FourSevens Preon P2 MKIII: Brightness in a Compact Package

Compact, Bright, Reliable, User-Friendly Flashlight

In the grand tapestry of life's adventures, sometimes it's the smallest tools that make the biggest difference. This could not be more accurate when it comes to the FourSevens Preon P2 MKIII.

It's not just a flashlight, but an emblem of relentless refinement and meticulous attention to detail. A piece of equipment that has been honed to its absolute peak over a solid 11-year period. It's the testament to the idea that good things truly take time.

Being AAA battery-powered, it brings to mind the age-old adage: dynamite comes in small packages. The punch of brightness this compact device packs will astonish you. Surprisingly bright, not as a feat to awe your companions, but as a trusty companion that lights up the path when you need it the most, and fades into oblivion in your pocket when its duty is done.

Staying popular over time is not for the faint-hearted – it requires delivering consistent quality, and the Preon P2 MKIII does that with aplomb. The third generation of the Preon range, this little gem has a legacy of refinement and persistent improvement. It stands at the zenith of AAA tail switch flashlights – an end of the road achievement that speaks volumes about its unwavering reliability.

In this iteration, you will appreciate the robust clip that comes with improved geometry. No longer will it shred your pockets like previous generations – the under-clip grooving has been eliminated, balancing a secure hold with smooth engagement. This practical, pocket-friendly feature means you can stay on the move without a worry.

One of the issues that have been ironed out is the “hot pocket” problem. Previously, the tailcap was too easily turned on while in the pocket. That's no longer the case. And, of course, the High CRI Nichia LED assures high beam quality.

The new Preon offers a ‘Burst Mode', a fantastic feature ported over from the flagship Prometheus Alpha Flashlights. This allows you to access maximum output at any time without scrolling through other modes, giving you the right amount of light whenever you need it. It also conserves your battery when you use the standard high mode for regular use.

The light comes with Hybrid Memory, a blend of memory and no-memory. This innovative configuration saves the last mode used, but reverts to the first mode in the sequence when shifting out of a saved mode.

Another thoughtful feature, exclusive to Prometheus and Foursevens, is the Digital Bump Protection. This prevents accidental mode changes if the light is dropped or tapped on a surface when tail standing, which is a very real possibility during an active lifestyle.

Lastly, this flashlight is a salute to DIY enthusiasts. Its user-friendly design allows for easy disassembly and reassembly, making tinkering a breeze.

All in all, the FourSevens Preon P2 MKIII is a great partner for those who love the outdoor life. Its compactness, versatility, and attention to user-friendliness make it a staple item in your kit. Just like the greatest adventures, the best tools are those that deliver the goods – no fuss, no frills, just rock-solid performance when you need it most.
