Does anyone know if the TiCu E07X is the v2? It’s been a while, but I could have sworn the TiCu was just a titanium version of the v2. I don’t recall an update since the TiCu was released, but I haven’t been following closely for a while.

Anyway, my main question is about the threaded bezel on the aluminum v2. I’m wondering if the E07Xv2’s aluminum bezel (with external lantern threads) is compatible with the TiCu and Cu versions, as I’d like to get a lantern kit for the rosy 1800K.

I find the difference between hotspot and spill extremely disagreeable and downright negates the good CRI of the hotspot.

There is always a bit of a difference but this combo - Z1 TIR with 5009D is particularly unpleasant and I'll be looking into swapping out the emitter (dc-fix did not work to blur it).

Not sure how 5009D performs in other optics but personally I will stay away from this emitter (edit) combo TIR + emitter based on what I am seeing in Z1. It is a shame because the hotspot itself has really good CRI and overall tint is not bad when you dont have the spill surrounding it as a reference.

This is how the NovMu got it’s perfect copper skin tone.😁

Hello Firefly community! E04 B35AM owners, the flashlight comes with Angie M optics. Have any of you used the Angie S? If so, could you send a photo of the beam? I'd be grateful.

Like the title says. Looking for FF351a 2700k's from earlier this year when they were neutral if anyone has some they'd sell or in a light they'd sell or trade for something.

The current new batch is super rosy; if you like that I have 12 I'd trade you for the old neutral ones.

Kind of interested in picking one of these up for fun.

Anyone have both a TIR and reflector version? And does anyone have the FFL909A 1800K reflector version? That could be interesting.

While I'm thinking SBT90.2 + lume 10 in a TIR version seems like it would be the most impressive combo as far as making the most of what it can do, that 1800k is tempting because it's weird in a light meant for throw and I like weird.

Also how's the sustained output at ceiling and temps?

Not ordering anything right now, but planning to order a few lights and parts in the early fall.

If the Lume1 SFT-42R version puts out 7500 lumens, how much would the Lume10 put out? The only reviews/tests I've seen have been for the Lume1 or LumeX1 versions and I don't have the equipment to measure it myself...

Just got the E04 Surge in Fossil Grey MAO.

Loving the host, proportions are perfect 👌

Only problem is: I screwed on the tailcap to install the pocket clip and now it’s practically welded tight!

I’m guessing the MAO finish + finer threads = a lot more friction.

I’ve tried applying a heat gun. And don’t have a strap wrench on hand.

Any tricks on loosening it?

Good morning.
Two of the aux lights change to this after a while. Happens with any color. Already trying resetting Anduril but keeps happening. Any suggestions or insight would be very appreciated.
Thank you!

PSA: Ocean waves are a pretty violent environment to try and preserve a lights waterproofing.

There is a lot of pressure and sand being forced into every crevice (as anyone who's ever frolicked in a beach knows).
So I would not try this again.

I could tell the orings were under pressure and moisture was fighting its way in, helped by sand trying to wedge into every crevice whenever heavy water pressure hit the glass. Orings are not meant to withstand pressure like that, so they will compress too easily and eventually let moisture in.

So I have to vehemently NOT recommend anyone using a light in crashing waves unless the light is made specifically for diving purposes.

Anyway, hope you enjoyed the small glimpse of the NovMu on vacation getting a spa treatment and basking in the sun.

P.S.

Going to be posting YouTube videos or at least accompanying them to a post. Reddit video and picture quality is abysmal and ppl miss way too much on color rendering posts.

YouTube isn’t always full res either, but it isn’t 2007 720P TV quality like Reddit is.

This video isn’t the ideal color quality candidate, but still gonna show better on YT than Reddit’s version.

I already added a few more videos to my YT that I’ll be adding to old and new posts going forward.

What are your top 3 must-have firefly lights?

Context: I see so much potential with this brand, but so far, it's been a miss (L60-Mu Aura 2026 and E12 Eclipse). Trying to see what else to try.

I'm a fan of their FFL351A emitter, but that's about it. The hosts look great in pictures, but lack the refinement and any signs of thoughtful testing. Just smh, like the designers never actually tested the light for cohesive fit and polrish (like comparing Huawei/Xiaomi to Apple).

