Omicron Review

Today’s review will focus on the Omicron flashlight by Gyorgy Kemenes. Gyorgy has already proved that he is a genius at creating the smallest of flashlights, prime example in case: the groundbreaking Nucleus flashlightand thisflashlight. The Omicron is simply the natural progression of Gyorgy working his way up in the flashlight world.


The aforementioned Nucleus flashlight. For size reference that’s FOUR Nucleus flashlights on a U.S. Quarter. 

Hereis the product page for the Omicron. Pricing started at $195 for the copper Omicron and worked its way up in price for the various metals and customization. There was still several titanium models left at last I checked. It is my understanding that once Gyorgy finishes a run of a model, that model is never produced again. My particular Omicron is titanium with bead-blasted finish and blue tritium vials installed.

When my parents asked me what I wanted for graduating high school, I gave it a lot of thought – I honestly couldn’t come up with anything until I asked my parents if it could be a flashlight. In good sport they agreed, although (like usual) they really had no idea what they were purchasing for me. If you haven’t already guessed, I asked for the Omicron. I’m sure that Gyorgy thought it was somewhat strange when the payment came from some Chinese lady, but hey, he couldn’t have known.

The Omicron arrived very quickly – Gyorgy is based out of San Diego, CA which so happens to be the state I live in. The light was packaged extremely securely and included detailed, printed out instructions. I like the included box with magnetic clasp. Here is a picture:


The Omicron itself is both small and light. The only other 10180 flashlight that I had for reference was a Mecarmy Copper Illuminex. Copper is quite heavy, so initially I was surprised by the weight of the Omicron. Here is the Omicron next to the Mecarmy Illuminex:


The Omicron is slightly longer, but also a lot lighter and slimmer. This is mostly due to the titanium vs. copper construction, but the Omicron also feels a lot more refined in the hand. 

In case there’s any doubt about the build quality and finish of the light, let me assuage such doubts. The build quality and finish are insanely good. Considering the size of the flashlight, it’s amazing the amount of detail that Gyorgy puts into the Omicron. I’m also a big fan of the bead-blasted finish after having the Omicron in hand.

The Omicron has numerous rings about the body and at the head. These are very useful in turning the light on and off, and allow for a more substantial grip.

If we look at the tail of the flashlight, the tail is how the flashlight operates. The Omicron is a twisty; you twist and untwist the tail to change modes. The tail of the flashlight houses six small tritium vials. You have your choice of blue or green when you purchase from Gyorgy, I chose blue. There is also an attachment point on the tail for a lanyard or chain. Surprisingly, the Omicron can stand on its tail.


I think it’s also important to note the threads themselves when twisting. The threads on the Omicron put my Haiku to shame: they are super smooth even though they are completely titanium. While the Haiku’s threads are good (not nearly as screechy as my Sinner Tri-EDC’s were) they don’t come close to the smoothness of the Omicron’s.

Specification wise, the Omicron is in another league compared to the 10180 lights on the market today. Firstly, it houses a high-CRI Nichia 219c 4000K, the same emitter in my Haiku. This emitter has grown on me and is my favorite after the Nichia 219b. Second, the Omicron is user-programmable and uses the GuppyDrv Rev 1 firmware. There are 24 selectable mode groups and a turbo timer. Such features – in my opinion – are part of what differentiate the Omicron from other similar flashlights like the Illuminex.

Some other aspects of the light worth noting are the orange-peel reflector and the battery  type. I’m pretty impressed Gyorgy was able to source a reflector for a flashlight this small, most other 10180 flashlights run a TIR lens. The 10180 battery type is great for neck and keychain style flashlights, but charging it can be an issue because most chargers use way too high of a current. I really wish that this flashlight had on-board charging, but understand that it would have been size-prohibitive and probably made it much more complex. As it is, I’ll be relying on my Illuminex to charge my 10180’s until I can pick up a Veleno USB charger.


The Mecarmy 10180 battery just so happens to be the perfect fit. There are several brands of 10180 that are supported, but be careful which you choose because of the extreme tolerances. 

I haven’t had the chance to use the Omicron in real-world use yet, but I suspect it will be spending most of its time around my neck. I haven’t put a chain or lanyard through the base of the light yet, so unfortunately there will be no shameless abs pic like with the Lux-RC Minion.

Speaking of the Minion, I want to do a brief comparison between the two. I think that a comparison is fitting because the two are part of the few custom neck lights out there. While I don’t think my Minion is going to be relegated to my nightstand any time soon, the Omicron is definitely the more practical of the two. I mean, how often am I really going to need to pump 1000+ lumens out of my neck light? I think that the output of the Omicron is plenty sufficient for its size. I’m not sure its actually 200 lumens as stated in the official sales post, but its more than enough for most any task. The Omicron is also smaller and lighter being made of titanium and taking a smaller battery.


 There are trade-offs, such as the magnet attachment on the Minion and the crazy output/runtime, but as a neck light, I can’t ask for more from the Omicron. 

Something else that plays in the Omicron’s favor are the tritium vials. Tritium is absolutely awesome in the dark when you need to locate your flashlight. Even though I have the Minion next to me on my nightstand, a lot of the time I find myself reaching for my Oveready BOSS because it has green tritium installed in the optic. Words cannot describe how cool tritium looks in the dark. My iPad Pro can’t do the look of the tritium justice, so I’ll let Gyorgy’s much better pictures do the talking:

All in all, I think the Omicron is something special – while there are a few things that I’d like to see implemented, the overall package is just beautiful. I love Gyorgy’s take on the 10180 flashlight especially because of its innovation compared to other flashlights in this battery category; manufacturers seem to keep pumping out the same 5/130 lumens twisty, USB charging, 10180 flashlight with different branding.

Something else that can’t be measured is the maker’s attitude and warranty. Gyorgy was happy to answer all my questions promptly and seems to really stand behind his products. Even when there was an incident with a CPF member in a photo contest for the original Nucleus, Gyorgy handled it very calmly and professionally. I definitely don’t think I would have been able to do the same if I was in his shoes, so I commend him for that. I also want to thank him for his permission to use his crazy good photos.

I sincerely look forward to seeing what Gyorgy decides to make in the future. As far as I understand, a 10440 flashlight is already in the works, so you can be sure I’ll be on the lookout for when that comes out.

Update 8/23/18

The Omicron has been around my neck for the past two months pretty much 24/7. It has completely replaced my Lux-RC Minion which I decided to sell after realizing the Omicron was much more practical for my uses.

I have purchased a Veleno charger to charge my 10180 batteries, and it performs admirably. While I do still wish the Omicron had on-board USB charging, battery charging is infrequent enough that it’s not a big deal. Most of my use with the Omicron is limited to the lowest settings, I tend to use it when I’m getting around the house in the dark.

Despite being around my neck 24/7, my Omicron is still in excellent condition and the finish shows little to no wear. It has withstood my salty sweat on countless workouts. I have also submerged it several times, the latest of which was swimming with it in shallow water for almost half-an-hour. Each time, it has functioned perfectly and shown no signs of water leakage even if turned on under water.

One thing I do want to note, however, is that mode switching and programming can be a tad finicky just generally speaking. Because the flashlight is turned on by the small tail, and the tolerances are so fine, the flashlight will sometimes skip a mode if you’re not turning the tail crisply. Not an issue that’s arises for me in actual use.
