NB Drive Parameter - When FV of the LED and input voltage match...

Forgive the noob question, but I've been searching the forums for my scenario without coming across it yet.

I'm using MWS parts and a NBv3. My power source is a single 3.7V 18650 battery. The LED I've chosen, Green Cree XP-E2, has a forward voltage of 3.7V @ 1000 mA. I've gone through all the calculations and keep ending up with "0" resistance as the result, but I feel like I'm missing something.

I'm thinking I'll be cautious and solder on a .47 ohm/.5w resistor just to have something minimal in place, but would this be a scenario where I should simply lower the NBv3 drive parameter prior to getting the resistor just to test the overall setup?

It's 3.58 not 3.7. I just looked at the product page and it does say 3.7 but that is a typo. You should be fine with the .47 ohm.

Ah-ha, I knew something was up. Thanks.
