yep, Fenix LD20.
the reason i especially like it is its slimness. i like the legnth so it can still be used as a striking tool. but its slim enof that you dont notice it in your pocket. the LD10 is shorter and because it uses the thinker 123 batterys, it bulges in your pocket.
also i like the fact that it is simple. high output. low output. AA batterys. but still 180lum output. waterproof.
