Ok, so I see it in the two 1lumen inages, definite chatter from what was probably dull tooling or unstable mounting during lathe work. The Reddit list I think is an unfortunate combination of FireFlies QC not cleaning the part and the super strong magnet piling the shavings onto the threads, nor a machining problem as much as QC (its bad but not as bad as poor matching).

When the friction surface is rough, those metal shavings are generated. In my case, it was the bad machining that caused the grittiness as well as metal shavings.

I also load the battery from the front, but I loosen the tail a bit so I can better align the head threads. I don’t use the clip.

Oh, ok. Wow. Well I am learning something here, and it is unfortunate Convoy has $20 lights with Perfect machining and these amazing FireFlies suffer from this machining, I’m hoping it’s an “isolated incident” since it appears the at least E07x and e12 are all machined similarly, and probably at same time.

Anyway, I hope Jack and FireFlies does something for the people effected. Even if that is a coupon code or allows returns for those who don’t want to do business with them

I love this community so much because it’s so helpful and enlightening. I’ve been thoroughly enriched and educated so much by being here. That being said…

Everyone literally crying about threads on a flashlight that is likely better than any other flashlight on the market is pretty mind-blowing. It doesn’t matter how many times you tell people to clean the threads, or to apply lube, or that you’re only supposed to use the head-side threads…or to just get the F%CK over it…people will still drown in a cup of water and trash Fireflies.

For those that can’t seem to find any useful insight on the new Fireflies because there is so much nonsense about “bad threads”, let me help you.

Fireflies makes some of the best lights the enthusiast community has ever seen. I do enjoy ultra smooth threads but this topic has gotten way outta hand now. No company is perfect, no not even Hank. But no one has pushed the community forward lately like Fireflies.

Hank was doing an 8 emitter E21A mule. Fireflies said 21 E21A emitters is more like it (that pushed Hank to do 16 emitters). Even now, no one has come close to producing the Nichia 219B lights FF has. Hank is making a 1200 Lumen E21A D4v2. FF had double that Lumen in the PL47G2 with Nichia 219B’s 2 years ago. E07 had almost 4000 Lumen of ultra high CRI light years ago too. You’d have to buy the K9.3 to beat that. Even the ROT66 Nichia is an absolute classic in raw aluminum. I get some pushback on “imperfections”, but some of this shit is just beyond overboard at this point. Not a single person here needs a replacement light because “the threads are bad”.

Here are the top 4 companies all things considered. Convoy, Sofirn, Emisar/Noctigon and Fireflies. Each one has their own strengths but, all are great at what they do. Everything else is just noise.

If you guys can understand all the endless complaining about some threads that don’t even affect performance…then you guys should be able to understand my need, my almost DUTY, to return the favor.

Yea! what @Lojik said!

 

see look, perfect threads

ok, ok.. im done.. 

 

But really, he is right. FireFlies is crushing it right now, and have been for awhile. i'm with ya @loljk.

My secondaries are no where near that bright!
Someone said there should be pots on the board that one could raise the brightness of the secondaries.
When I took out the optic, I did find 4 screws but I believe they are there to hold the board down.

@ftumch33, haven’t taken optic out but the pot screws are very small. Much smaller than board screws. I don’t believe this light has adjustable secondaries. Did you go through all of the settings for them? 7 clicks to access. I thought you would have already but just wanted to mention it. When I put mine on low they are very dim. Good Luck.

I sanded the surface down and now the threads are smooth. So it must be the rough surface that caused my bad experience.


So the threads on the head are not an issue? If not, no problem.

SST20 tests should be up in signature.
I think what I received was FA3 (which I requested, but wouldn’t have if I knew the DUV RISES with power, unlike FB4 which lowered with power increase), but he had said there was only FA4.

Yes, head thread are totally fine.

So here is a pic of size comparisons. The E07x is the exact same size as the Lumintop X9L sbt90.2 light. The head is like 1mm smaller, but they are almost an exact match, in case anyone has that and wants to know what itd be like to carry. The picture makes them look a lot different but they're almost identical.

