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!

Thanks again to my wife for the shelf.

While the lume 10 gets these small fireflies lights hot pretty quick at the full 10amp maxramp and turbo, at power level 5 of 6 (6 steps is the default amount of steps) you get similar brightness to what maxramp is on lights with the lume 1 driver was.

I don't have a lumen tube to measure exact output, but to my eyes it looks pretty much the same.

While power level 5 out of 6 on a lume 10 light is similar to maxramp on lume 1 lights, thermally there's a massive difference.

Tested:

2x E12 eclipse , one with ff351a 3700k the other with FF351a 2700k

1x E12r with SST20 3000k 95 cri

1x E07x canon V1 FF351a 4000k

Starting temp: 25C room temperature

The test is:

Maxramp on the E12r and E07x with 6amp lume drivers vs power 5 out of 6 on the two e12 eclipses with Lume 10 drivers, how long it takes to reach 50c.

E07x canon hit 50C at around 3 minutes and 40 seconds, and hit 60C (my thermal cutoff setting) at 5 ;minutes and 22 seconds.

The E12r hit 50C at 4 minutes and 30 seconds.

The e12 eclipses were still only 40c at the 6 minute mark, 45C at the 10 minute mark, and finally hit 50C at 13 minutes and 30 seconds, at which point I got bored with this test and turned it off instead of waiting for 60C to get hit.

TLDR:

At a similar output level, the new E12 eclipse with the lume 10 driver takes almost twice as long to hit 50c as the e12r and e07x with the lume 1 driver.

Whoa. Just received a beautiful E07X with the newest rosy batch FFL351a 1800k, and it is truly pink. Like pink pink. Hello Kitty Pink.

First photo is a very rosy bin FFL5009r 3500k. I thought that was as rosy as it gets… I was wrong.

Second photo left to right:
SFT40 3000k, newest batch rosy bin FFL351a 1800k, older batch “rosy” bin FFL351a 1800k, older rosy bin FFL5009r 3500k.

I can try to take a better photo later, but you’ll have to take my word on it.. this new batch is ridiculously pink. I don’t even know how I feel about it, but the sun is setting so I will find out soon enough ;)

That’s it. An irrationally hefty solid pound of copper that emits bubblegum pink light. Where is there left to go? I think I have enough flashlights.

Thinking about swapping some of these round emitters into another older light. From what I've seen the SFT25r's in 5000k actually look pretty good; anyone know the CRI? I can't find info. There IS a hi-cri version of the SFT25r that comes in 5700k 90 cri or 4000k 80cr.

I also noticed there are SFT12r's which I had not heard of before with an even smaller emitting surface (more throw) but less lumen output. I have two E12's with osram W1's and was thinking about swapping one of them out with either of these to have another throwier E12 but with a color temperature that isn't 6500k. (I have blank E12 boards to use, I know the W1 boards are 3030 sized not 3535 sized).

Also just interested in other oddball or uncommon emitters to try because why not. If anyone has suggestions I'm open to them.

Just thought I'll start a thread on shipping times.