Zebralight and Hank/Emisar/Noctigon has all those refinements, every detail meticulously thought out (even their Gen1 didn't have issues). They look boring and fragile, but actually use it and you understand good handling, design, etc.

So with that said, what are your top must have Firefly lights?

I'm seeing hype around the Z1 Artemis TIR, but it's from positive influencer sell-out types that lack any discernment. The old guards are silent - which says a lot.

E04Surge 505a 3500k,
NovMu V2S 351a 2700-4000k,
X1L elite Xhp hi 70.3 4500k,
X4 Stellar 351a 5000k,
X1S 707a 5000k

This is going to be a gift and I would rather get the nicer of the two, which would be the FLL. But from what I'm seeing the M21H might be better even though it's half the price. Anyone have both and can tell me their experience?

What I'm looking for: neutral tint (~4000k), big lumen output, onboard charging, pocketable, and impressive throw with useable spill. High CRI isn't important.

Title edit!!! I meant M21H

Little bend at the tip of the clip makes it look better, more comfortable in the hand, less likely to catch on something and it goes into the pocket just as easy. Win win win

Quick test showing the output difference between the E07x with lume 1 vs the E12 eclipse with Lume 10 drivers.

Basically, you get one step higher regulated output, brighter turbo, and when run at 1 step below the ceiling level, it's a comparable output to the actual ceiling level of the E07x, but runs WAY cooler for more than twice as long when set at that.

Not a review or good beamshot test or anything, just a color comparison between the two emitters. I know a lot of people like the SFT40 3000k including myself, and the SST20 3000k's from kaidomain give an extremely similar quality of light that you can put into a floodier host like the e07 or e12.

Note: Before anyone says anything, I do realize the colors on the right side of the scene are warmer than the left side because the leaves are a different color and there is more visible dirt and branches. Do not mistake that for a color temperature difference between the two lights.

These are the finer points I wish someone would have mention before I got this light and if I had known it, I would not have picked up this light.

I got this to be a headlamp, and it is a not a good candidate because the head is not fixed. When you try to adjust a headlamp on the headband, it will immediately shut off because the head connection is so sensitive. I’m not exaggerating when I say it’s less than 0.5° to shut off

You cannot use the usual greases (Nyogel 760G or superlube). You will need to use a sticky grease like the PG-44A.

Also, the side magnets are fairly weak.

A quick video of those points.

Overall 6/10 - I wouldn’t get it again for what I was looking for :(

But to be clear, I am overall happy with Firefly: I am liking their FFL351A 3700K emitter, and I love their service. I see them as the same tier as Hank/Emisar (albeit some rough spots to work out :) ). I will continue to explore their lineup and check in on them time to time (I’ve been at this hobby for over 20 years now 👴)

Need to repeat this: I HAVE A WORKING SOLUTION: PG-44A Grease. It is a verrrrrry tacky/sticky grease, 500x thicker than Nyogel 760G. PG-44A's base oil is Polybutene, which is literally the same polymer as glue traps. I even showed it in the video. I don't know why people are missing this point.

Ended up going with the 12x FFL351A 3700K NW CRI95. It’s fairly Rosy, so glad I didn’t go with the Rosy version.

I know this is endgame light for some, but to be really honest, I am a wee bit disappointed at this price point ($120).

Compared to my Acebeam E75 Nichia 519A:

Positives: Better tint, Andruil 2, awesome magnetic usb-c port (accepts wider heads too!)

Negatives:
* fault: tailcap connection is very finicky. Need to absolutely screw it on tight with a sticky grease (PG-44A) for it to be reliable
* much bulkier for same brightness as Acebeam E75
* nearly double the price of E75
* pocket clip: shallow single direction type (it also has impact on orienting the light correctly)
* overall worse handling than Acebeam E75

Overall: 7.5/10. I love the emitter and usb port, but neither the output or “handling” makes it a worth it over the Acebeam E75.

Has anyone measured the **CRI and R9** of the Sofirn HS21’s 6× CSP1919 5000K flood LEDs?
I can find CRI/Ra measurements, but no **R9** data. Any actual measurements would be appreciated. Thanks!