 

What surprised me is the e07x is a little longer than the e12r , not that it matters at all but i didn't expect that.

 

The more i carry this light, the more i realize i would still recommend this to people even if the tail cap was WELDED ON. This e07x is awesome, it makes my other lights feel obsolete in a way. my tail threads are a little gritty on one of mine, doesn't even matter. This light is technically near perfect IMO. of course, as long as you are OK with the size.

Look, just cause you got the one light with perfect threads doesn`t deny the fact that some of these lights passed quality control as being `just good enough` and the people with less than stellar versions of this light have every right to make their concern known.

As far a Fireflies being better than any other flashlight on the market? I beg to differ.

The story of how one member had to use a vice grip to get the tail cap off was pretty sad. That’s outright unacceptable.

I appreciate you, Artiet59 and Boro. Based on how things were looking here, I didn’t really expect anyone to agree. It was really just for my sanity and for those that are truly wondering about Fireflies. But I’m glad it turns out that I’m not alone in feeling this way.

definitely, I couldn't agree more really. And in terms of FireFlies position in the ranking of best brands at the moment, I don't see how they aren't at the summit of that list in terms of design at least. I'd like to see more reliable availability but I get it, the world is weird right now.

And until I checked tonight I had no idea my e12r had gritty threads, bc it doesnt effect my experience at all with the light. I have been raving about my e12r, with gritty threads and all, for the last month. I didn't know about it and now that I do, I still wouldn't think to mention it to people when recommending the light, because it really doesn't even fall in the top 10 most relevant things about the light. That's how I look at it.

Fireflies, Emisar/Noctigon and Convoy are tied for 1st in my book. Lumintop and Sofirn are a really close second. I have no experience with astrolux/matreminco yet but I will soon. Everything else is either pure garbage or too expensive, or I haven’t tried…
I haven’t found another company where you can get 3-5k+ lumens for so cheap and have good build quality.

It’s ok if you don’t think Fireflies is better than other lights, I do and their performance has proven it over and over to me.

So many people were taking shit about Fireflies that some might get the impression that no one holds Fireflies in high regard, so I needed to rectify that.

@Artiet59 explained how his new FF made his other lights feel outdated, that was VERY much my experience also. Last thing on my mind was some threads that aren’t even supposed to be used anyway.

Some people are super quick to leave a bad Yelp review over the dumbest shit. I’m not like that at all. I always appreciate people’s effort and can understand the difference between something slipping through the cracks, and something being deliberately trash.

If a chef worked hard to make me a great meal and one thing ended up less then perfect, I would not throw away everything about the whole experience to shit and pile on the one mistake. I have far more respect for peoples work than to be so publicly petty to try and hurt their business.

Fireflies has put forth a tremendous effort in getting enthusiasts lights that truly excite. They have amazing anodization, aesthetics and excellent efficiency on top of emitter options to drool over. Compared to Fireflies, I can’t get onboard with what Hank has been doing lately. If the light isn’t trying to leap forward, why would I bother with it? His brand new 8 emitter E21A light puts out a whopping 1700 Lumen. Twice the size of the D4v2 yet only 500 Lumen more? I honestly don’t care how awesome his threads are, that is flat out mediocre to me just like the K9.3 is. If that’s your thing, more power to you and Hank. As for me, I will enjoy FF continuing to push the envelope on lights other companies wouldn’t even dare to make.

1000% Bro, threads don’t even affect the “flashlight” functionality of the device. It’s like me saying I don’t like the flavor of Coke because I like the threads that Pepsi uses on their bottles instead. I’m just like WTF???

The E12R looks SO SICK next to the other lights. Almost like a light from the future. The others look super nice too, but there really is something about the E12R that makes it look so tight. I carry it as much as I can but you’re right about the E07 being easier to pocket.

I agree, the aesthetic appeal of the E12r is on another level! It’s a beautiful light.

I like my NOV-MU. It has very nice LEDs with decent output. I also like the fact that it has an efficient driver that can sustain high output even with a near empty cell. Anodization is also nice. Very strong magnet is a plus.

