Preon P1 MKIII

$75.00
Introducing the Preon P1 MKIII: the most refined AAA clicky light on the market. The first Preon was launched in 2010. We don't release a new light every 5 minutes, because we spent the last 13 years making this one better.

The 2024 Preon features the newest Nichia 519A 9080 LED @ 4000K and 90+ CRI. We also managed to increase the output by 50% giving the P1 a maximum output of 150 lumens.

Orders placed after 02/21/2024 will ship some time in March, after we finish shipping Early Bird pre-orders. If you purchase other items, we cannot split your order into "ship now" and "ship later." Thanks for understanding :)

    The third time is the charm: Introducing the third generation Preon P1 MKIII, the most refined preon ever.

    Product Details

    A Foursevens staple: The third generation Preon MKIII is AAA battery powered and surprisingly bright. The Preon has been around for a long time and represents the pinacle of AAA tail switch flashlights. It's not meant to impress your friends. It's meant to deliver plenty of light when you need is most, and dissapear in your pocket when you don't. Products don't stay popular for this long without delivering the goods. Like most Foursevens lights, the Preon has been refined and updated many times over the years. The MKIII represents the end of the road, there's just nothing left to improve in this form factor. That's a bold satement and thousands of owners will back us up.

    The MKIII Preon features a stronger clip with better geometry. The grooving was removed from under the pocket clip. The previous generation had a reputation as a "pocket shredder," as do many lights. The tailcap was also revamped to eliminate frequent "hot pocket," meaning the tailcap was too easily turned on while in the pocket. Finally, a High CRI Nichia LED delivers on beam quality.

    Alkaline Battery Warning

    Alkaline battery damage is the #1 cause of failed lights. Alkaline battery damage IS NOT covered under warranty.

    Alkaline batteries will power the Preon, but we strongly discourage their use. Alkaline batteries leak and/or produce corrosive gas during use. This will destroy your flashlight. Every Preon ships with an included rechargeable NiMh battery.

    Batteries Included
    All Foursevens lights ship with premium rechargeable batteries included. They deliver maximum brightness for longer and save you a ton of money.
    Burst mode
    This feature is ported over from the flagship Prometheus Alpha Flashlights. It allows you to access maximum output at any time without scrolling through other modes. This also allows you to have maximum output when you need it, but conserve battery by using the standard high mode (60% output) for normal use.

    Using a very fast double press, burst mode (100%) output is directly accessible from any previous level, and reverts to the last saved mode. Experts agree that most flashlights are used at lower level outputs, but sometimes you need to dial it to up. We've got you covered on both counts.

    Hybrid Memory
    A blend of memory and no-memory, the hybrid configuration saves the last mode used, but reverts to the first mode in the sequence when shifting out of a saved mode.
    Pocket Friendly
    I eliminated grooves or knurling under the pocket clip to ensure your light won't destroy your pants pocket, while maintaining the secure hold and smooth engagement you expect from my pocket clips.
    Digital Bump Protection
    Exclusive to Prometheus and Foursevens, Digital Bump Protection prevents accidental mode changes if the light is dropped or tapped on a surface when tail standing. The software detects very short power interruptions and ignores them. Other lights will think you've requested a mode change.
    diy friendly
    *warning-nerd content* This industry was created by individual makers and modders working at home on their kitchen tables. People who love tinkering, technology, and flashlights! Unlike most industries, flashlights have been driven by the little guys and we intend to honor that tradition. Most manufacturers (including Foursevens in the past) glue or thread lock on certain components so they cannot be disassembled without a lot of effort and/or destroying the light. This was to prevent people from tinkering. I say tinker on my friends!
    Included with your Preon
    • Preon MKIII Flashlight
    • GP Recyko Pro AAA battery
    • 2 Spare O-rings
    • Instruction Manual

    Operating your Preon is simple:

    • Make sure that the battery is inserted with the positive side (+) toward the head.
    • To turn it on press or click the tailcap button. A press allows momentary activation of the light.
    • A quick off/on cycle changes modes
    • Two very quick off/on cycles activates burst mode
    • Enter configuration mode with 10 on/off cycles in less than 3 seconds: The light will begin to blink a number of times corresponding to the selected configuration. For example if you are in Config. 3: 3 blinks, pause, 3 blinks. If there is no input for 5 seconds the light will exit configuration mode.
    • Turn the light off for 5 seconds to save the current configuration to memory

    All Preons are initially set to Configuration 3 with Medium/High/Burst. They can be reconfigured as often as you'd like.

    The best pocket clips on the market
    Pocket clips are my jam because I obsess about every detail, because every detail matters. The new clip is made from thicker material, provides easier pocketing, and improved grip. Most of the "grip" on a flashlight comes from the pocket clip, not the surface finish.
