Quark Turbo AA Question | Can i make it brighter?

I just got this light. It's a really nice light. I was not amazed with it's throw but it's still very bright.



As always, when I get a new light, I want brighter. I just had a thought after reading in another thread.



Can you make the Quark Turbo AA2 any brighter?



Perhaps using a different battery? I can't find that thread I was reading or maybe I read it off a bit since I skimmed through it. Just wondering if anyone has tips/tricks to make it brighter? Can I use an 18650 with this? Maybe 14500?



Let me hear your brains.

Thanks again.
