So help me guys as I am in New Zealand without the ability to walk into a place like goinggear and seeing all these lights albiet you canot try them out. I am looking at a few EDC lights and a larger duty type light. I already have a HX120 from Insight which runs off 1 x 123 and it is brilliantly bright but for the small lights I have been considering the following. Let me know what you think. Fenix LD01 AAA, Preon 2 R5 2 x AAA, Fenix LD10 1 x AA, Fenix LD20 XPG R5 2 x AA, Fenix TK21 US (no videos on these yet by goingear) 2 x 123's. If I am going wrong anywhere let me know. Brightness/Throw is what I want predominantly and after than run time and smallness. My duty light will be the Fenix TK50
