Fenix E202014 EditionFenix has been pretty busy updating their flashlights, but you know they've spent a little extra time on this bad boy, they call the E20. This unique LED light features a user interface we have yet to see from any other manufacturer. The E20 features a motion control user interface that will definitely get the attention of those around. Measuring in at just over 6&quout;, the E20 features a premium Type III hard-anodized anti-abrasive finish on an aircraft-grade aluminum body that will withstand the rigors of the outdoors. Just pop in two AA batteries and you'll be ready to shake and shine at the next camping trip, hike, or adventure.Lighting TechnologyJust Shake It!Now comes the best part of the E20. You don't need to worry about finding side switches or tailcap switched to switch modes. You simply shake the light to select the different outputs. Tilt the head of the light downwards and shake it for optimum sensitivity. You can prevent accidental activation by tightening the head and lock the light on the current output. Loosening the head will resume the shake-to-shift interface. Equipped with a CREE XP-E2 LED, the E20 outputs a very bright 250 lumens while in High mode. Shake you way down to the 125 lumen Mid mode and once again to the 10 lumen Low mode. You can squeeze a maximum of 60 hours of run time while in Low. The intelligent memory circuit makes it so you can revisit the last output mode used, so there are no surprises. Also, the E20 features a digitally regulated output, which in turn maintains constant brightness.PowerWidely Available and InexpensivePowering the E20 are two widely available and inexpensive AAA batteries. You can use a primary Alkaline battery or go the rechargeable route and use a NiMh battery to get more bang for your buck. Reverse polarity protection guards you against inserting the batteries improperly and possibly damaging the light. You don't have to worry about shorting out the batteries or the light because the E20 is IPX-8 rated and can be submerged underwater up to 2 meters.
