I own serveral LED torches and I have to say this one is by far the brightest, the zoom/pan function is handy too. The photo probably doesn't do the brightest justice but even on the widest zoom setting it lights up a huge area. Hopefully the quality stands up and it lasts but so far so good.
The torch comes with an adaptor to fit 3xAAA batteries or 1x 18650, I'd say you'd get similar performance from either configuration as the voltage will be pretty similar 4.5v for the 3xAAA or 4.2v from a 18650.