But there are some things that I would like to see improved. Bare aluminum threads with poor machining is one of them. I understand that the threads has to be unanodized so that it is compatible with the clip, but there are ways to get around it. See KR4. Quality machining and smooth operation are very important to me, especially cosidering prices FF charges for their lights. I wish FF correct it. This issue comes up quite frequently because the same problem persists across multiple models.

Allow me to add a bit of perspective. The KR4 is a rear button flashlight, so the back threads/button área need to be right, for it to work right. On the Fireflies, none of them are rear button.

On the Fireflies, you’re also not supposed to open the tailcap except to swap clips if anything. So to Fireflies, they may not see the need to fix something that’s not really supposed to be being used anyway. That’s like insisting that a carton of milk or a box of cereal be easier to open from the bottom of the container because people want to know that it’s easy to open them from underneath if they ever decided to, it’s just not that compelling an argument to be honest.

I guess what I’m trying to say is this. How about you guys just open the flashlight from where you’re supposed to open it? You guys might enjoy your light a bit more if you’re not hyper-worried about dormant threads. If this makes me a crazy person, then… Smile

They both use the rear clip yet fireflies lights have grindy, unannodized aluminum threads.

Fireflies has excellent lights this generation. They’d be flawless if they had better QC, a better moonlight and better threads which are significant.

The E12R’s tail threads were not so good so unless I wanted to experience the grinding, I had to use the head threads.

The head threads were also not so good. They’re so thin, and coupled with the E12R’s relatively large and precarious head, as well as the need to apply a significant amount of pressure due to the stiff springs meant that I was worried and had to be very cautious every time I changed a battery to avoid cross threading the head.

This made me dislike the light and forced me to use the usb-c charging every time which is rather convenient but I still want to change batteries without worrying I’d break the light with one wrongly tilted turn.

This was a significant issue to me with fireflies lights and not something I worried about with any other light.

Changing the battery from the head of the D4V2 is not a good experience because you have to push down pretty hard. The E12R is like that but so much worse, and you can’t even use the tail threads on the E12R while the D4V2 has very smooth tail threads.

They’re so thin, and coupled with the E12R’s relatively large and precarious head, as well as the need to apply a significant amount of pressure due to the stiff springs meant that I was worried and had to be very cautious every time I changed a battery to avoid cross threading the head.

This made me dislike the light and forced me to use the usb-c charging every time which is rather convenient but I still want to change batteries without worrying I’d break the light with one wrongly tilted turn.

This was a significant issue to me with fireflies lights and not something I worried about with any other light.

Changing the battery from the head of the D4V2 is not a good experience because you have to push down pretty hard. The E12R is like that but so much worse, and you can’t even use the tail threads on the E12R while the D4V2 has very smooth tail threads.

I’m just not that worried about it. But if my light does happen to break, I’ll be the first one to come back and tell you you were right.

In the meantime, like I do with all my lights when changing a battery. I will take my time, I will be careful and I won’t be reckless. If it’s such a big concern for you, I suggest you do the same too and you’ll probably be just fine.

The one saving grace is you can turn the tail cap a few revolutions to ease the compressions the springs are under, making it easier to screw and unscrew the head.

Looking at https://budgetlightforum.com/comment/1501768#comment-1501768

I think the emitters are FA4 after all. I should test turbo, but haven’t bothered because the colormunki is spewing some bs garbage that sensor is oversaturated and refusing to measure

Odd considering it has no issues with 180k lux from the C8 a year or two ago

Favorite lights:

Fireflies NOV-MU 21 4500k E21A

Fireflies NOV-MU 21 200k E21A

Fireflies ROT66 219B SW45 D220

Fireflies E07 Copper 219B SW45k? (odd/higher lumen bin with lower r9 and higher cct?)

Fireflies E07x Pro sst20 FA4 4000k

To anyone who has threads that are problematic on any light. I have a solution that I am pretty sure will help. First clean both sides of threads then put rubbing compound or polishing paste on one or both sets of threads. Might be a good idea to remove gasket. Then proceed to screw in and out. When done clean and test. Hope this helps.

Hmm, never thought of using polishing compound.
I might have to try it.
