I enjoy my L1 very much, but there are a few things of which you should take note. For one, the L1 will seem considerably larger (longer) than an ARC LSH. For the most part, the L1 will make both of your current EDCs obsolite provided you always have it on you. The low is a bit dimmer than the Arc AAA, but IMHO its a perfectly functional brightess and its actually better for close up work. Low also sports a fantastic runtime. The switch is my favorite thing about the L1- the button makes it very easy and silent to engage either of the brightness levels instantainiously and you can twist it for constant on for either level. If you do a search, you will find MANY more threads discussing both the new (which uses a Lux 3 and TIROS optic for lots of throw and no spill) and older versions (which use a Lux 1 and have more of a flood beam) of the L1.
