I'll check and get back to you.
Is your torch 1 x 18650 or 2 x 18650 ?
Are you going to direct drive the LED ?
There's little reason to consider that a similar size resistor will get the same results, as my 2 x 18650 torch is regulated, so unless you have the save regulator and same voltage in, you won't get the same results.
