Fireflies E07 preview

And I found it from xamsiem on Reddit.

I may be tempted to mix and match.

Maybe put this head on my clear coat body. And the copper body on my clear coat head. I don’t know….

I’ll taker an all copper one.

I did find out about this light about 2 weeks ago, I thought that this was the ultimate EDC light. Was little bit surprised never heard about the manufacture before.

I have spent the whole saturday to read this thread. In general its way too much off topic in this thread especially of people who dont own the flashlight.

Here is Some observations and questions to summarize this thread

1. It seem Fireflies first of all have done a bad job giving back feedback, about all manufacture and quality problems, I only have seen one post, about the thermal paste. From that point forward we know they are aware of the problem, but we still see no confirmation that all flashlight from a certain date should not have this problem, all I see is people from left and right have this problem, right now I cant make purcahse cause it feels like russian roulette and its a big pain to send back stuff and get it fixed even if they pay for everything, I rather wait until beta period over.

2. Its a lot of of battery discussion in thread, some battery discussion are valid, especially those regarding size of battery, It must be under 70.8mm in length. The other discussion of the danger to use to powerful batteries might make some emitters blue or stop working is also very important disucssion,

The other dicussion regarding fake batteries from fireflies, well, first of all fireflies should not bundle with battires, its a risky business its easy to get fake batteries, especially since they most likely want to make as good profit as possible so they buy the batch that has best price. Fireflies will earn money of bundle fake batteries. Its better to buy batteries from shops that only sell battires where their whole reputation is on the line if they sell fake battries, here in EU I recommend NKON.

3. There is very little comparison between emitters in this thread, I think there is a lot of “Nichia” fanboyism in general on this forum, sometimes its well deserved but that does not mean we should give other emitters a chance. I am in the market for the 4000k range myself, but the CREE XPL HI V2 5A 4000k emitter have 2400 more in lumen output, then both Nichia and SST20 4000k, so yeah thats a really big difference in output, so there should be a very good reason to choose the Nichia over the SST20, sure I dont see the CRI rating on the Cree XPL, but I would prefer to see actual photos to see the difference in color/tint/beam/battery efficiency.

4.

Now it has gone almost 2 months, have we seen any “official” proof that it will be released ? and when ?
I rather way for the premium edition with Copper and that have hopefully fixed all the glitches in the manufacturing. Black body and copper head would look sexy (just like Manker E14 II).

I’m also keeping my eye out for the premium copper/titanium E07. I might splurge on it. My nichia 219b E07 is one of my favorite lights now. I love the size, it looks awesome, and performs great.

I’m surprised no one has mentioned the 219B version is listed as in-stock again, for both the E07 and the ROT66 (but not the PL47).

The listing does not explicitly say SW45K (I don’t know for certain whether it did before), but it does specify R9080.

Does any one have a beamshot comparison between XPL Hi V2 5A 4000K and SST20 4000k. I am not interested in the Nichia, they have more quality problems and the blueshift problem is not something I want to risk.

There is a big lumen advantage over the SST20, I also read that the XPL HI have superior thermal performance it means that I would be able to run on turbo for longer periods then the SST20.

Noticed that the banner to the left is now advertising an E07 VII. The website says new version since the beginning of March, but does not say what the changes are? I assume it probably has the cooling fins rounded off on all colors now, but can anyone confirm? Any other changes?

I have one that I’m pretty sure is VII, slightly bevelled fins indeed, undamaged optics and a ledboard that sits flat on its shelf with ample thermal paste. I’m not sure if there’s more changes. I modded it with a few new leds already: What did you mod today? - #7230 by djozz

Version II is also supposed to be 1mm longer so it can accommodate larger batteries.

My 50E is 70.9 mm and my E07 version fits that precisely, you do not want the battery longer.

Perhaps useful for someone somewhere.

I set my (SST-20 4000K, slightly altered by swapping 3 of the leds to SST-20 2700K) E07 at 5 lumen, which is a great brightness for longterm trail-following without tiring the eyes with too little light, and measured 20,13 mA.

That translates to 62 lumen/W system efficiency (pretty good for 98 CRI), and on the Samsung 50E that it houses now (I measured 5200 mAh at 500mA discharge in the Opus) that is a continuous runtime of 10.7 days.

Some flashlights have terrible efficiencies at the lowest modes, but the E07 does well in this aspect. I reckon we have to thank Anduril for that :slight_smile:

Yeah not bad, especially since we are PWMing 3x 7135 to extemely low levels.

I dislike lanyards with rings and clips or that extreme thin piece of cord that must be fumbled in a tiny hole, but the rather deep clip groove of the E07 allows a simple and very strong way of lanyard attachment that I do like.

Ok, here’s a concern for the E07.

It is something that I always check on my flashlights and the E07 is the worst yet: the battery tube where the head-side o-ring groove is, is just 0.3mm thick. This is paper-thin, why did they do that? As this is about halfway the flashlight, as far as I can see this has major influence on the strength of the flashlight, which is built thick and sturdy everywhere else. I would (not :frowning: ) like to know what happens if you drop this light from some height and it lands a bit unlucky.

FTR and FWIW I rebuilt my lightbox with two internal baffle/diffuser panels cut ftom a sheet out of a Samsung 26” monitor. Then I used the Maukka calibration lights to come up with a very different multiplier. With the two diffusion panels there is no hot spot coming though to the meter, not even from a White Flat. My multiplier changed ftom the previous .345 to the new .436.

One of the lights I tested after this is the new black E07 with 6500K XP-L HI emitters that Neal sent in place of my GT Micro lights. With a fresh charged 30T this straight out of box E07 does 6627.2 lumens at start. A little less than the 6900 claimed on the site.

Ham’r shows 20,056, down quite a lot. The extremely throwy XSword on the other hand shows 379.32 , amazingly close to where it was before. Of course, percentages are huge numbers on huge lights.

you’re not getting your Micros?

No idea, haven’t heard another word from Neal since he asked specifics on what actually came. (That was the 17th)

I would like to have one in plain metal. Shiny.
Like the one you show in the pics, but don’t sell.
Easy to identify in rocks or grass. Thank you.

Cheers.

Thanks for the info!

Does anyone with a V2 know if the button LEDs match the blue aux LEDs now? It would be nice if they were updated to match like the ROT66.
