I have quite a few lights, but no focusable lights. I'd like to try one out. Asides from the romisen rc-29, led lenser p5 and m5, what else is there? Between the three i've listed, what, in your opinion for your uses, is the best? (I do own better lights like quarks jetbeam fenix etc.. so don' try to encourage me out of a focusable light as i already have others).
