30% off the original retail price!

This limited edition light comes in a bead blasted titanium body and uses the Nichia 219B LED with 93 CRI (Color Rendering Index).

Designed as the ultimate EDC (every day carry), the Atom collection features a simple two-mode interface, extended runtimes, and a neodymium magnet embedded in the tail for quick attachment to any ferrous surface. Sleek and fashionable, the Atom is the most practical FOURSEVENS flashlight. Every keychain should have an Atom.

Unlike most of our lights, the lights in the Atom collection are flood-type lights and do not have a parabolic reflector. This removes the hot spot and gives you a very smooth, wide viewing angle, allowing you to get the most out of your peripheral vision. Atom lights are ideal for doing close-up work such as automotive repair, where seeing everything nearby is more important than seeing at a distance.

Please do not use lithium-ion cells in the Atom A0 as it will destroy the light. See voltage range to select acceptable batteries for this light.

Operating your Atom A0 is simple. Insert the battery with the positive side (+) toward the head. To turn it on just tighten the bezel (head) fully. The Atom A0 will turn on when the bezel is tightened and turn off when the bezel is loosened. To switch between High and Low output turn the Atom A0 off and then on again within 1 second. If the Atom A0 is turned off for 2 seconds or longer it will then revert back to Low.
