I have promised myself I will leave this one alone, don’t know if I can keep that promise if the optic is improperly installed. Will just have to wait and see, I think it may have arrived in the States but I still don’t have a definitive arrival date…
If there were other choices of optics or it supported a larger domed LED I would buy a second one for sure. There is very little room to improve/mod this one (which makes me a little sad cause half the fun for me is modding to make my own unique version)
Make a switch cover that slides backwards to reveal the switch and while sliding backwards it also lifts up a lens cover!
You know you want to! 
Sunset mode finally turned off, all is well in the camp.
contactcr, try modding the E07 with larger wires, maybe check to see if the FET can be swapped for a slightly better one… there could be some lumens in there hiding somewhere.
Nitecore managed 10,000 with a 21700
And that relates to this 7 emitter FireFlies light, how?
So far I’ve seen reports of 7500 lumens using the XP-L HI in this E07, I just thought it’d be interesting to find what FireFlies missed. It’s, well, kinda what I do…
Edit: Since I’m going to try not to open this one up, I thought contactcr might want to find those poor lost little lumens in my stead.
… or try a driver and emitter swap. You know you want to replace those tiny little emitters with seven XHP 70.2. Perhaps you can be the first in the world to do so! :smiling_imp:
That TM10K looks pretty nice. 10,000 lumens from one 21700!!! … even if it can only sustain it for 7 seconds. Nitecore must’ve used a boost driver since they’re doing it with 6x XHP35.
However, the E07 does have a lot of advantages. It’s less than 1/4 of the price of the TM10K. And it has a replaceable cell.
I’ve pushed 70.2’s, burned up 70.2’s, not all that keen on trying to kill em 7 at a time. Now, 7 XHP-35…….
<—— Ham’r does 25,978.3 at start, still making 22,977 at 30 seconds and at an even one minute it’s still cranking out 22,528 lumens. 
A single Samsung 25S pushes 28A through the Ham’r, making 14,663 lumens from a single 18650.
there you go Dale! Your new project!!! Convert an E07 to run with 7x XHP35!!!
Well, I kinda do have something in mind that may allow the E07 to break 14,000, but we’ll see…
Take the lens and optic off, 10K, done
No real argument with anything youve said here. Except maybe the “trend” part—consider this.
1)- this is a hard crowd to please. Very detail focused. So things that would pass in conventional, commercial releases are a little more under the microscope here. A good example is the screw placement and broken optic leg. To notice this nearly invisible flaw, one has to disassemble the light. That is under the hood. In most applications this is where one sees how the sausage is made. That is a fussy detail. This is a fussy population. It does not from what i have read affect the function of the light. BUT, it is a fussy detail some people have taken exception with.
2)- some of the complaints i have seen are very subjective. Meaning they will not apply to everyone. Battery fitment as an example. Ff made a dimunitive light and it takes batteries on the smaller end of 21700 variability scale. This is frankly, in my opinion an age old Li-ion issue. All of my 18650 lites and batteries do not always fit nicely. I consider this subjective. Not necessarily a fault. The recommended solution is to buy batteries that fit based on advise in the thread. The problem is most folks are trying to make batteries fit that dont. This seems silly to me. And a “user operating error” category of problem.
3)- i just ordered a 2nd e07. My order number was 87x. Which suggests nearly 900 orders placed. Lets say there are 50 folks who have had complaints that should be rectified thru warranty. The subjective issues i dismiss. 50 is a high number based on the thread. But lets use 50 (as a totally arbitrary number) of problems that need to be fixed. From ~900 orders. Thats still a ~95% success rate.
What i have personally noticed in this thread a bit less than in the pl47 thread is there are some folks with very high expectations for a 55$ flashlight. There are some folks that really zoom in at impractical levels of perception and pick out stuff that almost seems irrelevant and at times rediculous. This results in an examination mainly by the 50 unhappy folks, and consequently very little is heard from the [presumably] ~850* happy customers. *(850 customers. Some likely purchased multiple lites per order, as i did.)
I do not consider it logical to consider the 50 negative experiences as a trend, if there are in the neighnorhood of 850 people with positive experiences. Perhaps, we differ on the meaning of trend. I dunno.
I buy alot of tools. I think long and hard about duty cycle when purchasing tools. If it is a one off gig, i may purchase at harbor freight or similar import cheap type outfit. With the expectation it is about 50/50 the tool will fail or will have a less than optimal duty cycle. If i need the tool to be used 8 hours a day for a year i will opt for a more reputable brand. Even the reputable brand will have failures. And need fixing ay some point but the understanding is that there is a higher quality control and better components.
In this analogy harbor freight is within 50-70% success rate. A milwaukee (similar) tool is in the 90-95% success rate.
I would argue that ff is in the 95% success rate category. But charging harbor freight prices.
That said, its your money, and your decision. I felt i had to provide some perspective because this place is a microscope that isnt always rational.
Again, just putting that on the table.
A too short battery compartment isn’t a “manufacturing error”. It’s a design error. Basically, Fireflies should have just designed the light a couple mm longer so there would be more space for the battery.
I certainly don’t think of my E07 as a “manufacturing mess”.
- Mine appears well built and looks great especially with the purple LEDs.
- The UI is awesome
- The beam pattern and tint look great
- The lumen output is astounding.
- The price is right
Sure you could spend $300 and get a few more lumens and better build quality from a Nitecore TM10K, but for the price the E07 is a superb light. And I quite like my ROT66 too.
well said!
i still like my E07
but FireFlies should use our findings and opinions for a V2...
Yes, I think there is a space for official or silent revision with longer tube. I plan to buy another E07 (and maybe more than one), but I will wait for longer tube. I’m quite happy with the form factor, UI and lumen output, so I hope they will fix the issues.
The Emisar lights are designed with specific batteries in mind. Most flashlights with a battery carrier or multiple cells have specific battery requirements. This is just how it works with certain lights. They want to make a compact/high powered light and this is how it’s done.
Received mine today from Neals Gadgets. I can see a philips head screw under one of the lens legs, so I have the screw issue. This doesn’t bother me too much.
I ordered a Samsung 40T along, it came undented since both threads were not fully tighened. But I was stupid enough to dent the top while tightening the tailcap, even though it didn’t feel like I was pushing it too hard. It’s a really tight fit. Later on I noticed that the solder blob on the head spring was pretty tall, so I reflowed it to gain additional space.
Also I feel like the switch could be more clicky.
But even with those issues I love this light. Those blue aux LEDs are gorgeous! The output is plain stunning (I’ve got the 6500k XPL HIs)!
I measured the standby drain with aux LEDs on on mine: it’s 0.56mA. Not sure how accurate that is, but this should give it about 9 months of standby time.
