Fenix E01 V2.0 Flashlight — Black

The Fenix E01 V2.0 is an EDC LED flashlight powered by a single AAA battery, built for anyone who needs a reliable light source on hand at all times. At 66.5 mm long and weighing just 13 g, it clips onto a keychain without getting in the way and is ready when you actually need it.

With three brightness levels, the E01 V2.0 reaches 100 lumens on high with a beam range of 35 metres — enough to navigate a dark environment, check over a bivouac, or signal your position. Dropping to the lowest mode gives up to 25 hours of runtime on a single battery, a useful trade-off when you want to conserve charge on a long outing. The LED is rated for 50,000 hours of operation, meaning the light source will not be the first thing to fail.

The body is metal with an IP68 rating, dust-proof and submersion-resistant, and it survives drops of up to 1 metre. These characteristics make it well suited to daily use in variable weather, though it is worth keeping in mind that the compact size and single AAA battery place it in the backup or secondary light category. For extended tactical use or weapon mounting, a dedicated flashlight with higher output remains the better choice.
