3.7-2.3) / 0.7 = 2 Ohm
P = (3.7-2.3) x 0.7 = 0.98 Watt
So a 2 Ohm, 1 Watt resistor should be fine.

I got the same. And looks like those are readily available in the shop.

Ok, new problem. How do you splice in the resistor when using the mad prebuilt parts?

[Generic Jedi]

Cut the JST of off the LED, but leave enough wire to solder it to one leg of the resistor. Solder the othe leg of the resistor to the wire left on the LED. You'll have to cut both wires on the JST and splice in a wire on the un-resistored side to keep it even.

Ok, now I just need to find the 1.2 ohm and watt resistor for the cree less since they're in stock
