Make sure you're 100% studied up on safety. I just spent the past two months getting it all together, reviewing it and then, reviewing it again. I've got ohm's law in my head now, I don't need an app or website. That's how detailed you need to be.
I've got a DMM for the house, and a 510 ohm reader to stuff in my briefcase, (well, it's currently in my online shopping basket. Just double checking I have all I need).
And saying you have an ICR battery is just not enough! Sorry.
As has already been said, each to their own. Everyone prefers a different 'kind' of setup, every setup has its own learning curve. Again, sorry. But it really can be a lot of fun if you have the patience. And those very informative flashlight forums are just awesome. Almost got me into flashlights
Be safe and enjoy the ride.
