4Sevens has breathed new life into the AAA cell by offering the Preon series of lights. More than a collection of individual flashlights, the Preon Series offers something akin to a buffet of options allowing you to truly make the light your own.
Meat and Potatoes
Aluminum or Titanium? How many cells? Clip, keychain, smooth? Twisty or clicky? Pick your color. These are the decisions that have to be made if you choose to go with a Preon. Built on a base of the slim AAA cell, the Preon is large light performance in an unassuming package. The use of a durable, solidly attached, deep-carry clip with the twisty Preon I makes for a light so easily pocketable and unobtrusive that it is nearly possible to forget you are even carrying it. There is now no excuse to not have a light with you at all times.
The Preons play host to the same winning user interface as the Q-MiNi lights. A simple Low-Medium-High sequence with 4 special modes hidden away where they won’t be accidentally activated. It is a good UI for a light that might be loaned out to the uninitiated since it only takes a few seconds to learn the basics. The three levels have been well spaced and carefully chosen to give noticeable increases in output or significantly better efficiency. Producing 70 lumens for almost an hour from an AAA cell is no mean feat, and increasing that to 160 with only one more cell is simply astounding.
The use of the XP-G in such a small textured reflector creates a beautiful smooth, floody beam that is perfect for close to medium distance illumination. There is a spot to spill transitional corona that further increases its usability. This light does use PWM to accomplish its multiple modes, however due to its extremely high frequency (2.6 khz I believe) this is completely a non-issue during use.
4Sevens proprietary matte finish anodizing for these lights is still being touted as type III, and after several weeks of torture testing I find I am inclined to agree. One of these Preon I’s was assigned the dreaded keychain duty for the duration of my testing. The only noticeable wear was at the point of contact between the body and the split ring used for attachment. The remainder of the body survived the incessant jangle and repeated drops quite admirably.
Constructive Criticism
Though the unique anodizing of the Preons does help to provide extra tackiness to the grip, it is still the dead middle of an arid winter here in the midwest. Between the lack of knurling and stiffer threading I was often left struggling for purchase when attempting one handed operation using the twisty interface. Even some subtle shaping would serve greatly to alleviate this trouble without even needing to resort to the standard rhombic knurling, thus still setting this light apart from the pack.
If the twisty is a little too difficult, the clicky option suffers from the opposite affliction. The protruding button of the clicky tailcap standard to the Preon II is so easy to push that accidental activation was the rule of the day. The frequency which I felt my pocket heating up from this light was quite surprising. In fact, I can confidently say that the interior of my pockets saw more of this lights runtime than I did during its time in the spotlight. Either stiffer springing or a more protected button is needed to reclaim this setup from a “shirt pocket only” designation in my book.
Conclusions
The fact that an AAA based light can compete with and even outperform most 2xCR123A based lights from only a few years past highlights the incessant march of technology. To do so in such a simple, yet elegant form however, is just shooting for extra credit.

I recently picked up the HA Black Preon kit. Was very disappointed to find that the clickie on the 2AAA body was not only too sensative, but the button rotated around the housing. Just gave the light a feeling of cheap construction. When I do carry this light, it’s only going to be with the 1AAA body installed.
If I had to do it over again, I’d pass on this one. Originally picked it up for redundant capability with my 2AAA Peak Eiger penlight. Quality on that light is far better. As far as the 1AAA format goes, the clip is better than the one on my AAA Maratac. But the Maratac is smaller, and can easily be worked one-handed.

Yes, I have to agree with most of those comments, though I have never tried the Maratac. I definitely like this light better in 1xAAA twisty format than 2xAAA clicky.

I love them! My favorite carry is the titainium head and clicky tail with a black Preon I body and a 3.7v lithium rechargeable battery. The 3.7v battery boosts the brightness beyond the Preon II of 160, to almost 200 lumens! OTF! This off of single aaa battery! The only precaution is to not run it on high for very long or it gets too hot. I’ve carried mine everyday for over six months and it has only come on in my pocket once. Were that to become a problem I would loosen the head, like a twisty, to lock it out. I love them! Thanks 4Sevens. And thank you, Dave, for a very nice review.

That would definitely be quite a unique little setup. Nice little tuxedo look to it. Glad I could help you out.
