Instead of a more traditional push-button on/off switch, this 12.7cm torch from Foursevens uses a bolt-action mechanism to turn on and off, or toggle between one of four different output modes including an emergency SOS signal.
On a fresh set of batteries, at its lowest brightness setting, the Bolt Light will run for upwards of 102 hours before dying. But at its brightest setting, it’s only good for just over an hour of continuous use, so you’ll want to strike a balance somewhere in-between. Especially since the $US100 torch uses a pair of expensive CR2 batteries which aren’t always the easiest to come by. [Foursevens via Cool Material]
